The load conditions for one or both compressors achieve the desired temperature setting so that it changes to suit demand. Only one compressor is needed for low demand, and both for high. Up to four indoor units can be run off one outdoor unit.
Outdoor units are cooling only and cooling/heating. Outputs range from 4.2 to 8.7 kW for cooling and 4.2 to 9.6 kW for heating.
All Multi M indoor units have a hand-held infra-red remote controller for temperature settings, mode selection, air circulation and fan operation.
Other control options include a hard-wired central unit that can control all the indoor units.
