7.10.1.2 Switching off the heat pump
The heat pump can be switched off either manually or automatically according to appropriate shutdown
algorithms.Depending on the shut-off reason, minimal running times of the compressor are considered or
not.
 Manual cutout
The heat pump can be switched off on the overview side of the heat pump module (see
heat pump is running (=Operating mode compressor) and the "OFF
switches off and the condensator pump and the source pump run after a set time.This run after is indicated
by the operating mode "stop".Any residual heat /cold is transported to the heat customer.
If the heat pump is not running (mode=heating mode and operating mode=ready) and the "OFF
activated, no pump run after takes place.

 Automatic shutdown
An automatic shutdown can result for several reasons. Depending on the shutdown reason, the shutdown
process can be different:
Shutdown due to missing requirement:
A demand shutdown is the normal shutdown process which is present, when no demand from the customer's
side is placed on the heat generator and so the heat demand is covered. After the demand shutdown of the
compressor the pumps run after again.The mode remains on "Heating" or "Cooling" and the operating mode
is on "Ready".
Shutdown by limit exceedance:
A shutdown by a limit exceedance occurs when internal limiting values are
switches off independently of the minimum compressor runtime and an error is displayed.The cause of the
error has to be found and the error has to be confirmed manually.
