OTE home climate manager

OCHSNER focused on achieving an intelligent, user friendly concept in its OTE home climate manager for heat pump system control. The OTE offers you optimum convenience, energy efficiency and operational reliability. As well as all the functions for the heat pump, the OTE controller also universally controls DHW heating, cooling mode and swimming pool. Additional heat generators such as boilers and other heat consumers can also be controlled.

Heating and cooling

The heat pump is the only heating system that can also perform cooling. Cooling is achieved via the heating pipes of underfloor and wall heating systems, which absorb the higher temperature indoors and transfer it to the cooler medium (ground or water) via a heat exchanger. Essentially, there are two types of cooling: active and passive – OCHSNER heat pumps offer both – please consult the technical data for the particular type of heat pump.

Noise reduction through whisper quiet operation

The unique and patented whisper quiet operation reduces the sound emissions from OCHSNER horizontal split evaporators to an absolute minimum. You will hardly even notice them working.  In silent mode, which is integrated as standard, the fan speed is reduced according to a fixed proportional function depending on the outside air temperature. This ensures that the system's already extremely low sound emissions in standard operation are reduced even further, for example in summer during DHW or pool heating. Silent mode can be set to four independent, selectable periods. The Super Silent Package is an option for all models in the AIR series and is recommended for especially sensitive areas. The optimised design derived from the aerospace industry reduces noise levels by a further 3 dB(A).
