Introduction
Your temperzone air conditioner is supplied with a SAT-2 wall thermostat. This
thermostat has been designed to maintain a high level of comfort for room
occupants. Emphasis has been placed on providing controls that are easy to use
despite the sophisticated microprocessor system that runs it. Use of the Auto and
Timer function settings allows you “to set it and forget it”.
Features Summary
●Cool/Fan modes.
●Heat/Auto modes (Reverse Cycle Systems only).
●Backlighting display with different colour indicating different mode of operations.
●Auto/High/Medium/Low fan speed selection.
●Temperature setting range from 16ºC to 30ºC.
●Room temperature display.
●Real time clock.
●7 days programmable (Start/Stop) timer that programs the unit to two start/stop
sessions per day.
●Bypass function enables user to bypass the on/off button and any user
programmed times for immediate operation of the air conditioner.

real time clock and the integrity of the control’s data. When power is resumed
(returned/switched on again), the unit will automatically restart using the last
settings.
●Key lock function prevents unauthorized personnel from changing the settings

Two sessions of on and off timer per day being set as follow:
P1 on timer
0800
P1 off timer 1200
P2 on timer 1300
P2 off timer 1700
If current time is 0730 hrs, it will remain as last state. At 0800 hrs, it will turn on the
unit using P1 on timer. At 1200 hrs, it will turn off the unit using P1 off timer. At 1300
hrs, it will turn on the unit using P2 on timer. At 1700 hrs, it will turn off the unit using
P2 off timer.
Pressing on/off button to on/off the unit will bypass the control of current event. The
second event will take over upon expiry of current event.
Example: If user turns off the unit at 1000 hrs, it will remain off until 1300 hrs, at
which time control is taken over by timer P2.

Troubleshooting
Air Conditioner Doesn’t Operate
1. Check there is power to the air conditioner. There is no power if the SAT-2’s
screen is blank.
2. Check the SAT-2 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-2 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.
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-2 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-2. 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.
Use screw driver to
remove the locking
screw
Remove the back cover
Insert the battery into the
battery holder
Page 11
Keypad Will Not Respond
Check to see if key lock symbol is displayed. Refer to page 7 for unlocking
procedure.
Remote Control Doesn’t Operate
1. Check the batteries in the remote control aren’t flat.
2. The infra red remote control must be pointed directly at the SAT-2 wall
thermostat plaque in order for its signal to be received.
3. If there is no light or beep from the wall plaque when the remote controls
buttons are pressed, consult your installer to ensure the wall plaque has been
set up correctly for remote control use.
