Condenser Pressure
Displays the refrigerant pressure in the condenser.
Leaving Heating Condenser Liquid Tempera-
ture
Displays the temperature of the liquid as it leaves the
heating condenser tube bundle. Only appears when the
Heat Recovery is enabled.
Entering Heating Condenser Liquid Tempera-
ture
Displays the temperature of the liquid as it enters the
heating condenser tube bundle. Only appears when the
Heat Recovery is enabled.
Heating Condenser Liquid Flow Switch (LED)

condenser tube bundle. Illuminates when liquid flow
is present. Otherwise, it is extinguished. Only appears
when the Heat Recovery is enabled.
Drop Leg Refrigerant Temp
Displays the temperature of the refrigerant in the drop
leg between the condenser and evaporator shells, if the
sensor is present.
Subcooling Temperature
Displays the difference between the Condenser Re-
frigerant temperature and the Drop Leg Refrigerant
temperature. The Condenser Refrigerant temperature
will be represented by the Condenser Saturation tem-
perature. If the Drop Leg Sensor is not present, this
temperature is not displayed.
High Pressure Switch (Open / Closed)
Displays the present position of the high pressure
switch. This will indicate whether a high pressure fault
is present.
Condenser Liquid Flow Switch
Indicates whether flow is present in the condenser.
