The functions of input E1 can only be scanned and adjusted with Wolf control accessories
with eBUS capability.
The following functions can be allocated to input E1:
Meaning
Room thermostatClosed contact is a prerequisite for enabling the burner in
heating mode No function for DHW modeNo function for emissions test mode and
1
frost protection, no error messageOpen contact blocks the enabling of the heating and
the heating circuit pump (pump run-on)
Maximum thermostat/system pressure switchClosed contact is a
prerequisite for enabling the burner in heating and DHW mode When the
contact is opened, the burner switches off and the pump run-on begins - no
2
error message. Applies to all pumps.
When the mains power is on and the contact is open, there is only a pump
kick, no run-on
Flue gas/ventilation air damperFunction monitoring of the flue gas/ventilation air
damper with floating contact, Closed contact is a prerequisite for enabling the fan
and burner in heating, DHW, cascade and emissions test mode.
Output A1 must be programmed for flue gas/ventilation air damper function.
5 If output A1 is controlled and does not close input E1 within two minutes, fault
code 8 is issued.
If output A1 is not controlled, input E1 must also open within two minutes.
Otherwise FC8 is generated.
With FC8, the fan is controlled with 65% of speed stage 1.
DHW circulation remote controlAfter the DHW circulation button is activated,
6 output A1 is switched on for 5 minutes, if output A1 is programmed as DHW
circulation pump (A1 = 13)
Header sensorA header sensor (5K-NTC) is connected at E1; observe
