Accumulation tank submenu- overview of defined elements:
PF sensor - upper accumulation tank sensor
(NTC sensor 20 kΩ) - temperature necessary
to control the operation of the entire heating system. It has a fundamental effect on the
switching on of the boiler circuit pump, the DHW pump and the heating circuits (see
Accumulation tank menu).
FPF sensor - lower accumulation tank sensor (NTC sensor 20 kΩ) - sensor is activated and
used for boilers with pellet burner (with BRE function). Boiler control function (burner
- on/off) according to two sensors, PF (upper) and FPF (lower) on the accumulation tank.
The temperature is not set up, it is automatically calculated according to the requirements
of the heating system. Only the minimum required temperature can be set, which is defined
by P18
