- Page 2 GENERAL DESCRIPTION OF THE THERMOSTAT The COMPUTHERM Q8RF (TX) type switched-mode room thermostat is suitable to regulate the overwhelming majority of boilers and air conditioners. It can be used together with the COMPUTHERM Q5RF and Q8RF multi-zone thermostats to complement the two thermostats in the basic package, to increase the number of zones regulated and to control the COMPUTHERM Q1RX wireless (radio-frequency) thermostat-controlled socket.
- Page 3 Boiler Thermostat Reciever 230 V AC, 50 Hz Zone valves 230 V AC, 50 Hz 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.
- Page 4 The effective range of the transmitter incorporated in the thermostat is approximately 50 m in open terrain. This distance may become considerably shorter within a building, especially when a metal structure, reinforced concrete or adobe wall stands in the way of radio waves.
- Page 5 1. LOCATION OF THE DEVICE The thermostats of the COMPUTHERM Q8RF (TX) multi-zone programmable wireless type device can be freely moved in your residence. It is reasonable to locate them in rooms used regularly or for many hours per day so that they are in the direction of natural ventilation in the room but protected from drought or extreme heat (e.g.
- Page 6 The battery compartment is in the inner side of the front panel of the housing. Insert 2 AA alkaline batteries (LR6 type) in accordance with the diagram in the battery compartment. Warning! Good quality alkaline batteries may only be used for this appliance. Carbon-zinc batteries known as durable or long life batteries and chargeable accumulators are not suitable for the operation of this appliance.

- Page 10 The pump protection function can accomplish its task only if the boiler is in working order in the summer, too. It is reasonable to set a low temperature level, e.g. +10°C, on the thermostat for this period, to prevent the boiler from unnecessary start-ups when the weather turns cold temporarily.

Page 11: Programming The Thermostat
the connection points NO and COM of the receiver output relay are closed at temperatures below 21.8 °C (heating is turned on) and 230 V AC is displayed on the output for that zone. The NO and COM conection points are opened at temperatures above 22.2 °C (heating is turned off) and the 230 V AC voltage at its output for that zone is turned off. - Page 12 • The start time of switch PROG is , which cannot be changed, only its temperature can be adjusted. So under the factory default settings, the thermostat performs only one switch (PROG ) every day, which is in effect from until the next day.

- Page 14 of the day, when the family is at work or school, only a lower temperature is needed. As heating up and cooling down usually takes a long time, it is reasonable to set the start time of the switches 0.5-1 hour before the desired time of the modified temperature. The programmability of the thermostat provides a perfect solution for this.
