I set a waterheater heat pump combined with a low temperature system (radiant floor) I used:

  • the curves fit tool spreadsheet to set up my heat pump
  • outdoor air only (inlet air configuration)
  • setpoint temperature schedule name (42 ° C) for the tank
  • heating thermostat (21 ° C)
  • setpoint manager schedule (35 ° C)
  • compressor location outdoors

I noticed that by shifting the compressor setpoint temperature schedule from 50 ° C to 45 ° C, electrical consumption more than doubled. could someone tell me why and which could be corrected? thank you
