Factory setting
I / II
OFF / 1 ... 6
OFF / OFF
Choose an unused temperature sensor input for overriding the
schedule for circuit I and / or circuit II.
The override can be activated for comfort or setback mode.
For override the controller's mode must be in 'scheduled
operation'!
OFF:
The controller's schedule is not overridden.
1 ... 6:
Select an unused sensor input S1 ... S6 for
the override of the circuit in question.
Connection example
If the override switch has gold-plated contacts, you can
choose one of the following solutions:
Closed switch:
Comfort temperature
Closed switch:
Setback temperature
Changeover switch:
Setback or comfort temperature
Connection example with ECA 9010
(used if the override switch does not have gold-plated
contacts).
16 - Brown
15 - Red
Green (S1 ... S6)
The ECA 9010 module is powered by the system device bus, which
means that the bus must be active. The bus is activated by setting
the controller address to 15 (line 199).

I / II
OFF / 1 ... 30 K
OFF / OFF
The alarm is activated if the actual flow temperature (S3 / S4)
drops too much below the desired flow temperature. The max.
deviation ΔT1

is set here.
This condition must last longer than the time interval Δt
ALARM
(line 149).
See also line 148.
OFF:
The alarm function and the alarm relay of
the additional module ECA 86 are not active.
