Keep the shut-off device in the heating/cooling water circuit
closed.
Restore the power supply to the heat pump using the mobile
cut-off device.

NOTE
Open motor protection switch -Q1 and -Q3 to prevent a

The internal control and supply voltage has now been com-

supply points and the cut-off mechanism – see the circuit

4.2.4 Flow rate switch (each time
This process description is based on the use of a pGD0 display
or a pGDx display in emulator mode.
If the heat pump to be tested has been integrated without an
external four-way reversing valve, then it is essential for the de-
vice to have a co-current flow when heating and a counter-cur-
rent flow when cooling. In this case, it is sufficient to check the
flow rate switch for cooling.
Testing the flow rate switch for heating with
counter-current:
 Block the heat pump using e.g. "special functions" -> "system
control M11" (ON)
 Check whether M16 is switched off under the menu item "out-
puts"

 Loosen the knurled nut on the flow rate switch for cooling until
it can be turned but does not leak
 Turn the flow rate switch until the plug can be removed using
a screwdriver

On the flow rate switch for cooling with counter-current, re-
move the plug (see Fig. 4.1 on page 15 and Fig. 4.2 on
page 16)
The flow rate switch for heating with counter-current re-
