INDOOR UNIT Aerogor Compact – HydroBox
Following are the key HydroBox components:
Three-way switching valve allows switching from the heating regime to domestic hot water regime. It is the task of this valve to redirect the water to the heating water storage tank or to the domestic hot water storage tank, or vice versa.
Electric circulation heater for bivalent operation. In case of extreme winter conditions, the heat pump no longer generates maximum heating power. Therefore, electric circulation heater is switched on as necessary to provide additional water heating. On average, the heaters operate from 10 to 15 days per year, but only when the temperatures are around -15 °C; such temperatures hardly ever persist throughout the day in our region.
Modern control unit allows diff erent settings for heating, cooling, and domestic hot water heating. The regulation is weather-dependent. The control unit regulates the heat pump and heating system operation according to the outdoor environment temperature and the desired indoor temperature in the user's home. Owing to a special algorithm, the heat pump only generates as much heat as required by the heating system, in any given moment. Regulation of cascade heat pump systems and bivalent systems is also possible.
