Setting of High-Limit Function
The high-limit function is a safety feature that allows you to select the maximum temperature limit of the thermostat.
When this function is on, the thermostat will not allow heating settings to exceed the selected temperature limit. It is
recommended to refer to the specifications of your particular heating device and set up the high-limit function once
you installed the new thermostat.
To ENABLE the high-limit setting feature:
1. Press
▲
or
▼
to scroll to the desired high-limit temperature.
(This temperature will display in the program temperature pane on the LCD screen.)
2. Press USAGE and SET buttons at the same time for three seconds to activate high-limit
function at the set temperature.
(The LOCK symbol will appear to confirm that the high-limit feature is on.)
To DISABLE the high-limit setting feature:
1. Press the RESET button. (Remove the faceplate to locate the reset button. Press with a blunt object.)
(Clock will be reset and the lock symbol will begin flashing for five minutes.)
2. Press the USAGE and SET buttons at the same time when the lock symbol is flashing.
(When the LOCK symbol disappears the high-limit feature is off.)
Note: If a high-limit temperature is selected before programming, it will be the highest temperature you can set for
any of the program times.
If a high-limit temperature is selected after programming, any programmed temperatures set higher than the
new limit will be automatically reduced to the high-limit temperature.
