b2:8
With remote control and for the
heating circuit, operation with room
temperature hook-up must be pro-
grammed: Room influence factor 8
(only for weather-compensated
control units; only change the code
for the heating circuit with mixer)
b2:0
Without room influence
b2:1
to
b2:64
Room influence factor adjustable
from 1 to 64. The higher the value,
the greater the room influence.
b5:0
With remote control: No room tem-
perature-dependent heating circuit
pump logic function (only for
weather-compensated control
units; only change the code for the
heating circuit with mixer)
b5:1
to
b5:8

tion, see the following table:
