Introduction
Your temperzone air conditioner is supplied with a TTS-11 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 / Dry / Fan modes.
• Heat / Auto modes (Reverse Cycle systems only).
• Auto / High / Medium / Low fan speed selection.
• Temperature setting range from 16°C – 30°C .
• LED to indicate status of the unit (Power On/Off).
• Room temperature display.
• Real time clock.
• 7 days programmable [Start/Stop] timer that programs the unit to two start/stop
sessions per day. The timer can also be set for a single regular session time over
an entire 7 day period.
• Bypass function enables user to bypass the on/off button and any user
programmed times for immediate operation of the air conditioner.
• Battery backup. In the event of a power failure a backup battery will maintain the
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 unauthorised personnel from changing the settings of
the Wall Thermostat.
• Sleep function.
• Air swing function.
• Infra Red remote controller (option)

Troubleshooting
Air Conditioner Doesn't Operate
1. Check there is power to the air conditioner. There is no power if the TTS-11's
screen is blank.
2. Check the TTS-11 is on, i.e. the yellow On/Off light is lit.
3. Check if 'TIMER ACTIVE' is displayed. If so, check that you are in the
'switch on' period, or alter the timer settings (refer page 6).
Reduced Cooling or Heating
1. Check the TTS-11 is not in the SLEEP mode (refer page 7).
2. Check to see if the air filter (if any) requires cleaning.
4. Check if any doors or windows are open.
3. 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 (daylight saving?) and the timer has been
correctly programmed.
Loss of Settings
If the TTS-11 fails to retain the preset
temperature and timer settings when the
power supply is off then check the
battery to see if it needs replacing. If the
battery is flat or missing, the LCD
display will still operate, however the
letters 'OP' appear briefly (1-2 seconds)
when the controller is powered on.
When the batteries are low, the time
settings default to:
Monday, 12am, Cool
cycle, 25°C setpoint and Low fan speed.
Note: If the controller is connected to
the power via an external time clock
where the power is disconnected frequently (e.g. daily) then the backup battery will
have a reduced life.
The battery is located at the rear of the TTS-11. Separate the thermostat body from
the wall mounting plate by inserting the tip of a small flat screwdriver in the slot at
the bottom centre of the thermostat body. Press vertically up (gently) against the
holding catch. This will disengage the bottom of the thermostat body from the wall
mounting plate and allow it to be lifted free. Remove and check the batteries.
If necessary, replace with two AAA 1.5V batteries, preferably Energiser.

Operation (cont'd)

Sleep Activation
Press [SLEEP] button to activate the Sleep option. This option saves energy by
altering the set temperature over a two hour period.
Example Uses:
In Summer, before going to bed at night with the Cool mode set, pressing the
[SLEEP] button gradually raises the set temperature by 2 degrees to compensate
for a person's lower body metabolism when sleeping.
In Winter, with the Heat mode set, pressing the [SLEEP] button gradually lowers the
set temperature by 2 degrees to compensate for heavier Winter bedding.
The Sleep option is only available for Cool, Heat and Auto modes.
Key Lock
This feature protects the control from being tampered with by children or
unauthorised persons.
To activate, press the [MINUTE] button three times quickly. 'Key Lock' will appear on
the display. When the Key Lock is active the [ON/OFF] and [FAN] buttons can still
be used. To cancel the 'Key Lock' function press the [MINUTE] button three times
again. 'Key Lock' will no longer be displayed.
Bypass
This feature provides a quick 'on demand' alternative to the 'pre-programmed' type
of use. Bypass operation permits the user to start the air conditioner immediately,
bypassing the ON/OFF button and any programmed session times.
Bypass is initiated by pushing the [HOUR] button:
– once for 1 hour operation
– twice for 2 hour operation
– three times for 4 hour operation
– four times to cancel.
The display shows how many hours have been selected, ie
H1, H2
or H4.
To terminate
H1, H2
or
H4
before the chosen time has finished, press the [HOUR]
button until
H4
disappears. The 'on demand' timer is now turned off and so is the air
conditioner.
During Bypass operation the LED light will flash.
