Controllers for Heat Pumps

Air-WaterThe EU-51 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 and the pump of the additional heat source.

The heat pump contains one heat generator and, optionally, an electric heater by means of which heat is collected in the container and heated 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. The temperature of the energy collected in the natural resources is too low for it to 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

Controller’s Equipment:

• Graphic LCD display
• Tank temperature sensor (DHW)
• Unit control temperature sensor
• Temperature sensor for the additional heat source
• External temperature sensor
• A pressure switch for operation of high pressure
