Quick Start; What Is Z-Wave; Product Description - Secure SRT321 Manual

Quickstart
This is a Z-Wave Device for Europe. To run this device please insert fresh 2 * AAA
batteries. Please make sure the internal battery is fully charged.
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" to include nodes into the network or "E" to exclude a node from
network. For including the SRT321 as a secondary controller into an existing the Z-Wave
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 "L".

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.
