Setback input (remote control) (illus. 14)
The unit is equipped with an input for remote control temperature reduction, for example, via a GSM switch.
A closed contact enables centralized control for all the thermostats in the system. When activated, all thermostats
show EXT in the display and the temperature is lowered to + 12 degrees (factory set) for all rooms/zones; the
temperature can be adjusted. NOTE: for more information, please see adjustment/setting of the
