Setting the HIGH-LIMIT FUNCTION
To enable this feature and set a maximum temperature, first press the "UP" or "DOWN" key until the
desired high limit temperature is shown in the program temperature pane. Press the “USAGE” and
“COPY” keys for 3 seconds to activate the function. A LOCK symbol will be shown.
All existing programs will be scanned, and if the existing temperature setting is above the new maximum
set point, it will be reduced to the high-limit set point. The High-limit setting can not be bypassed by
programs, temporary overrides or the HOLD function.
To deactivate the function, turn the unit off for at least 30 seconds, and then turn it on. The LOCK
symbol will blink for 5 minutes. While the LOCK symbol is blinking, the deactivation process can be
carried out by pressing “USAGE” and “COPY” keys for 3 seconds. The LOCK symbol will disappear
upon deactivation.
