ments. Intermittent ventilation is considerably more energy
efficient than permanent ventilation, and therefore saves
money. Avoid permanent ventilation.
4.1.3 Heating setback program
From an energy efficiency point of view, using a time pro -
gram to reduce the heating flow temperature is especially
not recommended for air/water heat pumps with low tem-
perature heating systems (such as underfloor heating).
These systems are slow to respond and, due to the addi-
tional output from the system required following the end
of the setback phase, it is possible that the second heat
generator (boiler, electric immersion heater) will cut in. This
can lead to higher operating costs.
5. Maintenance and care
We recommend an annual inspection and if necessary
have your heat pump serviced by OCHSNER Customer
Service.
Material damage
Maintenance work on electrical components of the
heat pump may be carried out only by qualified
contractors.
Material damage
Abrasive tools must not be used to clean the evap-
orator fins in the outdoor unit.
»
Any dirt on the fins should be blown away
using compressed air (max. 8 bar), in the di-
rection of normal air flow.
»
If the fins are very dirty, contact your OCHS -
NER system partner or OCHSNER Customer
Service.
»
If it is necessary to clean the casing sections of the
indoor or outdoor unit, use only a damp cloth (with
water or a weak soapy solution). Do not use any abra-
sive or aggressive cleaning materials.
»
During the building phase, protect the indoor and
outdoor units from dirt and dust with a suitable cover.
Use the plastic cover provided.
»
Ensure that the heating circuit is filled with sufficient
water.
»
Ensure that any condensation beneath the outdoor
unit can drain away without freezing all year round.
»
Ensure that the outdoor unit (both the top and the un-
derside) is kept free from snow, leaves and twigs and
other foreign bodies.
i Information
If the outdoor unit is covered with a thick layer of
snow, this can reduce system efficiency.
»
Remove snow on and around the outdoor unit
as necessary.
»
If required, install the snow cover available as
an accessory for the outdoor unit.
i Information
Ensure that the refrigerant circuit of your heat pump
is tested for leaks once a year (in acc. with Regu-
lation (EU) no. 517/2014).
»
Ensure year-round access to soldered joints in
the refrigerant circuit.
»
Document the results of the leakage test in the
system test report.
6. Problem solving
Problem Cause Solution
Too little DHW
is available
or the cen-
tral heating
system is too
cold.
The power
supply to the
appliance has
been cut off
Check the safety device on the
main distributor board for your
house. Switch the safety device
back on. If the safety device trig-
gers again after being switched
back on, contact a qualified con-
tractor or OCHSNER Customer
Service.
The appliance
is leaking
water.
The drain
for the safe-
ty valve is
blocked.
Clean the safety valve drain. See
„Safety valve drain“ on page 32.
If you have a problem that you cannot resolve, contact
the system installer, a qualified contractor or OCHSNER
Customer Service.
Faults are displayed as”Er XXX”on the master controller of
the OTE control unit. If a fault occurs, contact your system
installer. The system installer knows your hydraulic system
and how it operates. The causes of faults can often be
found in the settings or in the hydraulics.
Before contacting the installer, make a note of the serial
number and the heat pump model. The serial number and
heat pump model of your appliance are shown on the name
plate. The name plates are attached to the back of the
appliance on the outside and behind the front appliance
casing panel (control box outer side).
