Heat pump manager 7.5
NOTE
Only use pure water in the heating circuit (no mixtures, no antifreeze)!
The control PCB of the electronics module requires its own volt-
age supply, which can be tapped either from the mains power
supply or from the terminal strip (mains L/N/PE ~230 VAC) of the
heat pump manager.
A signal line which transmits the pulse must be connected be-
tween terminals X2/1/2 of the electronics module and the heat
pump manager (N1).
Terminal diagram:
Compact heat pumps
With heat pumps with integrated heating components for an un-
mixed heating circuit (compact heat pump), the installation of the
thermal energy meter within the heat pump (upstream of the
branch for domestic hot water preparation) is not possible. In this
case the thermal energy meter for the measuring of the heating
operation is installed in the heating flow. An additional thermal
energy meter can be installed in the domestic hot water flow to
ensure optimum domestic hot water preparation.
7.3.2 Settings on the heat pump manager
NOTE
For the evaluation of the pulses by the heat pump manager software ver-
sion H6x (or higher) is required.
During the pre-configuration of the heat pump manager, "Ther-
mal energy meter" has to be set to "Yes" to activate thermal en-
ergy metering. Depending on the system settings, the history
menu shows the values for heating, domestic hot water and/or
swimming pool. The emitted thermal energy is displayed in kWh.
The counter can be reset in the "Operating data" menu!
7.4 Solar controller for heat pump manager WPM Econ SOL
Wall-mounted solar controllers with temperature sensors for re-
cording the collector and cylinder temperature without graphic
display. The extension module is connected to the existing heat
pump manager and provides the additional inputs and outputs
required for solar control. Can be used for a heat pump heating
system with a collector array and solar energy supply in a buffer
tank. The cylinder temperature and the collector circuit tempera-
ture are shown in the heat pump manager display.
Equipment WPM Econ Sol
 Adjustable collector cooling function
 Pump kick function
 Cylinder maximum temperature
 Incl. NTC 10 (collector) and PT 1000 (cylinder) temperature
sensors
 Graphic display on the heat pump manager
7.5 General menu structure
The heat pump manager provides numerous setting and control
parameters (see Table 7.3 on page 81)
Pre-configuration
The preconfiguration tells the heat pump manager which compo-
nents are connected to the heat pump heating system. Precon-
figuration must be carried out before the actual configuration in
order to be able to show or hide system-specific menu items (dy-
namic menus).
Configuration
The menus for “Outputs”, “Inputs”, “Special functions” and “Mo-
dem”, as well as the extended setting menu, can be selected in
the menu level for experts.
