Description
Displays the temperature of the refrigerant in its gaseous state at discharge of the
compressor as it travels to the condenser.
This displays the percentage of Full Load Amps utilized by the system.
Displays the current limit value in use. This value could come from a 4 mA to 20 mA, 0
VDC to 10 VDC, PWM signal, SC-EQ interface BAS mode, or a locally programmed value.
Displays the temperature of the liquid as it enters the condenser.
Displays the temperature of the liquid as it leaves the condenser.
Displays the active setpoint to which the Heat Pump is controlling the Leaving
Condenser Liquid Temperature. Only displayed when Heat Pump is enabled on the
SETUP Screen and the Operation mode is set to Heating mode on the HEAT PUMP
Screen. The setpoint could come from a 4 mA to 20 mA, 0 VDC to 10 VDC, PWM, or SC-
EQ interface in BAS mode, or a locally programmed value.
Displays the pressure difference between the condenser and evaporator (condenser
minus evaporator). This is also called the Head Pressure. This is only displayed when
Head Pressure Control is enabled.
Displays the active Head Pressure Setpoint to which the head pressure is being
controlled. This is only displayed when Head Pressure Control is enabled.
Displays the refrigerant pressure in the condenser.
Displays the saturation temperature in the condenser.
Displays the temperature of the oil in the sump. (Only displayed when a Variable
Speed Oil Pump is installed.)
