Mixing valve:
To control the second water temperature
(only for circuit 2).
Values are adjusted for the use with the
2nd zone mixing kit accessory
ATW-2KT-05. It is highly recommended not
to change these values.
In case of using a mixing kit different from
the ATW-2KT-05 configure the following
parameters:
• Proportional band:
0 ~ 20 K (6.0 K by default).
• Integral reset factor:
0.0 ~ 20 % (2.5 % by default).
• Running time factor:
10 ~ 250 sec (140 sec by default).
• Over temperature offset protection:
OFF, 3 ~ 10°C (5°C by default).
The "Deactivated" option sets
the circuit as disabled.
