What is Z-Wave?
Z-Wave is the international wireless protocol for communication in the Smart Home. This
device is suited for use in the region mentioned in the Quickstart section. (For more
information about frequency regulations please refer to the frequency coverage overview at
Sigma Designs Website ).
Z-Wave ensures a reliable communication by
reconfirming every message (two-way
communication) and every mains powered
node can act as a repeater for other nodes
(meshed network) in case the receiver is not
in direct wireless range of the transmitter.
This device and every other certified Z-Wave
device can be used together with any other
certified Z-Wave device regardless of brand
and origin as long as both are suited for the same frequency range.
If a device supports secure communication it will communicate with other devices secure as
long as this device provides the same or a higher level of security. Otherwise it will
automatically turn into a lower level of security to maintain backward compatibility.

Product Description
The SRT321 is a battery operated wall thermostat. Using a big wheel on the device the user
can preset the desired target temperature in the room. By verifying the target temperature with
the measured real temperature closed to the device the unit decides how to operate a
wirelessly attached power switch that is attached to the heater. In parallel a central gateway of
Z-Wave control software can set the target temperature using Z-Wave. This enables to realize
a time scheduled zone heating. The thermostat itself does not have any internal timers but
executes the wireless settings (COMMAND CLASS THERMOSTAT_SETPOINT) and the
local setup.
Prepare for Installation / Reset
Please read the user manual before installing the product.
In order to include (add) a Z-Wave device to a network it must be in factory default state.
Please make sure to reset the device into factory default. You can do this by performing an
Exclusion operation as described below in the manual. Every Z-Wave controller is able to
perform this operation however it is recommended to use the primary controller of the
previous network to make sure the very device is excluded properly from this network.
Reset to factory default
This device also allows to be reset without any involvement of a Z-Wave controller. This
procedure should only be used when the primary controller is inoperable.
For reseting the device do the following steps: Set DIL switch 1 on the back of the unit to
"ON" position, scroll through the function menu by rotating the dial, select "P". Confirm the
procedure by double tapping the dial. Now your device is reset to factory defaults.
Safety Warning for Batteries
The product contains batteries. Please remove the batteries when the device is not used. Do
not mix batteries of different charging level or different brands.
Installation
Choose a suitable mounting position in your room for installing the device. The SRT321
should be mounted on an internal wall approximately 1.5 metres from floor level using the
wall plate provided and should be in a position away from draughts, direct heat and sunlight.
Ensure that there will be enough space to allow easy access to the two retaining screws
located at the base of the wall plate. Avoid installing the thermostat against or behind any
large metal surfaces which could interfere with the radio signals.
Offer the plate to the wall in the position where the SRT321 is to be mounted and mark the
fixing positions through the slots in the wall plate. Drill and plug the wall, then secure the
plate into position. The slots in the wall plate will compensate for any misalignment of the
fixings. Undo the screws of the base of the thermostat and swing it away from the wallplate.
Place the 2 x AAA batteries correctly into the battery compartment. Complete the installation
by swinging the room thermostat into position by engaging with the lugs at the top of the wall
plate before pushing it carefully into its plug-in terminal block. Tighten the 2 captive screws
on the underside of the unit.
Inclusion/Exclusion
On factory default the device does not belong to any Z-Wave network. The device needs to be
added to an existing wireless network to communicate with the devices of this network.
This process is called Inclusion.
Devices can also be removed from a network. This process is called Exclusion. Both
processes are initiated by the primary controller of the Z-Wave network. This controller is
turned into exclusion respective inclusion mode. Inclusion and Exclusion is then performed
doing a special manual action right on the device.
Inclusion
For including the thermostat as a secondary controller into an existing the Z-Wave network do
the following steps: Bring your primary controller into inclusion mode. Set DIL switch 1 on
the back of the unit to "ON" position, scroll through the function menu by rotating the dial,
select "L". Once the character starts flashing the installer has 60 sec to activate the 3rd party
unit, once the 3rd party unit has been activated the process must be completed within 240 sec
or the thermostat will timeout.
Exclusion
For excluding the thermostat as a secondary controller into an existing the Z-Wave network
do the following steps: Bring your primary controller into inclusion mode. Set DIL switch 1
on the back of the unit to "ON" position, scroll through the function menu by rotating the dial,
select "L". Once the character starts flashing the installer has 60 sec to activate the 3rd party
unit, once the 3rd party unit has been activated the process must be completed within 240 sec
or the thermostat will timeout.
Product Usage
Thermostats using TPI (Time Proportional Integral) control algorithms will reduce the
temperature swing that normally occurs when using traditional bellows or thermally operated
thermostats. As a consequence, a TPI regulating thermostat will maintain the comfort level far
more efficiently than any traditional thermostat.
When used with a condensing boiler, the TPI thermostat will help to save energy as the
control algorithm allows the boiler to operate in condensing mode more consistently
compared to older types of thermostat.
DIL switch numbers 7 and 8 should be set as diagram opposite.
For Gas boilers set the TPI setting to 6 cycles per hour. (Default setting)
For Oil boilers set the TPI setting to 3 cycles per hour.
For Electric heating set the TPI setting to 12 cycles per hour.
The DIL switch 1 has to be set to position "ON" for configuration mode. To go bacj to
normal mode switch the DIL switch 1 to the "OFF" position.
Turn the rotating dial on the front within configuration mode and select the desired function
by pushing the dial once:

