ture Setpoint
CoilTpSt Analog
Output
This is the
current
calculated Coil
Suction
Temperature
target during
Dehumidifi ca-
tion Mode.
NOTE:
When using Celsius scaling, all temperature values will
need to be divided by 10 by the BMS to properly read the
status and setpoint values, e.g., a value of 200º C needs
to be divided by 10 for an actual value of 20º C.
