Extended economy function mixer
A7:0 Without mixer economy function
(only for weather-compensated
control units and heating circuits
with mixer)
Pump idle time, transition reduced mode
A9:7 With pump idle time: Heating cir-
cuit pump "OFF" if the set value is
altered through a change in oper-
ating mode or through a change in
the set room temperature (only for
weather-compensated control
units)
Weather-compensated/room temperature hook-up

mode/reduced mode: weather-
compensated (only for weather-
compensated control units; change
the code only for the heating circuit
with mixer)

Heating circuit pump also "OFF":
If the mixer has been attempting to

close for longer than 20 min.
Heating circuit pump "ON":
If the mixer changes to control
