3 TEMPERATURE CONTROL
The heating and cooling devices are managed based on the temperature measured by the room probe, compared against the temperature set
point.
• Programmable parameters: temperature set point, proportional band (this may be different for heating and cooling), dead zone,
freecooling start and end point as a percentage of the proportional band.
• Fixed parameters: compressor and heater on/off points in the proportional band.
