Page 3: Intended Use
1. Intended Use The radio-controlled radiator thermostat set comprises of three components: • the FHT 80b Wall Thermostat (heating control), • the FHT8V Actuator (valve operating mechanism), and • the FHT 80TF Door / Window Contact Sensor (sold separately). The system is used for temperature control in individual rooms in which the heat that dissipates from radiators is controlled by reducing the flow of hot water in the heating system. -

2. Description and Function Compared with simple mechanical thermostats (a.k.a. TRVs), the radio- controlled radiator thermostat systems have a number of advantages: • the split between the radiator-mounted valve operating mechanisms and the freely positionable operation and control units (e.g. the FHT 80b heating control which is part of the scope of supply) makes it possible to perform settings easily. - Page 5 Changes (‘Window open’ or ‘Window closed’) are signaled to the heating control within a time period of about 1 minute. This allows the heating control to adjust the temperature after an average of 30 seconds, in order to save energy when, for example, a room is aired. 2.2.Safety code The radio signal is protected by a safety code consisting of two parts.
- Page 6 2.3.Information on the range The transmission power is less than 10mW, much below that of a mobile phone which may have a transmission power 200 times as great. Adverse effects on sensitive people and animals are not to be expected. The wireless radiator thermostat system uses the 868MHz range, which is also used by other radio services.

Setting the comfort temperature, lowering temperature and the ‘Window open’ temperature When the automatic mode has been activated and switching between the lowering temperature and the comfort temperature is performed automatically, a bar in the lower part of the display indicates the time of day at which the temperature will be set to the comfort temperature. - Page 16 The heating control now returns to the normal operating mode. 8.2.Setting / changing the weekly profile The time for automatic switching between the comfort temperature and the lowering temperature can be set separately for each day of the week. That way you may adapt the desired room temperature to your individual lifestyle.

Each part of the code comprises 100 setting options. This means that a total of 10,000 different security codes are available. To ensure communication between the FHT 80b heating control and the FHT 8V valve operating mechanism(s) the same security code has to be set for all the devices in a room.
