Each strategy needs to be configured (although a default configuration is available) and its parameters can be set
navigating to Main Menu → View/Set Unit → Power Conservation → Setpoint Reset.
At the end of the Setpoint Reset configuration, execute an Apply Changes to make the configurations
made effective.
4.10.3.1 Setpoint Reset by OAT
The active setpoint is calculated applying a correction which is a function of ambient temperature (OAT). As temperature
drops below the Start Reset OAT (SROAT), LWT setpoint is gradually increased until OAT reaches the Max Reset OAT
value (MROAT). Beyond this value, the LWT setpoint is increased by the Max Reset (MR) value.

4.10.3.2 Setpoint Reset by External 4-20 mA signal
The active setpoint is calculated applying a correction based on an external 4-20mA signal. 4 mA corresponds to 0°C
correction, while 20 mA corresponds to a correction of the active setpoint as set in Max Reset (MR).

4.10.3.3 Setpoint Reset by Return
The active setpoint is calculated applying a correction that depends on the evaporator entering (return) water temperature.
As evaporator ΔT becomes lower than the SRΔT value, an offset to the LWT setpoint is increasingly applied, up to the MR
value when the return temperature reaches the chilled water temperature.
The Return Reset may affect negatively the chiller operation when operated with variable flow.
Avoid to use this strategy in case of inverter water flow control.
