Working Limits:
Limit for the temperature set-point to
prevent high or low temperatures at
Space Heating or Space Cooling:
•
Maximum supply temperature
• Minimum supply temperature
Water calculation mode:

or Space Cooling).
• Deactivated
•
Points
•
Gradient (only in heating mode)
•
Fix
See detailed explanation below.
Eco Offset Water setting:
Configure the offset water temperature
for the ECO mode for Space Heating
or Space Cooling.
By using this function, current water
temperature setting is reduced by the
indicated parameter.
•
Range: 0 ~ 10
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 ºC
(5 ºC by default).
