Secure SEC_SRT321 Quick Start Manual

SEC_SRT321
Wall Thermostat with LCD display
Firmware Version : 2.0

Quick Start

A This is a wireless Actor. 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".
Please refer to the chapters below for detailed information about all aspects of the products usage.
What is Z-Wave?
This device is equipped with wireless communication complying to the Z-Wave standard. Z-Wave is the
inte rnational standard for w ire le ss com m unication in smart homes and buildings. It is using the fre que ncy
of 868.42 MHz to realize a very stable and secure communication. Each message is reconfirmed (tw o-w ay
com m unication) and every mains powered node can act as a repeater for other nodes (m e she d ne tw ork) in case
the receiver is not in direct wireless range of the transmitter.
Z-Wave differentiates between Controllers and Slaves. Slaves are either sensors (S) transmitting metered or
measured data or actuators (A) capable to execute an action. Controllers are either static mains powered controllers
(C) also referred to as gateways or mobile battery operated remote controls (R). This results in a number of possible
communication patterns within a Z-Wave network that are partly or completely supported by a specific device.
1. Controllers control actuators
2. Actuators report change of status back to controller
3. Sensors report change of status of measured values to
controller
4. Sensors directly control actuators
5. Actuators control other actuators
6. Remote controls send signals to static controllers to trigger
scenes or other actions
7. Remote controls control other actuators.
There are two different role a controller can have. There is always one single primary controller that is managing the network and
including/excluding devices. The controller may have other functions - like control buttons - as well. All other controllers don't
manage the network itself but can control other devices. They are called secondary controllers. The image also shows that its not
possible to operate a sensor just from a remote control. Sensors only communicate with static controllers.
