Description
Displays the pressure differential between the high side oil pressure transducer
(output of oil filter) and the low side oil pressure transducer (compressor housing).
The displayed value includes offset pressure derived from auto-zeroing during the
System Prelube. If either of the transducers used to calculate this differential is out of
range, the display field will show XX.X. This is only displayed when a Variable Speed Oil
Pump is installed.
Displays the temperature of the liquid as it enters the evaporator.
Displays the temperature of the liquid as it leaves the evaporator.
Displays the active temperature setpoint to which the chiller is controlling the
evaporator liquid. This value could come from a 4 mA to 20 mA, 0 VDC to 10 VDC, 1 to
11 second PWM signal, communicated through an SC-EQ interface in BAS mode, or a
locally programmed value when in Local mode of operation.
Displays the temperature of the liquid as it leaves the heating condenser tube bundle.
Only displayed when the Heat Recovery is enabled.
Displays the temperature of the liquid as it enters the heating condenser tube bundle.
Only displayed when the Heat Recovery is enabled.
Displays the Hot Water Setpoint to which the Leaving Heating Condenser Liquid
Temperature is being controlled. Only displayed when Heat Recovery is enabled and
Hot Water Control is enabled.
Displays the present refrigerant pressure in the evaporator.
Displays the present saturation temperature in the evaporator.
