NOTE: The Temperature Limit Stop settings need to be performed in a timely manner, as the thermostat will timeout and automatically exit the setting screens after approximately 10 seconds without a button press.
The following examples are shown for setting the maximum set temperature for Heat mode. Setting the Temperature Limit Stop for Cool mode is done in the same exact manner with the System Mode switch in the Cool position, and instead you will be setting the minimum set temperature for cooling. Once a Temp Stop Lock Code has been selected, this same code is used for both Heat and Cool temp stops.
TO SET THE TEMPERATURE LIMIT STOP: Press the MENU button, then press the SCROLL button until “SET HEAT TEMP STOP” is shown, then press the OK button. The words “ENTER CODE” and “TEMP STOP” will appear at the top of the screen, along with two digits at the left. Use the UP and DOWN buttons to enter the current Temp Stop Lock Code (“00” by default). Press the NEXT button to advance. If the code entered does not match the current Temp Stop Lock Code, the words “WRONG CODE” will flash briefly, and you may try to enter the correct code again. If the current code has been entered correctly, you will have the ability to change the desired Temp Stop Lock Code to something else. The words “SET CODE” and “TEMP STOP” will appear at the top of the screen, along with two digits at the left. Use the UP and DOWN buttons to enter the desired Temp Stop Lock Code to be used, and press the NEXT button to advance.
The words “SET HEAT RANGE STOP” will appear at the top of the screen, along with two large temperature digits in the middle. Use the UP and DOWN buttons to adjust the desired maximum heat set temperature value (or minimum set temperature value for Cool mode). Once complete, press the NEXT button to accept the setting and return to the Normal Run screen.
IF YOU FORGET YOUR TEMPERATURE STOP LOCK CODE: The code can be reset to the factory default “00” by performing the following steps. Start with the System Mode switch in either the Heat or Cool positions, then change to the OFF position. Press and hold the HOLD, NEXT, and OK buttons all at the same time for at least 10 seconds. The screen will briefly show “00” on the screen to confirm that the Temp Stop Lock Code has been successfully reset to the factory default of “00”.
