where Y is the channel currently being scanned and
XXXX is the refrigerant concentration of that channel.
Saturated Evap Temperature/Compressor
Discharge Temperature (ASHRAE Report)
Compressor Starts and Running Time (ASHRAE
Report)
The starts and hours counters are displayed:
The compressor starts counter is increased with
each start or attempted start of the compressor.
Evaporator Entering and Leaving Water
Temperatures (ASHRAE Report)
Saturated Evap Temperature/Evaporator
Refrigerant Pressure (ASHRAE Report)
Evaporator Approach Temperature (ASHRAE
Report)
Note: If a negative approach temperature is
displayed, check the sensors for proper operation.
Chilled Water Flow Switch Status (ASHRAE
Report)
The screen displays the status of the chilled water
flow switch at the input to the UCM.
where [Y] is “Open/No Flow” or “Closed/Flow”
Condenser Entering and Leaving Water
Temperatures (ASHRAE Report)
Dashes will be displayed for either temperature if the
input is open or shorted.
Saturated Condenser Temperature/Condenser
Refrigerant Pressure (ASHRAE Report)
Condenser Approach Temperatures (ASHRAE
Report)
Condenser Water Flow Switch Status (ASHRAE
Report)
The screen displays the status of the condenser
water flow switch at the input to the UCM if and only if
the differential water pressure sensor option is not
installed.
where [Y] is “Open/No Flow” or “Closed/Flow”