Node Information Frame
The Node Information Frame (NIF) is the business card of a Z-Wave device. It contains
information about the device type and the technical capabilities. The inclusion and exclusion
of the device is confirmed by sending out a Node Information Frame. Beside this it may be
needed for certain network operations to send out a Node Information Frame. To issue a NIF
execute the following action:
To send out a Node Information Frame do the following steps: Set DIL switch 1 on the back
of the unit to
Communication to a Sleeping device (Wakeup)
This device is battery operated and turned into deep sleep state most of the time to save
battery life time. Communication with the device is limited. In order to communicate with the
device, a static controller C is needed in the network. This controller will maintain a mailbox
for the battery operated devices and store commands that can not be received during deep
sleep state. Without such a controller, communication may become impossible and/or the
battery life time is significantly decreased.
This device will wakeup regularly and announce the wakeup state by sending out a so called
Wakeup Notification. The controller can then empty the mailbox. Therefore, the device needs
to be configured with the desired wakeup interval and the node ID of the controller. If the
device was included by a static controller this controller will usually perform all necessary
configurations. The wakeup interval is a tradeoff between maximal battery life time and the
desired responses of the device. To wakeup the device please perform the following action:
To wake up the device do the following steps: Set DIL switch 1 on the back of the unit to
"ON" position, and select one of the konfiguration functions by pushing the rotating dial once.
Quick trouble shooting
Here are a few hints for network installation if things dont work as expected.
1. Make sure a device is in factory reset state before including. In doubt exclude before
include.
2. If inclusion still fails, check if both devices use the same frequency.
3. Remove all dead devices from associations. Otherwise you will see severe delays.
4. Never use sleeping battery devices without a central controller.
5. Dont poll FLIRS devices.
6. Make sure to have enough mains powered device to benefit from the meshing
Association - one device controls an other device
Z-Wave devices control other Z-Wave devices. The relationship between one device
controlling another device is called association. In order to control a different device, the
controlling device needs to maintain a list of devices that will receive controlling commands.
These lists are called association groups and they are always related to certain events (e.g.
button pressed, sensor triggers, ...). In case the event happens all devices stored in the
respective association group will receive the same wireless command wireless command,
typically a 'Basic Set' Command.

Special Operations as Z-Wave Controller
As long as this device is not included into a Z-Wave network of a different controller it is able
to manage its own Z-Wave network as primary controller. As a primary controller the device
can include and exclude other devices in its own network, manage associations, and
reorganize the network in case of problems. The following controller functions are supported:
Inclusion of other devices
Communication between two Z-Wave devices only works if both belong to the same wireless
network. Joining a network is called inclusion and is initiated by a controller. The controller
needs to be turned into the inclusion mode. Once in this inclusion mode the other device
needs to confirm the inclusion - typically by pressing a button.
If current primary controller in your network is in special SIS mode this and any other
secondary controller can also include and exclude devices.
To become primary a contoller have to be resetted and then include a device.
For Inclusion of Z-Wave devices into the thermostats network do the following steps: Set DIL
switch 1 on the back of the unit to "ON" position, scroll through the function menu by
rotating the dial, select "I". Press the dedicated button on the target device to include it. Once
the character starts flashing the installer has 60 sec to activate the 3rd party unit, once the 3rd
party unit has been activated the process must be completed within 240 sec or the thermostat
will timeout.
Exclusion of other devices
The primary controller can exclude devices from the Z-Wave network. During exclusion the
relationship between the device and the network of this controller is terminated. No
communication between the device and other devices still in the network can happen after a
successful exclusion. The controller needs to be turned into the exclusion mode. Once in this
exclusion mode the other device needs to confirm the exclusion - typically by pressing a
button.
Attention: Removing a device from the network means that it is turned back into factory
default status. This process can also exclude devices from it's previous network.
For Exclusion of Z-Wave devices from the thermostats network do the following steps: Set
DIL switch 1 on the back of the unit to "ON" position, scroll through the function menu by
rotating the dial, select "E". Press the dedicated button on the target device to exclude it. Once
the character starts flashing the installer has 60 sec to activate the 3rd party unit, once the 3rd
party unit has been activated the process must be completed within 240 sec or the thermostat
will timeout.
Shift of Primary Controller Role
The device can hand over its primary role to another controller and become secondary
controller.
Set DIL switch 1 on the back of the unit to "ON" position, scroll through the function menu
by rotating the dial, select "C". The thermostat will become the secondary controller.
Management of Association in the controller
To assign associations with devices you wish to control with the thermostat do the following
steps: Set DIL switch 1 on the back of the unit to "ON" position, scroll through the function
menu by rotating the dial, select "A". Press the dedicated button on the target device you wish
to control.
To disassociate an association do the following steps: Set DIL switch 1 on the back of the unit
to "ON" position, scroll through the function menu by rotating the dial, select "D". Press the
dedicated button on the target device you wish to disassociate.
Configuration Parameters
Z-Wave products are supposed to work out of the box after inclusion, however certain
configuration can adapt the function better to user needs or unlock further enhanced features.
IMPORTANT: Controllers may only allow configuring signed values. In order to set values
in the range 128 ... 255 the value sent in the application shall be the desired value minus 256.
For example: To set a parameter to 200 it may be needed to set a value of 200 minus 256 =
minus 56. In case of a two byte value the same logic applies: Values greater than 32768 may
needed to be given as negative values too.
