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 designd 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.
Removing/Installing Thermostat
The thermostat hinges on tabs on the top of the subbase; no tool is needed to remove the thermostat from the sub- base. Pivot the bottom of the thermostat outward (releas- ing the snaps), then lift up to remove.
To replace it, first position the top tilted toward the wall bracket and align it until you feel the tabs and slots engage; then, while the top is in place, pivot the bottom toward the wall until the thermostat snaps into place.
Default Thermostat Settings
Default thermostat settings are in table 2 and the default program is shown in table 3.
