Troubleshooting
Air Conditioner Doesn’t Operate
1. Check there is power to the air conditioner. There is no power if the SAT-1’s
screen is blank.
2. Check the SAT-1 is on, i.e. the LCD display is on.
3. Check if symbol
is displayed. If so, checked that you are in the ‘switch on’
period, or alter the timer settings (refer to page 6).
Reduced Cooling or Heating
1. Check the SAT-1 is not in the SLEEP mode (refer to page 6).
2. Check to see if the air filter (if any) requires cleaning.
3. Check if any doors or windows are opened.
4. Check that there are no obstacles in front of the outdoor unit.
No Cooling or Heating
Check that the correct operating mode has been selected (Auto, Cool, Heat).
The preset temperature may have been set too high or too low. If the set
temperature appears okay, call for service.
Timer is Not Correctly Triggered
Check the clock is set to the right time (day light saving?) and the timer has been
correctly programmed.
Loss of Settings
If the SAT-1 fails to retain the preset timer settings when the power supply is off
then check the battery to see if it needs replacing. If the battery is flat, low or
missing, the LCD display will still operate, however the clock will reset to 0:00,
SUN settings.
The battery is located at the rear of the SAT-1. Separate the thermostat body
from the wall mounting plate by removing the screw attaching both pieces as
picture below.
Remove and check the battery. If necessary, replace with a lithium CR2032 cell
battery.
Remove the back cover
Use screw driver to
remove the locking
screw
Insert the battery into the
battery holder
