Description
Max Reset (MR)
5.0°C
0.0°C  10.0°C
Max Reset setpoint. It represents the maximum
temperature variation that the selection of the EWT option
can cause on the LWT.
Max Reset (MR)
5.0°C
0.0°C  10.0°C
Max Reset setpoint. It represents the maximum
temperature variation that the selection of the DT option
can cause on the LWT.
Start Reset DT (SRT)
5.0°C
0.0°C  10.0°C
It represents the “threshold temperature” of the DT to
activate the LWT setpoint reset, i.e. the LWT setpoint is
overwritten only if the DT reaches/overpasses the SRT.
Delta T
Is the actual evaporator delta temperature. Entering –
Leaving water temperature
OAT
Actual outside ambient temperature
