Start-up - initial settings and functions
2.6 dTSC (standard: 2 - settable: 1/10)
Defines the range between the room air temperature (Ta) and the setpoint (TS) within which the unit starts to
operate in Cooling mode. The heat pump starts when Ta ≥ TS + dTSC and stops when Ta ≤ TS.

NOTE
The parameter is only used if the unit's Cooling mode control is on room air temperature.
2.7 t_INTERVAL_COOL (standard: 5 - not adjustable)
Defines the minimum minutes between compressor shutdown and subsequent restart in Cooling mode.
Among the climate curves that can be set for Cooling mode, a customisable one can be set with logic as
shown in the graph.
2.8 T1SetC1 (standard: 10 - settable: 5/25)
Sets the maximum water supply setpoint for the customisable climate curve in Cooling mode.
2.9 T1SetC2 (standard: 16 - settable: 5/25)
Sets the minimum water supply setpoint for the customisable climate curve in Cooling mode.
2.10 T4C1 (standard: 35 - settable: -5/46)
Sets the minimum outdoor air temperature at which the setpoint T1SetC1 is activated for the customisable
climate curve in Cooling mode.
2.11 T4C2 (standard: 25 - settable: -5/46)
Sets the maximum outdoor air temperature at which the setpoint T1SetC2 is activated for the customisable
climate curve in Cooling mode.
2.12 ZONE1 C-EMISSION (standard: CRP (2.1-8.1) / CVC (9.1-14.1) - settable: CRP/CVC/RAD)
Sets the type of distribution system in Cooling mode of the system’s zone 1.
L
NOTE
CRP = radiant / CVC = fan coils / RAD = radiators.
2.13 ZONE2 C-EMISSION (standard: CRP (2.1-8.1) / CVC (9.1-14.1) - settable: CRP/CVC/RAD)
Sets the type of distribution system in Cooling mode of the system’s zone 2.
L
NOTE
CRP = radiant / CVC = fan coils / RAD = radiators.
