- Page 2 Hungary. It can be used together with the COMPUTHERM Q5RF or 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 the adjusted temperature, respectively, and contributes to reduce energy costs while maintaining comfort. In cooling mode it switches exactly the opposite way. 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.
- Page 4 The portability of the thermostat offers the following advantages: • no need to lay a cable, which is especially advantageous when old buildings are being modernized, • the optimal location of the device can be selected during operation, • it is also advantageous when you intend to locate the thermostat in different rooms in the course of the day (e.g.
- Page 5 1. LOCATION OF THE DEVICE The thermostat of the COMPUTHERM Q5RF (TX) type device can be freely moved in your residence. It is reasonable to locate it in a room used regularly or for many hours per day so that it is in the direction of natural ventilation in the room but protected from drought or extreme heat (e.g.

Warning! 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. Icon appearing on the display to indicate low battery voltage warns reliably that the batteries should be replaced only when alkaline batteries are used. - Page 8 With factory default settings the jumper is located on the central and uppermost pins, in which case the display shows the currently meas- ured room temperature value, while the notice “ROOM” appears in the bottom right corner of the display. In this case, the adjusted tempera- ture is visible only during the adjustment process, for approximately 7 seconds after the last button has been pushed.
- Page 9 The heat loss of the room (building) does not depend on the switching sensitivity. If higher comfort is needed, the switching sensitivity should be set so that it provides a steadier room temperature. On the other hand, please also take into account that the boiler should not switch on and off mul- tiple times in an hour’s time except at low outside temperatures (e.g.

3.5 Synchronising the Thermostat and the Receiver Unit In order to have a safe, reliable and trouble-free wireless (radio-frequency) connection, both the thermostat and the receiver unit have their own safety codes. After installing the receiver unit, the two units should be synchronised by pressing the “LEARN”... - Page 12 positions of the switch a different tempera- ture can be set between 5 °C and 40 °C, in steps of 0.5 °C. For energy efficiency it is recommended that the comfort tem- perature is only used those times, when the room or building is in use, because every 1 °C decrease of temperature saves approximately 6% energy during a heating season.
- Page 13 continuously (the change in values is accelerated), the de- sired temperature to be maintained at the place where the thermostat has been installed can be set in steps of 0.5 °C. • Approximately 7 seconds after setting the room tempera- ture to be maintained, the device automatically switches to normal mode.

6. BATTERY REPLACEMENT The average lifetime of the batteries is 1 year. The icon alter- nately replacing the temperature value on the display indicates low battery voltage. Replace the batteries whenever the icon indicating low battery voltage appears on the display (see Section 2). - Page 16 7.1 COMPUTHERM Q5RF (TX) - COMPUTHERM Q5RF / Q8RF When you wish to use thermostat COMPUTHERM Q5RF (TX) in or- der to extend COMPUTHERM Q5RF / Q8RF multi-zone device then carry out synchronization according to the instructions for use of thermostat COMPUTHERM Q5RF / Q8RF.

- Page 19 plug switches on and off, respectively. When the receiver unit fails to receive signals sent by the thermostat, then the receiver unit is outside the transmission distance of the wireless (radio-frequency) transmitter, thus they have to be placed closer to each other. ATTENTION! If the two parts of the device can only be placed on the edge of the wireless (radio-frequency) range or out of it (due to the floor-plan of the house or the shading effect of its structure),...
