Menu: Heating parameters > Room temperature
offset
B
Set the permanent increase in the desired
room temperature for the assigned heating
circuit, e.g. to correct system-dependent
deviations.
Menu: Heating parameters > Heating OFF until
lower level reached
B
Select cooling-down phase for the assigned
heating circuit:
–
No
: Heating mode corresponds to the
heating curve.
–
Yes
: Heating operation according to
heating curve, however no heating
operation in the cooling-off phase until the
current room temperature (e.g.
Comfort
=
70.0 °F (21.0 °C)) has reached the desired
room temperature of the next-lower
operating mode (e. g.
Economy
with
59.0 °F (15.0 °C)) for the first time. After
that, heating takes place according to the
next-lower operating mode (e.g.
Economy
with 59.0 °F (15.0 °C)).
Menu: Heating parameters > Heating OFF at
outdoor temperature (Warm weather shut
down WWSD)
B
Set the temperature for the assigned heating
circuit when it is warm enough outdoors for
heating to switch off:
–
50 °F
...
77 °F
(
10 °C
...
25 °C
): Outdoor
temperature when heating is turned off.
–
210 °F
(
99 °C
): Function switched off, i. e.
the heating can switch on at any outdoor
temperature.
Menu: Heating parameters > Risk of freezing at
outdoor temperature
•
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 set frost protection threshold
temperature then the heating pump in the
heating circuit switches on (system frost
protection).
B
Set the frost protection threshold
temperature at which the heating for the
assigned heating circuit should switch off:
Menu: Heating parameters > Mixer run time
B
Set the
Mixer run time
to suit the running
time of the mixer positioner motor used.
WARNING:
Domestic hot water
pipework may freeze during longer
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.
