Explanations
A6:36 Extended economy function disabled
A6:5 to Extended economy function enabled: The burner and
A6:35 heating circuit pump will stop at a variable value, ad-
justable between 5 and 35 °C plus 1 °C. The mixer
closes.
The basis for this is the adjusted outside temperature.
This is based on the actual outside temperature and a
time constant, which takes into account the cooling
down of an average building.
Explanations
A7:0
A7:1 Heating circuit pump also "OFF":
If the mixer has been trying to close for some time.
■
Heating circuit pump "ON":
If the mixer changes to control function
■
If there is a risk of frost
■
Explanations
A9:7 Heating circuit pump "OFF" if set value is modified by
changing the operating mode or changing the set
room temperature.
Only if room hook-up is not set in parameter b0.
A9:0 No economy function outside temperature
A9:1 to Adjustable from 1 to 15. The higher the value, the lon-
A9:15 ger the pump idle time.
Explanations
B0:0 With remote control: heating mode/reduced mode:
weather-compensated
Change value only for the heating circuit with mixer.
B0:1 Heating mode: weather-compensated
Reduced mode: with room temperature hook-up
B0:2 Heating mode: with room temperature hook-up
Reduced mode: weather-compensated
B0:3 Heating mode/reduced mode: with room temperature
hook-up
Explanations
B5:0 With remote control: no room temperature-dependent
economy function.
Change value only for the heating circuit with mixer.
