After the filter has been changed or maintenance per-
formed, reset the reminder by pressing the SETTINGS
button for 4 seconds at the corresponding reminder set-
tings screen. The screen will blink for a few moments to in-
dicate that the timer has been reset.
Service Indicator
When abnormal equipment operation is detected, the
SERVICE indicator will flash on the screen (see figure 17).
This indicates that the equipment requires service from a
qualified service technician.
Thermostat RESET
Under some abnormal conditions, it may be necessary to
the thermostat to its default condition. Such a RE-
SET would delete all programming and settings and there-
fore should only be used on rare occasions when the the thermostat fails to function as designed and/or as pro- grammed. Such an instance can occur as a result of a pow- er surge or similar electrical disturbance (e.g. after an elec- trical storm or power outage). The RESET button can be
used to recover from this situation.
CAUTION
When the RESET button is pressed, ALL settings re- vert back to the defaults, including the default pro- gram (see tables 2 and 3).
The RESET button is an unlabeled, recessed button lo- cated behind the door on the right−hand side of the thermo- stat, below the SETTINGS button (see figure 3). Use a pa- per clip or small pencil to press the RESET button; ALL thermostat settings will be reset to the defaults listed in the
Default Thermostat Settings section.
