How It Works
System X overdoor heaters provide a warm airstream across doorways and entrances. They are particularly well-suited to shops.
A system will include a controller and up to 12 individual heaters. The control daisy chain is connected using Cat5 cables ensuring the quickest possible installation time. Power is introduced to each heater individually with the controller taking its power from the first heater in the chain.
A unique feature of System X is that any style of heater from the range can be incorporated into a control daisy chain. For example, an overdoor heater could be added to a ceiling grid heater system. Heaters can be connected in any combination and any sequence.
