● Press “PRG” and “SEL” simultaneously until “0" appears (it will start flashing).

● Use the “ARROW” keys to scroll to “77".

● Press “SEL”. “C 0" will now appear and begin flashing.

● Use the “ARROW” keys to scroll to the desired parameter (as identified below).

● When the parameter is displayed, press “SEL” to show the currently programmed

setting.

● Use the “ARROW” keys to alter the parameter setting.

● Press “SEL” first, then “PRG” to retain the new setting.

Most Common Settings:

For standard refrigerator/freezer thermostats or ARCTIC AIR thermostats

● Change “C 18” from “0” to “1” (if you want your control to display the temperature

F rather than

C.).

● Change “C 13" from “0” to “1” (only if you have the optional box temperature probe

connected).

Use the procedures described in the next section to set the appropriate “setpoint” and

“differential”.

For ECM thermostats

● Change “C 18” from “0” to “1” (if you want your control to display the temperature

F rather than

C.).

● Change “C 13” from “0” to “1” (only if you have the optional box temperature probe

connected).

● Change “C 33” to “1” (parameter MUST be “1”).

● Change “C 36” to “100” (parameter MUST be “100”).

● Change “C 37” to “-100” (parameter MUST be “-100”).

Use the procedures described in the next section to set the appropriate “setpoint” and

“differential”.

List of all settings: While they may not be required, the following pages offer a description of

the other, less often used, control settings.

Parameter “C 13" - Probe Display (Default = “0” with one Probe, “1” w/optional Box Probe)

For use only when the optional box temperature probe is added, select either “0” to display the

Plate Probe or, “1” to display the box probe. In both cases, pressing the down “ARROW” key

displays the other probe value.

Parameter “P 14" - Calibration Offset (Default =”0.0”)

Introduces an error offset to the temperature probe.

Parameter “C 17" - Probe response time (Default = “5”)

Changes probe response time for noise filtering

Parameter “C 18" - Display Units

C or

F (Default = “1”)

Changes units to degrees Centigrade (“0”) or Fahrenheit (“1”). Don’t forget, the “setpoint” and

differential” values must also be programmed appropriately.

Parameter “P 25" - Low Alarm Limit (Default = “-50”)

An audible alarm is sounded if the temperature falls to this limit.

Parameter “P 26" - High Alarm Limit (Default = “90”)
