Congratulations!

Congratulations on purchasing TempLincTM, a small power line carrier (PLC) based

thermometer/thermostat that can be easily placed anywhere in any room with an AC

outlet. The TempLinc offers an easy way to monitor and/or control the temperature

in a room through PLC X10 communications protocol. The TempLinc can be set-up

in variety of different ways depending on the project's needs. TempLinc can be pro-

grammed as follows:

• To sendan updated temperature when a change in room's temperature is detected

• Send temperature when requested

• Act as a thermostat

• Operate in a combination mode that combines the thermostat mode with either a

report on change or report on request

All of this can be done in either Fahrenheit or Celsius temperature scales depending

on the project's requirements.

TempLinc is designed to be a general-purpose temperature sensor for home

automation use. It should not be relied upon for to prevent damage that may occur

if temperatures drop too low or rises too high. Because of the nature of PLC com-

munications, there is a possibility that signals sent by TempLinc may not be

received. The electrical components in TempLinc and its PowerLinc II™ powerline

communications interface module may fail or lockup upon exposure to temperature

extremes, even those that the TempLinc manual specifies that TempLinc can sense.

Additionally, like all home automation products, TempLinc should never be used for

life saving or life-preserving situations. TempLinc is not a replacement for smoke or

fire detectors and should not be relied upon as the only means of protecting a home

from freezing temperatures.

Key Features

• Reports temperatures between -60°F and 131°F

• Reports temperature in Fahrenheit or Celsius

• Programmable to transmit upon temperature changes

• Programmable set point reporting

• Uses RCS-compatible temperature chart

• Small sized sensor

• Includes new PowerLinc II Interface module with pass-through AC outlet

• Compatible with Smarthome Live and Smarthome Action

Compatibility with Third Party Home Automation Programs

TempLinc uses the same translation table as the RCS family of powerline control-

lable thermostats. Many home automation programs already support these thermo-

stats. When setting up the TempLinc for use with a home automation program, look

for support of RCS model TX15-B (it might also be described at "Bi-Directional" or "2-

Way").

Parts included with TempLinc

• The TempLinc sensor

• PowerLinc II PowerLine Interface Module

• PowerLinc II connecting cable

• Double-sided foam tape and mounting screws

Please note that this PowerLinc II interface is

designed to only work with the TempLinc sensor.

While it resembles our regular # 1132B PowerLinc

II interface, the two are incompatible and not interchangeable. The included

PowerLinc Interface contains different circuitry and programming to support only the

TempLinc sensor. The AC outlet on the front of the PowerLinc II interface is a pass-

through outlet for any 120-volt electrical device. It does not have any automation

functions.

Installation

Locate the TempLinc in an area that has good airflow and is located near an electri-

cal power outlet. The TempLinc can be mounted either vertically or horizontally, for

best results it is recommended that a vertical position be used. TempLinc is not

weatherproof and should not be used outdoors or for measuring water temperature.

Doing so may shorten the life of the sensor module.

1. The TempLinc comes with double-sided tape to secure it to the surface. Once

the location is chosen, make sure the mounting surface is clean and free from

dust, dirt, and debris.

2. Remove the protective sheet from one side of the double-sided tape to expose

the adhesive portion and apply it to the back of the TempLinc

3. Remove the protective sheet from the other side of the double-sided tape to

expose the other adhesive portion and place it over the mounting surface and

press firmly to secure it.

4. With the TempLinc secured in placed, connect the cable between the

PowerLinc and the jack of the TempLinc.

Do not plug the PowerLinc in until instructed to do so in the programming section of

this manual.

Because of the way TempLinc communicates over the AC wires, it may be difficult to

have other modules on the same house code used by TempLinc. You may want to

study the signals sent between the TempLinc and your home automation control

program(s) to find addresses for other modules. Or, simply set-aside the entire

house code for TempLinc's exclusive use.

Quick Start Instructions

1. Un-plug the PowerLinc II from the AC outlet for 10 seconds

2. Plug in the PowerLinc II into the outlet and wait three seconds

3. Within one minute of plugging in the PowerLinc II, send the following:

i. Send the base house/unit code of the TempLinc three times in a row

ii. Send the house/unit code for the Operation Mode

(see Table 1 on page 7 for operating modes)

iii For Thermostat modes, send the set point using unit codes

(See page 7 for more detailed instructions) 3

New Features in TempLincs with the PowerLinc II interface

With the changeover to the new PowerLinc II interface, we have taken some time to

implement some user-suggested improvements. Since most of the brains of the

TempLinc system are in the PowerLinc II interface, any TempLinc sensor and cable

will have these improvements when used with the PowerLinc II interface.

(Remember, the TempLinc must be used with a specially made and programmed

PowerLinc II interface.)

Status Request signals can be sent in any mode

Status Request commands are now accepted and responded to in any mode the

TempLinc is programmed into. Previously, TempLinc would only respond to Status

Request commands if it was programmed in the "Report on Request" mode.

