INFORMATION
The auto emergency setting can be set in the menu structure of the user interface
only.
INFORMATION
If a heat pump failure occurs and [A.6.C] is set to
Manual
, the room frost protection
function, the underfloor heating screed dryout function, and the water pipe
antifreeze function will remain active even if the user does NOT confirm emergency
operation.
Equilibrium temperature
Based on the ambient temperature, energy prices and the required leaving water
temperature, the user interface is able to calculate which heat source can deliver
the required heating capacity most efficiently. However, to maximise the energy
output of the heat pump, it is possible to prevent the gas boiler from operating
when the ambient temperature exceeds a certain point (e.g. 5°C). This can be
useful to avoid too much gas boiler operation in case of incorrect settings. When
an equilibrium temperature is set, domestic hot water operation is NEVER
prohibited.
#
Code
Description
N/A
[5‑00]
Defines if gas boiler operation is allowed when
the ambient temperature exceeds the set
equilibrium temperature during space heating
operation.
▪
0: allowed (default).
▪
1: NOT allowed.
N/A
[5‑01]
Equilibrium temp.
When the ambient temperature is higher than
this temperature, the gas boiler is NOT allowed
to work. Only applicable if [5‑00] is set to 1.
Range –15°C~35°C (default: 5°C)
INFORMATION
In case that the actual outdoor temperature is lower than [5‑01] and there is a DX
operating request, the heat pump will be prohibited to give priority to DX units. In
this case, heating can only be provided by the gas boiler. If there is only a request of
the hybrid indoor unit (no DX request), then the heat pump and gas boiler will both
be able to work below this equilibrium if they are required.
