Note
For every appliance fault, output X2.10 issues a 230 V
signal.
In the case of temporary faults, the output switches the
signal through for a specific time.
In the case of faults that result in a permanent appliance
shutdown, the output switches through permanently.
f f You can define the characteristics of the output via
parameter "COMMISSIONING / I/O CONFIGURATION /
OUTPUT X 2.10".
10.3 High limit safety cut-out for area heating
system
!
Material losses
In order to prevent excessively high flow temperatures
in the area heating system causing damage in the event
of a fault, install a high limit safety cut-out to limit the
system temperature.
11. Commissioning
Only a qualified contractor may adjust the settings in the commis-
sioning instructions for the heat pump manager, commission the
appliance and instruct the operator in its use.
Carry out commissioning in accordance with these operating and
installation instructions, and the instructions for the heat pump
manager. Our customer support can assist with commissioning,
which is a chargeable service.
If this appliance is intended for commercial use, observe the rules
of the relevant Health & Safety at Work Act during commissioning.
For further details, check with your local authorising body (e.g.
TÜV).
11.1 Checks before commissioning
f f Before commissioning check the points detailed below.
11.1.1 Heating system
- Have you filled the heating system to the correct pressure?
- Have you closed the automatic air vent valve of the multi-
function assembly (MFG) after venting?
!
Material losses
f f
Observe the maximum system temperature in un-
derfloor heating systems.
11.1.2 Heat source
!
Material losses
If screed drying is carried out with a ground source heat
pump, the heat source can be overloaded, especially a
geothermal probe. The ground around the geothermal
probe may freeze in the process. Heat transfer to the
ground will be irreparably damaged.
f f
Observe the chapter "Menu structure / PROGRAMS
menu / HEAT-UP PROGRAM" in the commissioning
instructions for the heat pump manager.
The appliance is equipped with a source protection function. If the
temperature falls below a defined brine temperature, the appli-
ance automatically reduces the power.
11.1.3 Temperature sensors
- Have you correctly positioned and connected the outside
temperature sensor and the immersion/contact sensor (in
conjunction with a buffer cylinder)?
11.1.4 High limit safety cut-out
At ambient temperatures below -15 °C, the high limit safety cut-out
of the multifunction assembly may respond.
