TECHNICAL INFORMATION
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 simply a
switch for accessing the main pump in use.
The setting «0» means a KKP (pump outlet) and addition-
ally 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 WW-pump at the outlet X8-
7/8 is getting active in the WW-mode.
Parameter 63 (2GH) – Pump – minimum PWM value –
This parameter is used to determine the minimum permit-
ted 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 per-
mitted capacity of the PWM pump in %. The maximum
PWM value is effective when the boiler output is at a max-
imum. The pump rpm-speed increases linearly 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.
