Description
The Helo RA 18 Midi is a compact control unit that can be installed inside the sauna room itself, putting the controls within easy reach of the bather. It sets an adjustable temperature, a heating time of up to 6 hours and a pre-set start of up to 23 hours ahead, and its display shows both the set and the actual temperature; it also switches the sauna lighting. The Midi is compatible with the Helo Roxx, Cava, Rocher, Himalaya and Pikkutonttu heaters in their DE versions only, so check your heater’s model code before ordering. This listing is for the control unit only: the heater is sold separately.
