the heat pump and provide the control unit with information about the

current room temperature. The signal affects the flow temperature.

For example, it falls when the room controller indicates a higher

temperature than the one set. Room controllers are used when factors

other than the outdoor temperature influence the indoor temperature

of the house. For example, this can be when a stove or fan-assisted

radiator is used in the house, or if the house is sensitive to the wind or

exposed to direct sunlight.

8.3 TIME CONTROL FOR HEATING

• Program control; the control unit offers four fixed and two individual

programs for clock setting of day/time.

• Holiday; the control unit has a program for holiday mode, which

means that during the selected period the room temperature changes

to a lower or higher level. The program also allows switching off hot

water production.

• External control; the control unit can make settings for external

control, which means that the preselected function is performed

when the control unit senses an input signal.

8.4 OPERATING MODES

• With electrical additional heat; the additional electrical heater is

used to supplement both DHW and CH when required temperature is

not fulfilled.

• With mixed additional heat (option); the additional boiler option is

used to supplement both DHW and CH when required temperature is

not fulfilled.

9 ENERGY METERING

Energy metering in the heat pump is an approximation based on the sum

of the nominal emitted output during the relevant metering period. The

calculation requires for example that the heat pump is correctly

installed, and that the flow and  temperatures on the hot and cold sides

are adjusted as recommended. The value should therefore be regarded

as an estimate of the actual emitted output. The margin of error in the

calculation is normally put at 5-10%.

In addition, the energy output is affected by the outdoor temperature,

the settings for the thermostat and room controls and heat pump usage.

Ventilation, indoor temperature and hot water demand can play a

decisive role.

It is only the room where the room controller is located

that can influence the temperature of the relevant

heating circuit.

The Multi module accessory is required for mixed

additional heat and hot water electric heater.
