GENERAL DESCRIPTION OF THE THERMOSTAT
The
COMPUTHERM
Q8RF
type switched-mode room thermostat is suitable to
regulate the overwhelming majority of boilers and air conditioners. It can
easily be connected to any gas boiler or air conditioning device that has a
double wire connector for a room thermostat, regardless of whether it has a
24V or 230V control circuit.
The basic package of the device includes two thermostats and a receiver unit.
If required, the equipment can be extended by two additional
COMPUTHERM
Q8RF
(TX)
thermostats. The receiver unit receives switching signals from
the thermostats, controls the boiler (or air conditioner) and gives commands
to open/close the heating zone valves (max. 4 zones, loadability of the
zone outputs: 230V AC, max. 1A (0.5A inductive load)) associated with the
thermostats. The zones can operate independently from each other or, in
case of need, all zones can operate at the same time. This way only those
rooms are heated at a given time, where it is required (e.g. the living room
and the bathroom during the day, and the bedroom during the night). Because
there is a wireless (radio-frequency) connection between the thermostats and
the receiver, no cable is required between the thermostats and the boiler. The
installation and connection of the receiver unit is described in
Section 9
.
The device can be programmed according to customer-specific requirements
so that the heating/cooling system heats/cools your residence or office to
the required temperature at the dates and times specified by you, to reduce
energy costs while maintaining comfort. Separate temperature programs can
be prepared for each day of the week. For each day, beside 1 fixed switching
time
(
PROG
)
, 6 adjustable switching times
(
PROG
‒
PROG
)
can be set (at
10-minute intervals) and a different temperature (in 0.5°C increments) can be
assigned to all 7 switching times.
To increase the lifetime of the batteries, the thermostat will not transmit signals
continuously. Instead it will repeatedly transmit the actual signal every 8 minutes.
Therefore, the regulation of the heating or cooling will continue even after a
blackout.
