is the heat balance of the heating system. Production of heat is regulated acc. to
a calculated heat demand value. This value is determined by comparing the actual supply
line temperature with its calculated (setpoint) value. The difference between the two values
is multiplied by the time during which the difference is active. The resul- ting value is referred
to as the integral. The integral value is automatically established when heat is being
produced. The value can be viewed in the sub-menu TEMPERATURE.

the condenser, the refrigerant releases its heat energy to the heating circuit. (See ”Heat

CURVE value will be adjusted on the control panel. The value indicates the temperature
of the water distributed to the radiators (supply line temperautre) at an outside air
temperature of 0°C.
cuit in the heat pump filled with refrigerant that by evaporation, compression, and
condensation absorbs heat energy from the sytem circuit and releases it to the
Heating circuit.
Radiator Heating element
Con trol
he control computer regulates the whole installation. All system settings and computer
temperature changes are stored and registered in the computer. Settings are adjusted
ia the graphic display on the control panel.
Heating circuit
he heating circuit receives heat energy from the refrigerant circuit and carries it to the water
heater or radiator/ floor coil systems. (See further”Heat Pump Principle” on p.4).
Heat curve
he heat curve is the control computer’s instrument for determining the required supply line
temperature of the heating system. Indoor temperature will be adjusted by adjustment of the

Sensor disconnected; Sensor was
defective.
Check the connections, the wire of sensor, or change the sensor.
Under 25 °C, the resistance of sensor should be 5K
BRINE IN TEMP
Brine in temperature sensor
error; All operation stopped.
Sensor disconnected; Sensor was
defective.
Check the connections, the wire of sensor, or change the sensor.
Under 25 °C, the resistance of sensor should be 5K
