The fan will cool down the heat exchanger according to the temperature settings (parameters) of the software. With this cooling parameter the
maximum run time of the fan can be programmed.
P2LK Max cooling time (display D4) [min.]
The fan will cool the heat exchanger according to parameter P2 LJ, but the fan will never run for cooling longer than the period programmed
with this parameter P2 LK. “0” = cooling function off.
For S1 > local set point P6BA – P2LJ
 fan starts after 1 minute and stops after 3 minutes
During post pump circulation, no post ventilation takes place.

Settings for gas types: natural gas, propane or butane-propane mixture (B/P).
P4 BD Gas type (0=standard, 1=propane, 2=butane/propane (B/P)) (display D8).
This parameter is set 0 for the natural gas G20 or G25.
By setting this parameter 1 for propane, fan speed is reduced.
Set this parameter 2 for B/P.
0 = standard gas (e.g: natural gas)
1 = propane
2 = B/P
For each setting, the relevant Soft start settings are automatically adjusted, depending on its main setting P4BE.
In case of gas conversion, paste the corresponding
sticker at the appropriate position in the water heater
and mark the square for the used gas type. Also mark
the square, indicating that the correct value has been
set for parameter P4BD.
(In the example on the right, ‘propane’ and ‘P4BD = 1’
have been marked).
