Solar Mode; Representative Scheme Of Solar Thermal System With Hp - Bosch HP270-2 Technical Manual

 The HP will just reach the normal set point
 The HP will turn ON if:
 PV signal active more than 10 min, T top < T set-3ºC

5.2) Solar mode

HP detects if the thermal solar system is working, and stop the operation of the heat pump in order to maximize the
gain from thermal solar energy.
The appliance through the kit is able to detect the solar thermal gain, so in case the solar source thermal power is
considered to be insufficient, the HP should remain working in parallel (HP + Solar).
Refer to the IM of accessory (6720808239) for instruction of parameters selection and definition (acess Coil)
Within the "Coil" parameter, only one type of external system can be selected:

solar system can be used with HP, but without any control of priorities or management from the HP

solar system has priority over HP operation in order to maximize solar thermal gain, so the HP will
manage the start and stop according the power input from solar system.
