Defrost Menu
d0
Type of Defrosting
re = Defrosting without connecting the compressor
in = Defrosting by connecting compressor
d1
Defrosting stops when defrost probe temperature is above this value
d2
Maximum time the control will be in defrost cycle. If set to zero, control will
not defrost
d3
Hour of the day for the first defrost. No defrost cycles will take place before
this time
d4
Upon powering on the control, delay time before first defrost cycle
d5
Display during defrost cycle
Off = Current temperature displayed
On = Temperature at start of defrost cycle displayed until defrost cycle
ends and the temperature is less than or equal to starting temperature or
after the time is set in d6.
d6
Maximum time before the display returns to normal reading after a defrost
cycle
d7
Time after defrost cycle before the compressor can be started
d8
Time between defrost cycles. If set to 0, defrost must be manually actuated
d9
Determines if Fan operates during defrost
d10 Amount of time after defrost before the fan can restart
d11 Minimum duration the control remains in defrost cycle
d12 Determines which temperature probe to use to control the defrost cycle
d13 Selection of Intelligent Defrost Method
off = turns off intelligent defrost
JuP = Skips defrost cycles as necessary
CiC = Adjusts time of defrost cycle as necessary
d14 Units to count the defrost cycle
rt = according to the time the controller was on
ct = according to the time the compressor was on
d15 The time of the defrost cycle will not be counted if the evaporator
temperature is above this value
d16 Sets the normal defrost time as a percentage of d2.
d17 Value that d8 will be incremented or decremented during Intelligent defrost
when d13 = CiC
Hde Hours until next defrost cycle
nde Minutes until next defrost cycle
JdF Displays the adjustments to the defrost cycle during intelligent defrost
When d13 = JuP, displays number of defrost cycles to skip
When d13 = CiC, displays increments of d8.

Alarm Menu
A0
Alarm Differential or Hysteresis
A1
High Alarm Set Point (Deviation Value)
On when temperature reaches Set + A1 and off at Set + A1 - A0
A2
Low Alarm Set Point (Deviation Value)
On when temperature reaches Set - A2 and off as Set - A2 + A0
A3
Time of Alarm Inhibit after Continuous Cool Cycle
A4
Time of Alarm Inhibit after Continuous Defrost Cycle
A6
Time of Alarm Inhibit after Power Up
A7
Time since Alarm Initiated until Validated
A8
Probe to be used for Alarm Settings
Initial Setup Menu
Hor Real Time Hours
nin
Real Time Minutes
E0
Assignment of Digital Input
Off = Digital Input disabled
A1 = External alarm condition when short circuited
In = Door open if short circuited
DEF = Defrost Cycle initiated when shirt circuited
Ndf = Defrost Cycle will be bypassed when shirt circuited
RSt = Night Set Points used when short circuited
H0
Restore Factory Configuration
H1
Assign Master/Slave for Defrost Cycles
Mst = Sends signal through digital input to initiate slave controls to start
defrost
Slv = Performs defrost when receives defrost signal through digital input
(E0 = DEF when using master/slave operation)
H2
Keypad Password Protected
Yes = code is necessary to start/stop defrost or continuous cold cycle.
One minute after entering the code, keypad is locked again
No = Keypad not protected
H3
