SINGLE UNIT ALARM SCREEN
SINGLE UNIT CONFIGURATION SCREEN
MEMBER SCREEN TERMINOLOGY
HOME SCREEN
"LP" – Low Pressure: indicates the suction line pressure on the
low side of the system
"HP" – High Pressure: indicates the discharge line pressure on
the high side of the system
"LLSV" – Liquid Line Solenoid Valve: indicates the position of
the LLSV (open or closed)
"Comp" – Compressor: indicates the status of the compressor
(on or off )
"TempSet" – Tank Temperature Setpoint: indicates the
desired tank temperature to be maintained
"CondFlow" – Condenser Flow: indicates if there is water
flowing through the condenser
"Cond" – Condenser Temperature: indicates the leaving water
temperature from the condenser
"SLT" – Suction Line Temperature: indicates the suction line
temperature of the unit right before the compressor
"Evap1" – Evaporator 1: indicates the evaporator temperature
of the first evaporator
"CTD"– Compressor Time Delay: indicates remaining time in
compressor delay countdown
"PTD" – Pump Time Delay: indicates remaining time in pump
countdown, when the count down starts the pump turns on
"Remote Mode Indicator" – indicates if this unit is connected
to a master panel via Ethernet, if it isn't then it will display a
start button if a tank temperature probe is installed
"Alarm Indicator"– indicates if there is a system alarm, click
on the button to see which alarm is currently triggered
"Defrost Indicator" – indicates if the unit is in a defrost cycle
(in a defrost cycle the compressor shuts off and lets the fans
run to warm up the evaporator)
"Evap Flow" – indicates if the evaporator has flow.
"Tank" - Temperature read out of the tank the unit is heating
"SH" - Compressor Superheat
"ENV" - Indicates whether unit is in normal performance en-
velope, extended envelope, or out of envelope
ALARM SCREEN
"HIGH PRESSURE" – indicates if the unit has alarmed out on
high pressure
"LOW PRESSURE" – indicates if the unit has alarmed out on
low pressure "SHORT CYCLE" – indicates if the unit has been
short cycling
"OUTLET FLOW" – indicates if the unit has alarmed out on
condenser water flow
"Evap Flow" – indicates if the evaporator has flow.
"M PROTECTION" – indicates if the unit has alarmed out on
motor protection
"Out of ENV" - Unit shutdown after being outside perfor-
mance envelope for 2 minutes without being able to stage the
VFD up or down at max or min speed.
CONFIGURATION SCREEN
"Temperature Diff" – Temperature Differential: sets the
temperature difference below setpoint where the unit will
turn on (only available if the unit isn't in remote mode)
"CondFlow" – Condenser Flow: indicates the flow-rate
through the condenser (based on frequency read by PLC
through integrated paddle wheel flow sensor)
"Low Limit" – Sets the lowest flow rate limit that the unit will
shut off at (enabled for Single-Pass applications only), press the
save button to save the lower limit in a Single-Pass configuration
"Compressor Hours" – Compressor Hours: indicates the run
hours of the compressor
"Purge" button – this button will run the pump relay for 2
minutes to allow you to purge the system without turning on
the units
"Tank/Pipe" - Unit call probe location, probe is recommended
inside of tank whenever possible.
"Diff Timer" - Timer to control tank load matching with a VFD
operated compressor.
