input (X2M/35a)
▪ 2: 2 contacts. Connected to 2 digital inputs
(X2M/34a and X2M/35a)
Leaving water temperature: Delta T
For more information, see "10.6.3Main zone"[4168].
# Code Description
[3.B.1] [1-0C] Delta T heating: A minimum temperature
difference is required for the good operation of
heat emitters in heating mode.
▪ If [2-0D] = 2, this is fixed to 10°C
▪ Else: 3°C~10°C
[3.B.2] [1-0E] Delta T cooling: A minimum temperature
difference is required for the good operation of
heat emitters in cooling mode.
▪ 3°C~10°C
WD curve type
There are 2 methods to define the weather-dependent curves:
▪ 2-points (see "10.5.22-points curve"[4159])
▪ Slope-Offset (see "10.5.3Slope-offset curve"[4160])
In [2.E] WD curve type, you can choose which method you want to use.
In [3.C] WD curve type, the chosen method is shown read-only (same value as in
[2.E]).
# Code Description
