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:
Explanation
Room thermostat
Closed contact is a prerequisite for enabling the burner in heating mode.
No function for DHW mode.
1
No function for emissions test mode and frost protection, no error message.
Open contact blocks the enabling of the heating and the heating circuit pump
(pump run-on).
Maximum thermostat/system pressure switch
Closed contact is a prerequisite for enabling the burner in heating and DHW
mode.
2 When the contact is opened, the burner switches off and the pump run-on
begins - no 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 damper
Function monitoring of the flue gas/ventilation air damper with zero volt 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 pushbutton
6 After the DHW circulation pushbutton is activated, output A1 is switched on for
5 minutes, if output A1 is programmed as DHW circulation pump (A1 = 13).
Header sensor
7
A header sensor (5 K-NTC) is connected at E1; observe parameter HG 06.
Burner blocking
Operation without burner.
Closed contact, burner blocked.
8
Heating circuit pump and cylinder primary pump run in standard mode.
In emissions test mode and frost protection, the burner is enabled.
Open contact enables the burner again.
External burner demand
Closed contact, TKset is set to TKmax -5 K.
10
Demand also functions in standby; cycle block active
(control of output A1 when parameter output A1 = 14).
0, 3, 4, 9, 11 are without function.
