4 -OPERATION
Example:
Heating Climatic Curves (K7 to K8)
■ If OAT is invalid (not transmitted by the Inverter, out-of-range
value, etc.), the Water Setpoint is equal to the current Max.
Water Temp.
■ If OAT is above the current Maximum OAT threshold, the Water
Setpoint is equal to the current Min. Water Temp.
2/ Fixed water setpoint
If the cooling climatic curve [P586] or the heating climatic curve [P581]is configured to "-1", the water control point will be determined
according to the Occupancy mode.
The water setpoint can be configured in two ways:
■ By direct access to the WUI (refer to WUI end-user manual)
■ By accessing the parameter menu via WUI or JBus or Proprietary Protocol (refer to § 7. Parameter Overview)

The climatic curve corresponds corresponds to the water setpoint
in Home mode. To define the other occupancy modes, it is
necessary to configure Heating Sleep Offset [P402] and Heating
Away Offset [P403]:
