CONTROLLING OPTIONS AND SETTINGS
11.1
General
The following sections describe some general functions of the water heater and their possible use.
M
AX COOLING TIME
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 P2LK. “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.
TEMPERATURE DISPLAY ON
/
OFF
Selection for showing the measured temperatures in the operation display of the water heater.
P5BJ
Temperature display 1=on (display D5)
The measured temperature in the operation display.
0 = not visible
1 = visible
G
AS TYPE SELECTION
Settings for gas types: natural gas, propane or butane/propane mixture (B/P).
P4BD
Gas type (0=standard, 1=propane
, 2=butane/propane (B/P)) (display D8).
This parameter is set 0 for the common used gas types such as natural gas G20 or G25.3.
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
By each setting, the relevant Soft start settings are automatically adjusted, depending on its main setting P4BE,
see next section § 11.1.4.
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).
