Parameter Description
Compressor / Set Point Menu
SEt
Sets the Ambient Temperature set point between r1 and r2
r0
Differential or hysteresis for set point
(For d0 = re)
Ambient temperature ≥ SEt + r0
Output On
Ambient temperature ≤ SEt
Output Off
(For d0 = in)
Ambient temperature ≤ SEt - r0
Output On
Ambient temperature ≥ SEt
Output Off
r1
Minimum value for set point
r2
Maximum value for set point
c0
Minimum time compressor must remain off before being
restarted
c1
Duration of cold cycle
c2
During probe error, time that output is engaged
c3
During probe error, time that output is disengaged
c4
Minimum time compressor must stay on
c5
Minimum time between compressors starts
Defrost Menu
d0
Selection for Heating or Cooling Operation
re = Cooling
in = Heating
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.
d11
Minimum duration the control remains in defrost cycle.
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.
HdE Hours until next defrost cycle.
ndE Minutes until next defrost cycle.

3 seconds. Then, use arrows to select day. Press set to store
day; use arrows to access month and year
td
The display refreshes at 1 degree if actual temperature is
greater than 1 degree higher td seconds before during defrost
and open door conditions
