• P13
DH
W parameter - ZKP operation
The parameter is used to set the operation time for the circulating pump cycling, so that the pump
does not run continuously and unnecessarily cools the DHW tank. The cycle time should be long
enough for the pump to supply the hot water to the last device (water tap).
Factory default setting: 15 min
• P14
DHW
parameter - ZKP pause
The parameter is used to set the pause time for the circulating pump cycling, so that the pump does
not run continuously and unnecessarily cools DHW tank. The pause time of the circulating pump
should only be long enough to prevent the domestic water from cooling too much in the pipe.
Factory default setting: 15 min
• P15
DHW
parameter - SF and SFR difference
The parameter is intended to set the minimum difference between the current temperature in the
DHW tank and the temperature of the outlet (return) water flowing from the DHW exchanger.
The function makes it possible to switch off the SLP filling pump in case of a small difference
between the two temperatures, so that there is no unnecessary circulation of water between the
heat source (boiler, accumulation tank) and DHW tank (low efficiency).
This function is active only if terminals are defined (assigned) for the SFR sensor.
Factory default setting: Off
INFO - The function is deactivated in case of active enforced losses of the accumulation
tank.
• P16
DHW
parameter - SLP shutdown difference
The parameter is intended to set the shutdown difference of the SLP filling pump, if the source
temperature (boiler, accumulation tank, EK) drops below the current temperature of the DHW
tank by the defined value.
Factory default setting: 2 K
