Parameter Description Use Display
Control Temperature Differential Allowed distance from set point
Used to determine cut-in/
cut-out temperatures for
ON/OFF control.
(Self-Contained and Walk-In
only)

Control Temperature Input Selection Selects input for temperature control
Determines temperature
input used for control and
alarms. Discharge Air or
Return Air.

Low Temperature Suction Pressure
Set Point
Pressure Set Point for Low Temperature Control
In Single Temperature case
applications this is the
Pressure set point.
In Dual Temperature
case applications, this
is the Pressure set point
when operating in Low
Temperature mode

Medium Temperature Suction
Pressure Set Point
Pressure Set Point for Medium Temperature
Control
In Single Temperature case
applications this is the
Pressure set point.
In Dual Temperature case
applications, this is the
Pressure set point when
operating in Medium
Temperature mode
M
Line-up Pressure Sharing
Enable/Disable sharing of sensed pressure value
with peer controllers
Shares pressure reading
between controllers in a
line-up.
1. Required if each
controller not equipped
with a local pressure
transducer.
2. Allows for continued
superheat control from
a common suction
pressure if one or more
pressure transducer
faults occur within a
line-up.

Minimum Cooling Time
Minimum compressor runtime/refrigerant flow
time
Used when On/Off
temperature control is
selected (e.g. Walk-in with
condensing unit or Self-
contained merchandiser.
o
Minimum off time
Minimum compressor off time/refrigerant no flow
time
Used when On/Off
temperature control is
selected (e.g. Walk-in with
condensing unit or Self-
contained merchandiser.
off
Number of Cases in Line-up Number of peer cases (controllers) in line-up
Determines number of peer
controllers expected within
line-up for control and
alarming purposes.

Synchronize Evaporator Settings
Enable/Disable synchronization of evaporator
control parameters in multi-evaporator display
cases.
Synchronizes settings for
multiple evaporators in a
display case.
