11.3.1 Setting the hybrid mode
The P100 parameter can be used to influence how the boiler and
heat pump interact. This is also called bivalent mode. The following
settings are possible: P100:
0 = Entirely electric (boiler not activated).
In this mode, the boiler is not activated, not even when defrosting.
1 = Standard COP setting
If the heat pump is set below a specific COP, this mode switches
over to the boiler. The lower the COP set, the longer the heat
pump will run. The COP threshold value can be set using P101.
The standard value is 2.0. Operation is not aected by the rate
settings (as in point 3).
2 = Ecological (based on CO emission)
Using P143, the CO emission for kWh of electricity is set (grams
of CO per kWh). This value is weighted against the CO emission
from natural gas. This emission value can be found in your energy
bill or from your energy supplier.
3 = Economical (based on rates)
In this mode, the COP threshold is determined based on the gas
and electricity rates. A low and high rate can be provided for
electricity:
► P140: High electricity rate (£ sterling per kWh)
► P142: Low electricity rate (£ sterling per kWh)
► P144: Natural gas rate (£ sterling per m)
The hybrid system consists of heat pump (ODU = outdoor unit),
the boiler (B) and the indoor unit (IDU). The 3 units work together to
optimise eiciency based upon the catagories that are input and
the average COP (coeicient of performance), using the lowest
possible cost price and/or CO emission.
There are three categories for space heating:
1. Heat pump only
2. Heat pump + boiler assistance
3. Boiler only
Using P102, the external temperature can be set to a value above
which the boiler is prevented from being activated. By lowering
this value, the system is forced to operate the heat pump for longer
without involving the boiler.
Using P103, the system can be forced to switch over to the boiler,
even if the heat pump COP is still above the COP threshold value.
1. Typically, the heat pump is used for as long as possible.
2. If the heat pump cannot achieve the desired heat level (within
the set time frame), the boiler will assist the heat recovery
process.
3. Switching to the boiler will only occur if:
• There is a heat pump malfunction.
• The heat pump is unable to achieve the requested target
temperature.
• The average COP is lower than the current COP threshold
value P101.
• The external temperature is below the value set for P103.
• The current return temperature is higher than the value set
for P104.
