Operating Instructions
TIMER FUNCTIONS
Follow these steps to program the Auto-on or Auto-off feature using the control panel:
Auto-off:
1. When the unit is on, press the Timer button to activate the Auto-off timer. The Auto-off indicator
light will illuminate.
2. Press or hold the ( ) and ( ) buttons to change the ‘Auto’ time by 0.5 hour increments, up to
10 hours, then at 1 hour increments up to 24 hours. The unit display will count down the time
remaining until start.
3. Within 5 seconds of setting auto-off time, press the Timer button again to complete the auto-off
program.
Auto-on:
4. When the unit is off, press the Timer button to activate the auto-on program. Set the auto-on time
as in step 2 above. Within 5 seconds of setting auto-on time, press the Timer button again to
complete the auto-on program.
Note:
Turning the unit ON or OFF at any time or changing the on/off timer setting to 0.0 will cancel
the timer settings.
AUTO-RESTART
If the unit shuts off unexpectedly due to a power outage, it will restart with the previous function set-
tings automatically when the power resumes.
MEMORY SETTING
Each time the unit is disconnected / re-connected and/or in the event of a power failure, the elec-
tronic circuit board automatically defaults to the last program setting that was used. After the unit has
stopped, it may take several minutes before operating conditions resume.
AUTOMATIC DEFROST
If the unit is operating in an environment where the ambient temperature is very cold, frost may form
on the evaporator coils. The compressor will cycle off but the fan will continue to run until the frost
melts. An error code may show on the control panel display.
When the frost has melted, the compressor function will resume and the unit will return to regular
operation.
To ensure frost does not form on the evaporator coils, ensure the ambient temperature around the
unit is at a comfortable level. Higher ambient temperature will also help to remove humidity from the
air.
