Pv Increase - Wolf BWL-1S-05 Installation And Operating Instructions Manual

30.3 PV increase
The PV increase function enables an adjustment in heat pump operation, e.g. when connected to a photovoltaic
(PV) system to optimise on-site consumption of PV energy.
An external switching command (floating contact on terminal X1 – 11/12) can increase the set temperature for
heating and/or DHW, or enable the active cooling function.
The heat pump can be operated using a compressor, electric heater, or both a compressor and electric heater.
When configuring on-site technical devices (e.g. PV inverter), take the maximum possible power consumption of
the heat pump into account (see specification).
The PV increase status message is shown on the status pages of the BM-2 programming unit and in the
"Displays"/"Heating appliance" submenu on the AM display module and BM-2 programming unit.
PV increase for heating is possible only in system configurations with header return temperature sensor SAF
(T_headerRTN) and where the outside temperature is below the set winter/summer changeover.
For active cooling with PV increase, active cooling must be enabled in the AM/BM-2 standard settings, as well as
in contractor parameters WP058 and WP033. In addition, the outside temperature must be above the set winter/
summer changeover and the enable temperature for active cooling (WP053).
PV increase is not possible whilst power-OFF is active.
If the power-OFF function is not used, insert a jumper at terminal X1 – 9/10.
If standby mode is set on the BM-2 programming unit, PV increase is unavailable.
