What do the different symbols on the display mean?

How do I change the batteries?
Gently pull the thermostat off the wall plate, open the battery compartment on the back, replace the two AA batteries (alkaline recommended), and reattach the unit. Dispose of old batteries properly.
Why is my thermostat not responding?
First, check the battery level. If the display is blank, batteries may be dead. If the display is on but unresponsive, try pressing the reset button with a paper clip. If the issue persists, consult a technician.
Can I use the REV91 with a heat pump or electric heating?
