INTRODUCTION
The EZ Touch IR receiver will be required when the PTAC unit has been installed inside an enclosure
that does not allow direct line of sight between the digital controls and the wireless thermostat.
INSTRUCTIONS
1) If required, drill a 5/8” diameter hole on the front cover, approximately 3 inches below the top, or
the top panel of the enclosure, (See illustration next page)

2. OPERATING YOUR THERMOSTAT
1. ON/OFF key: switches the unit on or off. When the unit is off, all keys are invalid except ON/OFF keys.
2. MODE key: set up fan only, cooling or heating mode. Cycles as cooling ĺfan only ĺheating ĺcooling.
3. FAN key: set up fan speed. Cycles as high ĺlowĺauto ĺhigh.
4. °F/°C key: the temperature switches between Fahrenheit and Celsius degrees.
5. “UP”/”DOWN” keys: pressing "UP" or "DOWN" key once the display will show the current temperature
set point, if no key is pressed in 5 seconds the display will show the current room temperature. While the
display is showing the temperature set point, pressing the "UP" button once increases the temperature
set point by 1°C (or 1°F if in °F mode ), pressing the "DOWN" button once, decreases the temperature
set point by 1°C (or 1°F if in °F mode). Temperature set point range is 16°C~31°C (61°F~88°F).
6. LOCK and UNLOCK: pressing and holding both the "UP" and "DOWN" key for 3 seconds will lock or
unlock all keys except the ON/OFF key.
7. LCD display: displays the room temperature when the air conditioner is running. Pressing the "UP" or
"DOWN" key when key operation is valid will show the temperature set point, and will return to display
the room temperature after 5 seconds without any user action. After shutdown, the display shows OFF.

8. Backlight control: backlight is lit when pressing any operation key. Five seconds later will automatically
turn off.
9. Data Transmission Time Cycles: each time a key is pressed, the infra-red control unit will send the
signal of running mode, set point temperature, room temperature and fan speed to the control board;
when the unit is on: every 10 minutes (adjustable), see item 10, the infra-red control transmits room
temperature to the electronic control board; when the unit is off: the infra-red control will not transmit
any data.
10. Data Transmission Time Cycles Modification: while in shutdown state pressing and holding both
MODE and FAN keys for 3 seconds the LCD display will display the value of Data Transmission Time Cycle
in minutes (for instance, 10 means launch once every 10 minutes), press "UP" or "DOWN" keys to
change it (range between 1 and 20 minutes), press the MODE key or 10 seconds no key press to save
the change.
