An exclamation mark in a triangle indicates important information in these operating instructions which must be observed without fail. The ‘hand’ ...
Page 7: 4. General Information
7 4. General information the radio-controlled radiator thermostat system has a number of advantages compared with simple mechanical thermostats: • the system is separated into radiator-mounted valve operating mechanisms and freely positionable operation and control units (the ‘fht80b-3’ heating cont...
Page 8: B) Security Code
8 changes (‘window open’ or ‘window closed’) are signalled 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 a room is aired, for example. B) security code the radio si...
