Efficiency calculation
#
Code
Description
[9.O.4]
[F-07]
▪
0
Yes
:
The auxiliary boiler is large enough to
cover the heat demand of the building and can
therefore be considered as additional primary
heat source. Therefore, the choice between
operation of auxiliary boiler and heat pump
should be done by efficiency calculation.
▪
1
No
:
The auxiliary boiler is too small to cover
the building demand and is used solely as
backup heat source. Therefore, the heat pump
is the only available primary heat source.
NOTICE
If you enable the efficiency calculation, make sure that the installed auxiliary boiler
capacity is large enough to cover the building’s space heating demand. Enabling the
function for a too small boiler may lead to undesirable and potentially damaging on/
off switching behavior of the heat pump!
Continuous heating
The continuous heating function allows to provide space heating also during unit
defrost and can thereby increase space heating comfort. The space heating
temperatures provided during defrost depend on actual storage tank
temperatures.

No
:
Space heating is interrupted while the
heat pump is in defrost operation.

:
Space heating is provided from energy
stored in the tank while the heat pump is in
defrost operation.
