SYSTEM OPERATION - VERSION 2 CONTROLLER
Initial Start-Up:
When power is applied to the unit, the control will briefly display all symbols, and the Compressor symbol will be displayed (if
unit is calling for cooling). There may be a brief delay prior to the evaporator and condenser fans turning on.
Set Point:
The set point is set from the factory at 55°. It can be adjusted by the customer between 50° and 70° in one degree increments.
Cooling Operation:
Cooling is activated once the air sensor probe senses a temperature that is four degrees greater than the set point. The controller
then energizes the compressor relay which activates the compressor, evaporator fans and condenser fans. The unit provides cool-
ing until the air sensor probe senses the set point. At this point the compressor relay is de-energized which stops the compressor,
evaporator fans, and condenser fans.
Defrost:
After two hours of compressor operation the controller will activate defrost. The compressor relay will de-energize, stopping the
compressor, evaporator fans, and condenser fans. The compressor relay will remain de-energized for five minutes, and then the
unit will return to normal operation. The set point and the dripping snowflake will be displayed during defrost and until the unit
reaches set point after a defrost cycle.
Display:
The Set point is displayed by default. The air sensing probe temperature can be accessed by pushing the set button and scrolling
through PB1 and set point parameters.
Safety Features:
Once the compressor relay is de-energized the controller must wait 5 minutes before re-energizing the relay. This prevents the
compressor from repeatedly turning off and on. If the unit is calling for cooling during this time, the compressor symbol will
blink indicating that cooling is needed but the control is waiting for the anti-short cycle delay.
In the event of a faulty air sensing probe, the compressor will cycle off for 10 minutes and on for 40 minutes. E1 will be displayed
on the screen.
Alarms:
The high temperature alarm (AH1) will be displayed if the room temperature reaches 10 degrees above the set point. The alarm
will reset once the temperature drops by 2 degrees. This alarm will only be active 10 hours after the unit is turned on and will be
disabled for an hour after an anti-frost cycle.
The low temperature alarm (AL1) will be displayed if the room temperature reaches 10 degrees below the set point. The alarm
will reset once the temperature increases by 2 degrees. This alarm will only be active 10 hours after the unit is turned on. And
will be disabled for an hour after a defrost cycle.
E1 will be displayed in the event of a thermostat probe failure.
Confirm if you have a Version 2 Controller using the above illustration
as a guide. If Your controller does not match this illustration than you
have a Version 1 Controller featured on page 18.
