This is defined by two reference points (flow temperature set- points at 25°C and 35°C).
  • Page 84 • Summer compensation Line Function Summer compensation start at OT Summer compensation end at OT Summer compensation setpoint increase In summer the “cooling comfort setpoint” (line 902) is gradually increased according to the outdoor temperature. This saves on cooling power and prevents the differences between the ambient tem- perature of the room and the outdoor temperature being too high.
  • Page 85 • Flow setpoint limitation Line Function Flow temperature setpoint minimum at OT 25°C Flow temperature setpoint minimum at OT 35°C It is possible to assign a lower limitation to the cooling flow temperature. The limitation line will be defined by two reference points. In addition, the resulting flow setpoint will have a lower limitation and may not be less than 5°C.

  • Page 87 • Room temperature limitation setback Line Function Room temperature limitation The room temperature limitation function enables shutting off the cooling circuit pump if the room temperature falls below the adjusted room temperature setpoint (with summer compensation: line 920) by more than the adjusted differential. The cooling circuit pump is reinitialized as soon as the room temperature rises again above the current room temperature setpoint.
