HTRS230V(30) works mainly as a SLAVE thermostat (group thermostat) which means that it can be controlled by a MASTER thermostat e.g. HTRP230V(50).
MASTER thermostat controls SLAVE thermostat only when SLAVE thermostat is in AUTO mode. Comfort (SUN) and economy (MOON) setpoint
temperatures are set individually on each thermostat but switching between those temperature is based on time schedule taken from HTRP230(50)
thermostat which works like a group controller. Functions such as: setpoint temperature change or frost protection mode are not managed by MASTER
thermostat.
