Technical details
Parameter 24 (2BN) – Pump after-run time (heating operation –
During the time which can be set using this parameter the pump continues to run after a phase of heating
demand.
Parameter 25 (2BO) – Maximum fan speed in heating operation mode –
This parameter is used to set the maximum permitted fan speed in % in heating operation mode.
Parameter 60 (2GE) – Waiting time after opening main gas valve or activation of combustion chamber
ventilator –
After a burner demand is received, the boiler start is delayed by the amount of time set using this parameter.
While this time elapses the display shows the digit ‘0’. The interval is required for the main gas valve to open
or for pre-ventilation via the combustion chamber ventilator.
Parameter 61 (2GF) - External main gas valve (possibly an LPG valve) / combustion chamber ventilator
present –
This parameter is used to indicate whether an external main gas valve or a combustion chamber ventilator
is installed.
Parameter 62 (2GG) – DHW charging (switch / pump) –
This parameter is used to indicate whether a separate pump is present for DHW charging or there is sim
ply
a switch for accessing the main pump in use.
The setting "0" means a KKP (pump outlet) and additionally a deflector (deflector outlet) is used. The setting
"1" means, that the pump at the pump outlet (X8-5/6) is only working in HZ-mode and the
DHW
-pump at the
outlet X8-7/8 is getting active in the
DHW
-mode.
Parameter 63 (2GH) – Pump – minimum PWM value –
This parameter is used to determine the minimum permitted capacity of the PWM pump in %. The minimum
PWM value is effective when the boiler output is at a minimum.
Parameter 64 (2GI) – Pump – maximum PWM value –
This parameter is used to determine the maximum permitted capacity of the PWM pump in %. The maxi-
mum PWM value is effective when the boiler output is at a maximum. The pump rpm-speed increases lin-
early between minimum and maximum boiler output.
Parameter 65 (2GJ) – Three-way valve inversion –
This parameter can be used to invert the outlet for the three-way valve wiring.
