Heating circuit 2
:
–
No
: Heating mode corresponds to the
heating curve.
–
Yes
: Heating mode corresponds to the
heating curve but without heating in the
cooling down phase. Only at the point
when the room temperature reaches the
required room temperature for the next
lower operating mode for the first time
(e.g.
Economy
with 59.0 °F (15.0 °C))
does the heating correspond to this
operating mode.
•
Heating OFF at outdoor temperature
(Warm
weather shut down WWSD):
Use this menu option to set the outdoor
temperature for the
Heating circuit 1
and/or
Heating circuit 2
at which the heating is to

...
77 °F
(
10 °C
...
25 °C)
: Outdoor
temperature at which heating is turned off.

•
Risk of freezing at outdoor temperature
: Use
this menu option to set the frost protection
threshold temperature at which the heating
for the
Heating circuit 1
and/or
Heating
circuit 2
is to switch on:
If the outdoor temperature exceeds the set frost
protection threshold temperature by 1.8 °F
(1 °C) and there is no heat demand then the
heating pump in the heating circuit switches off.
–
If the outdoor temperature does not
exceed the frost protection threshold
temperature then the heating pump in the
heating circuit switches on (system frost
protection).

periods of outdoor temperatures
below 32 °F (0 °C), if the frost
protection threshold is set too low.
B
The frost protection threshold
(37 °F (3 °C)) should only be
adjusted by an installer.
B
Do not set the frost protection
level too low!
Damage caused by the frost
protection threshold being set
too low is not covered under
warranty.
