9.2 Appliance function
Heating circuit
The heating circuits operate fully automatically
with weather compensation and summer/winter
changeover.
DHW
DHW heating is according to the default target
value. The efficiency of the system can be
increased with a DHW time program.
Anti-legionella function
To prevent legionella, the DHW has to be
periodically heated to a temperature of at least
60°C. The anti-legionella function is automatic and
can be controlled via a time program. Depending
on the system version, the electric booster heater
is activated.
Second heat generator
OCHNSER AIR EAGLE heat pumps are supplied
with an electric emergency/booster heater as
standard. The electric immersion heater is built
into the MFA module and is required to ensure the
operational reliability of your heating system.
Protect the supply voltage in the main distribution
box across all poles. The voltage is supplied via the
KM3 contactor and is automatically switched on
by the system.
Effect of the electric emergency/booster heater
in the heat pump flow:
•
Mono energetic operation
The electric emergency/booster heater
guarantees heating mode and the provision of
high DHW temperatures when the bivalent
point is not reached.
•
Emergency mode
Should the heat pump fail due to a fault, the
heating output is provided by the electric
emergency/booster heater.
For the operational reliability of your heating
system, ensure the power supply to the electric
booster heater at all times!
Screed drying program
In case of return temperatures <25°C (room
temperatures) the heat for drying has to be
provided by the electric emergency/booster
heater! At these low system temperatures the
heat for drying must not be provided by the heat
pump as the frost protection of the appliance can
no longer be guaranteed during the defrost cycle.
At the end of the drying out program, the electric
emergency/booster heater can be disconnected
as long as it is not required for the operation of the
appliance. Note that emergency operation is not
possible in the screed drying program.
9.3 System operation
Running costs
Depending on the residual building moisture,
increased running costs of up to 50% are to be
expected.
Flow temperatures
To ensure energy saving operation of the heat
pump, try to keep the heating flow temperature
(and also DHW temperatures) as low as possible.
For EAGLE heat pumps, the max. system
temperature should be limited to 60°C.
NOTE
Increasing the room temperature by
1°C results in an increase in
consumption of 5-7%.
