141 Override input selection
Circuit Setting range
I / II OFF / 1 ... 6
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: Closed switch:
Comfort temperature Setback temperature
Changeover switch:
Setback or comfort temperature
Connection example with ECA 9010
(used if the override switch does not have gold-plated
contacts).
Green (S1 ... S6)
16 - Brown
15 - Red
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).

147 Activation of solar panel circuit
Circuit Setting range
II OFF / 0.1 ... 99.9 K
Determine whether the solar panel circuit should be active.
OFF: A solar panel circuit does not exist, or is
deactivated.
This setting is to be chosen for system types
10.1 to 10.8 that make use of the module
ECA 80.
0.1 ... 99.9:
Pump P2 is cut in when the temperature
difference between the solar panel
temperature sensor S8 and DHW tank
temperature sensor S7 is higher than the set
value.
148 Deactivation of solar panel circuit
Circuit Setting range
II OFF / 0.1 ... 99.9 K
Determine when the solar panel circuit should be deactivated.
0.1 ... 99.9:
Pump P2 is cut out when the temperature
difference between solar panel temperature
sensor S8 and the DHW tank temperature
sensor S7 becomes is lower than the set
value.
149 Delay of alarm A2
Circuit Setting range
II 0 ... 99 sec.
Determine the delay time of alarm A2.
0 ... 99:
The alarm memory registers an alarm A2
(motor protection failure) when it is present
for a longer time that the set value.
Consequently, alarms that are only active for
a shorter time are ignored.
