1.  What can the T70RF thermostat be used for?

-The room thermostat COMPUTHERM T70RF was specially developed for the control of heating and cooling systems. It is also suitable for controlling electrical and electronic devices, which can be switched on and off by removing and switching the power supply unit back on.

2.  Which battery can the thermostat be used with?

- The device is operated with 2 1.5 V alkaline batteries (type LR03; size AAA) (ex works). Use only high quality alkaline batteries in the device. Other batteries that are described as long-life or long-life (e.g. conventional carbon-zinc batteries), discharged batteries or the use of rechargeable batteries is not suitable for the operation of the device.

3.  Where should the thermostat and receiver be placed?

- It is advisable to place the thermostat transmitter in a room with regular or long-term use so that it follows the natural movement of the room, but is not exposed to drafts or extreme heat (e.g. solar radiation, refrigerator, chimney), etc. ). Do not use in damp, chemically aggressive or dusty environments. Its optimal location is 0.75-1.5 m above the ground. The device can be easily attached to the base and can then be placed on any horizontal surface (e.g. table, shelf, chest of drawers) or even mounted on the wall thanks to the screw holes on the back.

-The receiver of the COMPUTHERM T70RF thermostat should be installed near the boiler in a place protected from moisture, dust, chemicals and heat. When choosing the location of the receiver, also take into account that the propagation of radio waves is caused by heavy metal objects (e.g. boiler, buffer storage, etc.) or that metal structures can be adversely affected. If possible, we recommend installing the receiver at a distance of at least 1-2 m and at a height of 1.5-2 m from the boiler and other large metal structures in order to ensure interference-free radio communication. We recommend that you check the reliability of the radio connection at the selected location before installing the receiver. Do not install the receiver under the boiler cover or in the immediate vicinity of hot pipes or pumps, as this can damage the components and endanger the radio link (radio frequency). It is also recommended to supply the receiver with mains power from a different socket than the boiler (if possible from a different phase) and never to lead it from the boiler to the receiver. In order to avoid an electric shock, connect the receiver to a boiler, a professional must employ !!

4th  Can I use several T70RFs in one house at the same time?

-Yes .  Each thermostat and the associated receiver have their own security code, which guarantees the safe and trouble-free operation of the devices. Each receiver only receives signals from a thermostat with the same security code. As a result, essentially any number of devices can be used in close proximity to one another without causing problems with device communication.

5.  What causes an insecure wireless connection?

-This could be for several reasons. The most common causes are:

-Use of an unsuitable battery (e.g. dead or non-alkaline battery)
- Too great a distance or too many obstacles (e.g. more reinforced concrete slabs, more thick walls, etc.)
- Incorrect placement of the thermostat transmitter or receiver between transmitter and receiver (details   see above)
-Using other high frequency devices with a higher frequency than usual (such as some baby monitors   or wireless headphones)
-other external interference (e.g. high-performance antenna on the roof or nearby)

6th  How do the devices continue to work after the power failure?

-After the power supply has been restored, the receiver output is initially switched off. However, since the transmitter repeats its current switching command every 10 minutes, the heating / cooling system control returns to the previously set mode no later than 10 minutes after the power failure.

7th  What should I do if the recipient is not communicating securely with the sender?

There can be several reasons why the sender does not communicate with the receiver or only communicates insecurely. To fix this problem, we recommend that you try the following suggestions:

-Replace the batteries in the transmitter. Make sure you only have good quality alkaline batteries   in the  Device can be used. Other batteries labeled long-life or long-life (ex.   B. conventional carbon-zinc batteries), empty batteries or the use of batteries is not suitable for the operation of the device.
-Make sure the two units are aligned. If the two devices are not communicating close together, they may have to be adjusted as described in the operating instructions.
-Bring the thermostat transmitter and receiver closer together if you think they are too far apart.
-Check that the thermostat transmitter and receiver are installed as described. If not, move them as described (see above for details).
-Avoid using other high frequency devices (radios) such as B. some baby monitors or wireless headphones nearby.

8th.   Can the thermostat be synchronized with multiple receivers?

-Yes.   The COMPUTHERM T32RF wireless thermostats can control several receivers at the same time. The coupling can be carried out as described in the instructions with the addition that, in the first step, all receivers must be set to alignment mode.
