Thermostat Operating Instructions
The T511 thermostat is factory programmed to automatically recognize the state of your HVAC system and to control damper
operation for cooling or heating needs. The digital display thermostat has a minimum fixed deadband of 3 degrees. For the most

LOWER

automatically maintains the 3-degree deadband.
If your thermostat is installed with backup batteries for the display, a
LOW BATTERY WARNING

(2) AAA batteries about two months before the batteries are depleted. Replace with new alkaline batteries. All thermostat settings
are stored in permanent memory and do not require battery power for retention.
To access the batteries, press down on the top right hand corner of the thermostat and pull the battery pack out the side. Reverse
the procedure to install the battery pack.
