The wireless thermostat set COMPUTHERM Q8RF

with switching operation is for regulation

by the overwhelming majority of commercially available boiler and air conditioning systems
net. It can simply be connected to any gas boiler with a two-line room thermostat
connection point or air conditioning can be connected, regardless of whether this is via 24V

or 230V control circuit.
The basic package of the device includes two thermostats and a receiver.
If necessary, the system can be expanded to include two more thermostats.
The receiver receives the switching signals from the thermostats and controls the boiler

(or the air conditioning) and commands the opening / closing of the
heating zone valves belonging to mostats (max. 4 zones, load capacity per zone

230V AC, maximum 1A (0.5A inductive). By zoning the heating system
tems, the individual zones can be operated separately or even at the same time
the. This enables only the rooms to be heated

where you are (e.g. living room and bathroom during the day, at night

Bedroom). The connection between the thermostat and the receiver
secured wirelessly (with radio frequency), so there is no line between the

Erect thermostats and the boiler. Installation, connection and
of the receiver and its coordination with the thermostats, see Chapter 9.