PLC signals are now sent twice

To improve signal reliability, the TempLinc will send ON and OFF commands twice

(when set to one of the thermostat modes). Additionally, the TempLinc will hold off

transmitting if it detects signals on the powerline from other PLC transmitters. (This

is sometimes called Polite Mode or Signal Collision Avoidance.) By sending the sig-

nal twice, the odds are increased that a complete transmission of data will arrive at

the receiver(s).

Transmissions after a power failure

When the TempLinc is powered up (for the first time or after a power failure),

TempLinc will check the temperature and if it is beyond the programmed set point

(in the thermostat mode), it will send a PLC signal to activate the controlled device.

Send on Change mode now ignores small temperature changes

This was an improvement suggested by many of our users. TempLinc will no longer

send PLC signals if a small change in temperature is detected. Previously, when

TempLinc was in the Send on Change mode, it would send a PLC signal every time a

temperature change was detected. In some cases, this could cause a flood of PLC

signals and unnecessary cycling of equipment controlled due to TempLinc's temper-

ature reporting. With this improvement, the TempLinc will not send a PLC signal if

the temperature changes back to the previous temperature.

See Chart below

1625_web.qxd 6/24/2004 1:11 PM Page 4

Temperature sensing for Report on Change Modes changed

The TempLinc will now check for temperature changes every minute rather than

every eight milli-seconds. This change was requested because in some cases, the

TempLinc was detecting changes as a result of minor temperature disturbances.

For example, someone walks by the sensor or there is a sudden gust of airflow

across the sensor, the old TempLinc would have sent a flurry of PLC signals in

response to every change. When in the Thermostat Mode, it will still send an ON or

OFF the instant it senses a temperature change.

Programming and controlling the TempLinc

Using a Max-controller

The TempLinc will need to be programmed with a Maxi-Controller

(Smarthome #4020) or an equivalent transmitter capable of send-

ing Housecode and Unit Codes without ON or OFF commands. The

buttons are separated into Addresses and Command functions,

which allow it to send individual commands. Transmitters in which

one button is pressed to turn a load on or off WILL NOT WORK.

When using a Maxi-Controller or an equivalent transmitter, be care-

ful when pressing the buttons. Commands will be ignored if some

commands are not sent in the right sequence. "Fat-Fingering" or accidentally press-

ing the same button twice may prevent the programming from being accepted. This

same transmitter is also used for setting scenes, addresses, and other advanced

features in Smarthome plug-in modules, light switches, and KeypadLinc wall-mount-

ed transmitters.

Windows-based TempLinc Program

Smarthome has created a small Windows-based PC pro-

gram to help program and monitor TempLinc. It is avail-

able as a free download from the TempLinc product

page on Smarthome.com:

http://www.smarthome.com/1625.html

It requires the use of a Serial PowerLinc interface.

The program gives you access to all the features of the

TempLinc. It also includes step-by-step commands to

aid in the programming of the TempLinc.

Third-party programs

As of this manual's publication, we have found that the programs below offer some

support and control for the TempLinc.

• Home Control Assistant (version 4.15 and above)

• HomeSeer Home Automation Software

• Indigo Software for Mac (version 1.3.0 and above)

• Zeus Home Control (version 3.1 and above)

Please note: there are no guarantees that these programs operate flawlessly or that they will continue to

include support for TempLinc. Smarthome make no guarantees or endorsements of these products.

Modes of Operations

The TempLinc can be setup in a variety of different ways depending on the project's

needs. To make programming more of a simple task, decide ahead of time which

mode of operation the TempLinc is to work in. There are eight operation modes that

can be chosen among: Additionally, these modes can measure or report in the

Fahrenheit or Celsius temperature scales.

Report on Change

TempLinc will report the new room temperature whenever a change is detected.

TempLinc will send a house/unit code and preset dim (B15 - Predim6) that corre-

sponds to the current temperature. Refer to Table 2 for a list of temperatures and

their corresponding codes. It will also respond to Status Requests commands

Report on Request

TempLinc will report the room temperature whenever a status request signal is

received. Sending the house/unit code plus the house code/status request (B1 - B

Status Request) to TempLinc will return house/unit code and preset dim of the cur-

rent temperature. Refer to Table 2 for a list of temperatures and their corresponding

codes).

Thermostat (Cooling)

TempLinc will act like a thermostat in cooling mode. Set the temperature set point

by sending a house/unit code combination described in the programming section.

Once the temperature set point is programmed, TempLinc will send out its

house/unit code and house code + "ON" (B1 - BON) if the temperature is higher

than the set point or house code + "OFF" (B1 - BOFF) if the temperature is lower

than the set point.

Cooling Combination 1

This combination combines the report on change feature along with the thermostat

cooling mode feature.

Cooling Combination 2

This combination combines the report on request feature along with the thermostat

cooling mode feature.

