Group 2 - Central heating node controlled 

by the SCS311 or SCS317 will determine 
how best to communicate with the device. If 
thermostat mode Heat Mode is supported 
the control message will be sent as 
Thermostat Set HEAT and Thermostat 
mode set Off, otherwise the device will be 
controlled by Basic set On and Off 
commands.

Up to four nodes can be associated to 

Association Group 2.

Configuration 

Parameters (sequential order)

Basic

The Basic command class is mapped to the 

thermostat set point, with HEAT as the 
parameter.

Following parameters are used for SET:

0x00 – Enables energy saving mode, 

temporarily overrides the set temperature 
with the standby temperature.

0xFF – Set comfort mode, temporarily 

regulates the room temperature to 21 
degrees.

GET command provides the following 

responses:

0x00 – Energy saving mode enabled

0xFF – Energy saving mode disabled

Basic SET commands will be sent to control 

devices in Association Group 2 if they do 
not support the appropriate modes in the 
thermostat mode command class.
