Heating
The heat pump produces heating water directly into the building's heating network. Automatic adjustment
determines the setpoint for the supply water from the heating circuit based on the set heating curve and
the outdoor temperature measurement.
The controller uses the supply water setpoint to determine the heat pump setpoint, based on which the
heat pump produces heating energy and keeps the temperature of the supply water at the setpoint. The
room temperature sensor also affects the setpoint.
In order for the heat pump to operate at maximum efficiency, the heating system and the brine circuit
must be under ideal conditions. The difference between the heating system's output and return
temperatures must be 5–8 °C, and the difference between the collector's output and return temperatures
must be 3–4 °C. If the temperature differences deviate from these values, the efficiency will decrease,
along with the savings. The heat pump controller controls the charge and source pumps to achieve the
desired temperature difference.
Factory settings:
•
Heating temperature difference: 5 °C
•
Preparation of domestic water: pressure control
•
Collector temperature difference: 3.5 °C
3.4 Tips for making savings
The heat pump is intended to generate the desired heat and domestic water. The system attempts to
meet these desires by all available means within the limits of the setpoints.
Important factors affecting energy consumption are the indoor temperature, the domestic hot water
consumption, the temperature of the domestic hot water, the quality of the house's insulation, and the
desired level of comfort.
Keep the aforementioned factors in mind when changing the device's settings.
Underfloor heating and radiator thermostats can have a negative impact on
energy consumption. They reduce the flow rate in the heating system, and the
heat pump compensates for this by raising the temperature of the network. This
affects the device's operation and consumes more electrical energy.
Thermostats are only intended for adjustments due to "free heat" (the sun, people,
fireplaces).
3.5 Heat pump's components and sensors
Functional and measuring thermal sensors are installed in the heat pump. The sensors are attached to
components and insulated from external heat. Some of the sensors are located in the compressor unit
module.
