9 Commissioning
Commissioning must be carried out by Ochsner Cus-
tomer Service or a service partner authorised by
Ochsner. The Ochsner commissioning guidelines must
be adhered to. Operating the system without a correct
commissioning will lead to a forfeiture of the guarantee
and warranty rights.
9.1 Required on-site personnel
Electrician, installer and future system supervisor
MUST be present for the system orientation during
commissioning.
INSTRUCTIONS for the system installer.
•
The OCHSNER Customer Service engineer /
Customer Service partner will execute the user-
specific settings
according to the specifications
in the system data sheet.
•
Should the system installer not be present during
commissioning, or if there is no fully completed
system data sheet present, the system will be
commissioned using the control's factory settings.
•
OCHSNER accepts no liability for possible mal-
functioning (heating curve too low, bivalent point
too high, etc.). Any claims resulting from this will
be invoiced to the system installer.
•
In order to run the system economically,
it is absolutely necessary that the system be bal-
anced hydraulically and that the control settings
are coordinated to the system requirements.
•
Other necessary work performed, such as bleed-
ing the system, electrical wiring, additional instruc-
tion etc., that do not fall within the realm of the
OCHSNER firm’s duties will be invoiced separate-
ly
9.2 Non-self-resetting safety thermostat
At outside temperatures below - 15 °C, the non-self-
resetting safety thermostat can trigger the electric
emergency/auxiliary heater. Check whether the safety
thermostat has been activated.

button.

9.3 Appliance function
Electric emergency/auxiliary heater in the heat pump
flow:
•
Mono-energetic operation
The electric emergency/auxiliary heater guaran-
tees the heating operation as well as higher water
temperatures if the outside temperature falls be-
low the bivalent point.
•
Emergency operation
If the heat pump malfunctions, the heating will be
taken over by the electric emergency/auxiliary
heater.
•
Heat-up program
(underfloor heating only)
For return temperatures <25 °C, the electric emergen-
cy/auxiliary heater must take over the drying out of the
flooring screed!
The drying out cannot be carried out using the heat
pump as the system temperatures are too low and,
during the de-icing cycle the frost protection cannot be
guaranteed.
At the end of the drying out program, the electric
emergency/auxiliary heater can be disconnected if it is
not needed for the normal appliance operation.
Please note that the emergency operation cannot be
activated during the drying out program.
Anti-legionella switching
The electric emergency/auxiliary heater will be auto-
matically switched on if the anti-legionella program is in
place. The water will be regularly heated to 60 °C as
protection against Legionella.
