IntelliTempc T-1000 INSTALLATION INSTRUCTIONS

The IntelliTemp Model T-1000 is designed to continually monitor, and

provide an accurate measurement of the ambient temperature.

The T-1000 allows the user to set high and low temperature parameters.

If the ambient temperature rises above or falls below the set parameter,

the T-1000 will signal a control panel or other monitoring device via Form-

relays. Separate LEDs indicate whether the unit was tripped by tem-

peratures above or below the set parameters.

The Model T-1000 features a bright, three-digit display unit, which can be

set to display the temperature in degrees Fahrenheit or Celsius.

The T-1000 also includes a remote temperature probe, which can be

used to monitor remote locations (up to 100 feet from the display unit)

while keeping the display unit in a convenient viewing location. If local

temperature monitoring is desired (monitoring the ambient temperature

surrounding the display unit), the remote temperature probe can be

installed inside the display unit.

MOUNTING LOCATION

The T-1000 is designed to be wall mounted in an environment where the

temperature ranges between 32° to 140° F (0° to 60° C). To monitor

temperatures beyond this range, use the remote temperature probe.

The temperature probe is designed to monitor a temperature environ-

ment between -40° to 140° F (-40° to 60° C).

The temperature probe comes with 15 feet of two conductor cable and

can be mounted at any desired location. The cable can be lengthened

(up to 100 feet) with any 22 WG twisted pair wire.

IMPORTANT: If it is necessary to install more than one T-1000, make

sure that the serial numbers on the back of each temperature probe and

display unit match.

MOUNTING PROCEDURE

To open the display unit, insert a flat tip screwdriver into the slot on the left

side of the housing and depress the latch. Gently pull apart the front and

rear housing.

Inside the rear housing is the display unit printed circuit board (PCB) and

two mounting holes. Use the rear housing as a template to mark the

mounting holes on the wall. Drill the holes and use two of the screws

provided to secure the display unit to the wall.

NOTE: It is not necessary to remove the PCB from the rear housing

before mounting.

Using the temperature probe remote y:

Use the two remaining screws or double-sided foam tape to mount the

probe at the desired location. The cable between the temperature probe

and the main display unit can be lengthened up to 100 feet using 22

WG twisted pair wire.

Using the temperature probe oca y:

Install the temperature probe PCB onto the display unit PCB as described

below.

1. Push in the latches on the back side of the temperature probe hous-

ing using a flat tip screwdriver. Separate the front and rear housing, see

Figure 2.

2. Gently pull the PCB from the rear housing.

3. Cut off the plastic wire tie securing the cable to the PCB. Cut off the red

and black wires from the back side of the PCB as close as possible.

4. Place the temperature probe PCB into the display unit as shown in

Figure 3. Push the temperature probe PCB onto the pins of the display

unit PCB.

WIRING

Wire as shown in Figure 4, observing the

proper polarity. Do not leave excess wire

inside the unit.

The HIGH and LOW relay outputs can be

combined or used separately (if two moni-

toring loops are available).

To connect the relays to a single monitor-

ing loop, place a wire jumper between the

two common terminals. Connect the re-

maining NC terminals to the monitoring

loop.

To use the temperature probe remotely,

connect the red wire to the (+) input and

the black wire to the (-) input

NOTE: Wire connection to the terminal strip is not necessary for local

temperature monitoring (when the temperature probe PCB is installed

on the display unit PCB).

TEMPERATURE ADJUSTMENT

To set the HIGH and LOW temperature parameters, perform the follow-

ing steps:

1. Remove the front housing.

2. To set the HIGH temperature parameter, remove the horizontal J1

jumper and replace it vertically to cover the middle pin and the pin la-

beled HI, see Figure 5.

3. With a screwdriver, turn the potentiometer labeled HI until the de-

sired high parameter appears on the temperature display.

4. To set the LOW temperature parameter, remove the J1 jumper, and

replace it vertically to cover the middle pin and the pin labeled LO, see

Figure 6.

5. With a screwdriver, turn the potentiometer labeled LO until the de-

sired low parameter appears on the temperature display.

NOTE: The two trip temperatures must be at least 2 degrees Fahrenheit

above and below the ambient temperature.

6. Replace jumper J1 to it original position (horizontal over the middle

and side pins). See Figure 7.

7. Replace the display unit front housing.

TEMPERATURE DISPLAY

The T-1000 is set to display the temperature in degrees Fahrenheit. To

change the display to Celsius:

1. Remove the front housing of the display unit.

2. Remove jumper J2 and place it to over the middle pin and the pin

labeled C.

3. Replace the front housing.

CALIBRATION

The T-1000 is factory calibrated to within ±2° F. In some

applications, the user may wish to alter the displayed tempera-

ture, for example to match other equipment.

To adjust the dispa y, fo ow these steps:

1. llow the T-1000 to stabilize to the ambient temperature.

2. djust R45 (see Figure 1) so the display temperature

matches the reference reading.

3. DO NOT adjust R12 or R5.
