Service Indicator
When abnormal equipment operation is detected, the SERVICE indicator will flash on the screen (see figure 16). 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.
