TFS Central Control Unit Compatible and Optional for RF Aeroflow Units
The central radio transmitter is used to program the thermostat setting and time programming for radiators fitted with the radio frequency remote receiver. These are signified by the RF suffix.
The central controller is a room thermostat and 7 day 24 hour programming system.
Like a traditional central heating system, the temperature is sensed at a central point, usually the hallway and the radiators respond accordingly.
