when the Heat Recovery is enabled.
Displays the temperature of the refrigerant in the drop leg between the condenser
and evaporator shells, if the sensor is present.
Displays the difference between the Condenser Refrigerant temperature and the
Drop Leg Refrigerant temperature. The Condenser Refrigerant temperature will be
represented by the Condenser Saturation temperature. If the Drop Leg Sensor is not
present, this temperature is not displayed.
Displays the present position of the high pressure switch. This will indicate whether a
high pressure fault is present.
Indicates whether flow is present in the condenser.
Displays the present position of the refrigerant level if this function is enabled.
Displays the setpoint to which the refrigerant level is being controlled.
