6.2.11 VENTING THE HYBRID MANAGER
▶ Open manual air vent valve.
▶ Close the manual air vent valve as soon as there is sign of water
present. This prevents air being drawn into the system again.
▶ Select Hybrid manager circulating pump speed stage III.
▶ Select the “Function test” menu at the FW200 programming unit, in
order to operate the Hybrid manager circulating pump ( Operating
instructions of the FW200 programming unit).
▶ Let the Hybrid manager circulating pump run for a short time, subject
to system layout and size.
▶ Stop the Hybrid manager circulating pump via the “Function test”
menu.
▶ Open manual air vent valve.
▶ Close the manual air vent valve.
▶ Repeat steps 3 to 8 until the system has been completely vented.
▶ After venting the system, adjust the pump ( section 6.2.9).
6.2.12 SETTING THE BYPASS VALVE
Set the bypass valve subject to the selected pump curve:
• Speed stage I
bypass setting = 0.05 bar
• Speed stage II
bypass setting = 0.18 bar
• Speed stage III
bypass setting = 0.45 bar
▶ Select the determined bypass setting at the adjusting part of the
bypass valve.

6.2.13 SETTING PARAMETERS FOR OPTIMISING ENERGY USE AND
COSTS OF THE HYBRID SYSTEM
The hybrid system offers a choice of different operating modes:
NOTICE: Damage through pump running dry!
▶ Regularly check the water level and top up heating
system with water, if required.
We recommend the installation of a manual air vent valve
near the heating water return of the hybrid manager to
enable the hybrid manager to be vented.
Airlocks in the pump can result in noise, vent the
circulating pump to remove any air lock.
Reinstate the specified system pressure if a large
amount of air escapes from the system.
Once the bypass valve is set it is recommended to lock
the valve setting in place.
These parameters can be set either via the FW200
programming unit or via the hybrid control module.
These values are transferred and overwritten
respectively. The following explains the setting using the
FW200 programming unit. For information on setting at
the hybrid control module, see chapter 6.2.23.
Operating mode Description
Environmental factors With CO
2
-optimised mode, the system
control decides when operating the air to
water heat pump or the condensing boiler
results in the greatest CO
2
reduction.
Costs With the cost-optimised operation, the
system control decides on the basis of
current energy prices. Rising gas prices
result in longer operation of the air to water
heat pump, whilst rising electricity prices
result in longer operation of the condensing
boiler.
Environment and costs Mixed operation taking environmental
factors and costs into account.
Environmental and financial aspects are
taken into consideration.
Changeover threshold With weather-compensated operation, the
condensing boiler starts from a set outside
temperature.
