The Control Unit's Two Methods To Control The Heat Pump - Bosch EHP 6-11 LW User And Installation Manual

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: Control with an outdoor sensor and Control with
an outdoor sensor supplemented with a room sensor.
Control with outdoor sensor
Control with an outdoor sensor is the most common method used by the
control unit to control the heat pump. A sensor is installed on the external
wall of the house. It sends out signals for regulating the heat pump. 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, i.e. it becomes colder; the radiators inside the
house will become warmer.
You determine the temperature of the radiators, in relation to the outdoor
temperature, with the help of a number of settings such as selecting the
heat curve on the control unit. A lower curve gives higher energy savings.
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 central 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
(curves) and ensure the heat pump gives the best possible energy savings.
This control method is used when factors other than the outdoor tempera-
ture infl uence the indoor temperature. Examples include the use of a stove
or fan-assisted radiator or if the house is sensitive to the wind.
It is only the room where the room
sensor is located that can infl uence
regulation of the temperature.
The room sensor infl uence is inhibited
24 hours after using clock setting for
the heating, or any type of external
control of the heat pump.