Thermostat (Heating)

TempLinc will act like a thermostat in heating mode. Set the temperature set point

by sending a house/unit code combination described in the programming section.

Once the temperature set point is programmed, TempLinc will send out its

house/unit code and house code + "ON" (B1 - BON) if the temperature is lower than

the set point or house code + "OFF" (B1 - BOFF) if the temperature is higher than

the set point.

Heating Combination 1

This combination combines the report of change feature along with the thermostat

heating mode feature.

Heating Combination 2

This combination combines the report of request feature along with the thermostat

heating mode feature.

1625_web.qxd 6/24/2004 1:11 PM Page 6

Programming

With the mode of operation determined, the TempLinc can now be programmed.

Programming will require a PLC transmitter that can send separate unit and function

codes. A Maxi-transmitter, Smarthome #4020 or X10 #SC503 or PHC02 is ideal for

programming the TempLinc. All programmed settings are stored in an EEPROM and

will not be lost if the power is removed or disrupted.

1. Put TempLinc into programming mode by plugging the PowerLinc interface

module into a 120-volt wall receptacle.

2. Within one minute after plugging the PowerLinc into the wall, send the base

house/unit code of the TempLinc three times in a row (D5, D5, D5).

3. Set the operating mode from the table below by sending the house and unit

code (the house code is the same as the one used for the base address)

Code to Send Operation Mode Scale Example

House code + "1" Report on change Fahrenheit D1

House code + "2" Report on request Fahrenheit D2

House code + "3" Thermostat (cooling) Fahrenheit D3

House code + "4" Report on change and thermostat

cooling mode combination Fahrenheit D4

House code + "5" Report on request and thermostat

cooling mode combination Fahrenheit D5

House code + "6" Thermostat (heating) Fahrenheit D6

House code + "7" Report on change and thermostat

heating mode combination Fahrenheit D7

House code + "8" Report on request and thermostat

heating mode combination Fahrenheit D8

House code + "9" Report on change Celsius D9

House code + "10" Report on request Celsius D10

House code + "11" Thermostat (cooling) Celsius D11

House code + "12" Report on change and thermostat

cooling mode combination Celsius D12

House code + "13" Report on request and thermostat

cooling mode combination Celsius D13

House code + "14" Thermostat (heating) Celsius D14

House code + "15" Report on change and thermostat

heating mode combination Celsius D15

House code + "16" Report on request and thermostat

heating mode combination Celsius D16

Table 1

Example:

If the TempLinc was to be put in the report on request mode in Celsius scale and

the desired base address to be D5, send D5, D5, D5 and D10 within one minute

after power-up.

For all modes, other than the thermostat mode, programming is completed and

the TempLinc is ready for use. 7

1625_web.qxd 6/24/2004 1:11 PM Page 7

Programming(continued)

Setting the Set Point in the Thermostat Mode

An additional step is needed for thermostat mode, programming the temperature

set point. After sending the mode command, send a house/unit code combination

that corresponds to the temperature set point at which the TempLinc sends ON or

OFF signals. The first unit code sent is the first digit of the set point temperature

and the second unit code is the second digit. Unit codes 1 through 9 represent dig-

its 1 through 9, for 0 use unit code 10. The set point temperature is limited to a

positive two-digit number between 00 and 99. If the project requires the use of set

points above 99 degrees Fahrenheit, use the TempLinc in the Celsius mode.

Example:

To put the TempLinc in thermostat cooling mode with a set point of 78° in the

Fahrenheit scale and the base address to be L15, send L15, L15, L15, L3, L7, and

L8. The unit codes 7 and 8 will set the temperature to 78°F.

The hysteresis in thermostat mode is 2°F (1°C). In cooling mode, the thermostat

will shut off about 2° lower than the set point. In heating mode, the thermostat will

shut off about 2° higher than the set point.

Any time the TempLinc needs to be reprogrammed or updated, unplug PowerLinc

and leave it unplugged for about 10 seconds. Afterwards, plug the PowerLinc back

in and follow the programming procedure from the beginning.

TempLinc Temperature Reporting

When the TempLinc is in the Report on Change or Report on Request modes, it will

transmit a house/unit code and preset dim level to represent the temperature.

Table 2 shows the temperatures that correspond to each house/unit code and pre-

set dim. The Temperature to PLC Code Translation Table is directly supported by

many home automation systems.

Decoding the Current Temperature Sensed by TempLinc

1. Look at the house and unit code that the TempLinc transmitted. The house

code will match the base house code of the TempLinc and the unit code will

either be 11,12, 13, 14, 15, or 16

2. Select the column that matches the house/unit code sent by the TempLinc

3. Look at the preset dim that was transmitted by TempLinc and match it to the

preset dim value in the left column

4. Once matched, follow that row to the right until house/unit code column is

matched

5. The number that is in the box where the row and column meet is the tempera-

ture
