Electric supplementary heat register (EH) (Option)

The EH electric supplementary heat register enables constant control of the supply air temperature and thus increases comfort. The EN electric supplementary heat register is pre-wired with a control unit integrated in the Reco-Boxx in the RLT unit.
It is possible to increase the supply air temperature by around 10 Kelvin compared to the temperature after the air heat exchanger.
Attention: If the electric heat register overheats (z.B "heating function on" when the system is open and air is not flowing completely through the register), a safety temperature limiter (STL) is triggered directly at the heat register and switches it off. The register is reactivated by pressing the safety button on the STL until it engages.
It is essential to switch off the mains circuits at the main switch beforehand, as the heat registers are operated at 400 V!
