TO SET THE COOL LIMIT STOP: Place the System Mode switch in the OFF

position, and the Set Slide switch in the RUN position. Press and hold the

DOWN button while sliding the System Mode switch from OFF to COOL. The

words “TEMP STOP” and “LOCK CODE” will appear on the screen, along with

two digits. Use the UP/DOWN buttons to select the proper code to access the

cool limit setting. Press the NEXT button to accept the setting. If the code

you tried was not correct, the thermostat will exit and return to the Normal

Run screen with no changes made. If the entered code is correct, the screen

will add the word “SET” and display the current cool set temperature limit.

Use the UP/DOWN buttons to adjust the minimum cool set temperature

value. Press the NEXT button to accept the setting and return to the Normal

Run screen in cool mode.

switch in the OFF position, and the Set Slide switch in the RUN position.

Press and hold the NEXT button for at least 5 seconds. The words “TEMP

STOP” and “LOCK CODE” will appear on the screen, along with two digits.

Use the UP/DOWN buttons to enter the current code (“00” by default) and

press the NEXT button one time. The word “SET” will now be displayed.

Use the UP/DOWN buttons to choose a new 2-digit code between “00” and

“99”. Press the NEXT button to accept the setting. The screen will flash

briefly to confirm the code change, and return to the Normal Run screen in

Off mode.

IF YOU FORGET YOUR TEMPERATURE STOP CODE: The code can be reset to

the factory default “00” by performing the following steps. Place the System

Mode switch in the OFF position, and the Set Slide switch in the RUN

position. Press and hold the NEXT and HOLD buttons together for at least

10 seconds. The screen will start flashing, and display words “SET”, “TEMP

STOP” and “LOCK CODE”, along with the new code of “00”. After a couple

seconds, the screen will automatically return to the Normal Run screen in Off

mode.

KEYPAD LOCKOUT: You can lock the front panel buttons to prevent

unauthorized tampering of your thermostat settings.

NOTE: These keypad lock instructions need to be performed in a timely

manner. The 4-button sequence which locks the thermostat must be entered

within a 10-second timeframe, or the keypad lockout sequence will have to

be entered again from the beginning.
