- to be selected when PV system is feeding the house, in order to ensure hot water even without PV
energy as the s
olar electricity is mainly fed into the grid
- to be selected when PV system is connected directly to the HP and s
olar electricity is used for own
consumption first and only excess electricity is fed into the grid
Resume:
“Suel” OFF – HP will work as normal independently of PV energy in production
With PV
– heat pump switch ON to reach “Tset”
Without PV
– heat pump switch ON to assure “T set – 3ºC” and keep operation to reach “T set”
“Suel” ON – HP will only work if there is PV energy in production
With PV
– heat pump switch ON to reach “Tma”
Without PV
– heat pump switch ON to ensure “T min”
5.1.2)
The “Cont” parameter aims the adaptation of the signal output for detection of PV production according
the selection of the existent inverter.
Normally Open
– Inverter with contacts normally open (no PV production). In case of solar gain, contacts close
and HP starts counting 10 min for confirmation.
Normally Closed
– Inverter with contacts normally close (no PV production). In case of solar gain, contacts open
and HP starts counting 10 min for confirmation.
5.1.3)
The “Por” parameter will ensure the priority of the operation over the defined periods of HP operation.
Note: This parameter is not existing in HP270-3 and HP200/250-1 as the priority to heat up water is
always considered.
