Page 3: 1. 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...
Page 4: Description And Function
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 ...

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 signa...
