The control unit’s two methods to control

the heat pump

The control unit uses two different methods to control the heat pump.

These two methods are A or B, as below:

A: Control with outdoor sensor

A sensor is installed outside on a North facing wall of the house. Control

with an outdoor sensor means that the heat pump automatically regulates

the heating in the house depending on the outdoor temperature. If the

outdoor temperature drops, the radiators/underﬂ oor heating inside the

house will become warmer.

The user determines the response from the heat pump in relation to

the outdoor temperature, with the help of a number of settings such as

selecting the heat curve on the control unit. Further explanation is given

later in this manual.

B: Control with outdoor sensor supplemented with

room sensor

Control with an outdoor sensor supplemented with a room sensor means

that you also place a sensor in a reference position inside the house. This is

connected to the heat pump and provides the control unit with information

about the room temperature. The signals affect the control unit’s settings

(heat curves) and ensure the heat pump gives the best possible energy

savings.

It is only the room where the room

sensor is located that can inﬂ uence

regulation of the temperature.

Note

Rego 637W Control unit

Note

The room sensor inﬂ uence is inhibited

2 hours after using clock setting for

the heating, or any type of external

control of the heat pump.
