SYSTEM CONFIGURATION
Heat pump connection to the system without low-loss header.
Make sure the useful pressure head of the circulating pump on the unit is sufficient for the pressure drop in the sys-
tem. If the minimum system content does not reach values shown in this manual, install an additional storage tank on
the heat pump return pipe.
No system configurations are required.
On systems where the heat pump is connected directly to the system, without storage tank and secondary pumps, para-
meter 011D must be set to 0.
In this way, the heat pump is controlled based on room temperature and the time bands, when enabled.
It is recommended to enable operation of the pump on the unit by setting parameter "0143=0 system pump always on"
