Coding in the delivered condition
Extended economy function mixer
A7:0 Without mixer economy function
Only for a weather-compensated
control unit and heating circuit with
mixer.
Pump idle time, transition reduced mode
A9:7 With pump idle time: heating circuit
pump "OFF" if the set value is al-
tered through a change in operat-
ing mode or through a change in
the set room temperature (only for
weather-compensated control
units)
Weather-compensated/room temperature hook-up
b0:0 With remote control: heating mode/
reduced mode: weather-compen-
sated (only for weather-compensa-
ted control units). Change code
only for the heating circuit with
mixer.
Economy function room temperature
b5:0 With remote control: no room tem-
perature-dependent heating circuit
pump logic function (only for
weather-compensated control
units). Change code only for the
heating circuit with mixer.
