Removing/Installing Thermostat
The thermostat hinges on tabs on the top of the sub-base;
no tool is needed to remove the thermostat from the
sub-base. Pivot the bottom of the thermostat outward
(releasing 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.
