3.5 Heat pump for heating purposes only

The control PCB of the electronics module requires its own volt-
age supply 230 V AC / 50 Hz (X1/L/N/PE). The voltage supply
can be provided either directly via the mains power supply or via
the terminal strip (mains L/N/PE, 230 V AC) of the heat pump
manager. A signal line which transmits the pulse to the heat
pump manager must be connected between terminal X2-1/-2 of
the electronics module and the heat pump manager (N1).
Terminal assignment for WPM 2006/2007:
Thermal energy meter
WMZ 25 / WMZ 32
N20/X2-1
N20/X2-2
Heat pump manager
WPM 2006/2007
24VAC (G)
N1/J7-ID12
ATTENTION!
The VFS sensor for volume flow measurement must be installed the right
way round. This is the case when the cable outlet of the sensor is on the
outflow side of the measuring tube.
Terminal assignment for WPM EconPlus:
Thermal energy meter
WMZ 25 / WMZ 32
N20/X2-1
N20/X2-2
ATTENTION!
If terminal N1/J7-IDC9 is not used, this terminal must be connected with
the potential N1/G0.
