• P08
Accumulation tank
parameter - Tank protection during discharge
The parameter is intended to turn on the protection of the accumulation tank before complete
discharge (cooling) to a temperature lower than the PFmin temperature ( → P01
Accumulation tank
parameter).
Setting options:
On – function is on
Off – the function is off (circuits will be in operation regardless of the temperature in the
accumulation tank)
Factory default setting: Zap
• P09
Accumulation tank
parameter - Tank protection during charging
The parameter is intended to switch on the protection of the accumulation tank against accidental
cooling through the boiler (protection against filling with colder water) by the pump in the DKP
boiler circuit.
Setting options:
On – function is on - the pump in the DKP boiler circuit is in operation (enabled) only
if the temperature of the WF boiler is higher by difference ( → P16
Accumulation tank
parameter) than the PF temperature in the accumulation tank.
At the same time, the pump in the DKP boiler circuit is off (prohibited), if the
temperature of the WF boiler is lower by difference ( → P15
Accumulation tank
parameter)
than the PF temperature in the accumulation tank.
Off
– function is off
Factory default setting: On
• P10
Accumulation tank
parameter - Tank operating mode
The parameter is intended to distinguish the function of the accumulation tank with respect to its
(volume):
Large tank (min. 55 L / for installed kW of boiler) = accumulation tank
Small tank (500 - 1,000 L, e.g. 25 L / for installed kW of boiler) = buffer tank
Factory default setting: according to selected hydraulic diagram
10. Setting menu - A
