 HEATING
In this menu item you can set the temperatures to be targeted by
the heat pump manager if the external voltage signal for heating
mode is present.
Note
If a voltage of 2 to 9V is present, the preset temperatures
are interpolated accordingly.
 PRESET TEMPERATURE 1V
 Set here the temperature that should be targeted by the heat
pump manager if a voltage of 1V is present at inputX1.15.
 PRESET TEMPERATURE 10V
 Set here the temperature that should be targeted by the heat
pump manager if a voltage of 10V is present at inputX 1.15.
 COOLING
In this menu item you can set the temperatures to be targeted by
the heat pump manager if the external voltage signal for cooling
mode is present.
Note
If a voltage of 2 to 9V is present, the preset temperatures
are interpolated accordingly.
 PRESET TEMPERATURE 1V
 Set here the temperature that should be targeted by the heat
pump manager if a voltage of 1V is present at inputX1.15.
 PRESET TEMPERATURE 10V
 Set here the temperature that should be targeted by the heat
pump manager if a voltage of 10V is present at inputX 1.15.
 OUTPUT X1.16/X1.17
In this menu item you can adjust the settings for the pump con-
nected to the output.

A Setting range
The pump speed is controlled in proportion to the PWM input
signal. The pump stops if there is a cable break.
 Set this parameter to ON if you connect a pump for solar
thermal energy.
 Observe the operating instructions of the pump
manufacturer.

A Setting range
The pump speed is controlled in inverse proportion to the PWM
input signal. If there is a cable break, the pump runs at maximum
speed.
 Set this parameter to ON if you connect a heating circuit
pump.
 Observe the operating instructions of the pump
manufacturer.
 0-10 V
 Set this parameter to ON if you use a pump that is controlled
by a 0-10V voltage signal.
 OUTPUT
 Select here the pump that is connected to the output.
You have the following options:
- Buffer charging pump (BUFFER CHARGING PUMP 1 / 2)
- Heating circuit pump (HK PUMP 1 / 2 / 3)
- DHW charging pump (DHW CHARGING PUMP)
- Source pump (SOURCE PUMP)
- CHARGING PUMP CONTROL HEATING
- CHARGING PUMP CONTROL DHW
 OUTPUT
In this menu item, you can assign a signal strength for pulse width
modulation to the connected pump. The signal is used to specify
the flow rate, output or set speed.
 Please also note the information on flow rate (see the operat-
ing instructions for the pump and the chapter “Specification/
Data table” in the operating and installation instructions for
the heat pump).
