Controllers for Heat Pumps

Air-Water

The programmer is intended for the operation of an air-water heat pump. The purpose of this device is to control the operation of the compressor, the pump, the fan, the heater as well as the pump of the additional heat source. The heat pump contains one heat generator as well as an optional electric heater by means of which heat is collected in the container and heated up to the set temperature. The pump has a coil ready to be connected to an external heat source, e.g. to the CH boiler. The heat pump receives heat from the surrounding air and uses it to heat the water in the container. The air-water heat pump delivers energy stored in air and transfers it onto a higher energy level. Energy collected in natural resources does not have temperature high enough so that it can be directly used for heating.

Functions Performed by the Controller

• Fan control
• Pump operation control
• Control of the compressor’s operation
• Control of the heater’s operation
• Control of the operation of the pump of the additional heat source
• The possibility to connect a room regulator
