Installing or Changing the Batteries
To remove the battery compartment gently
squeeze the ribbed edges on both sides.
The battery compartment will pull down
from the thermostat body and will detach.
Install two AA batteries following the
polarity as shown inside the compartment.
Place compartment back into the
thermostat.
When the batteries are low the thermostat will enter a low battery mode.
Low battery mode has two levels.
• LEVEL 1: The low battery icon will be displayed.
The thermostat will continue to operate. Replace
the batteries as soon as possible
• LEVEL 2: The low battery icon will flash. If 24V AC is
present the thermostat will continue to operate if
the batteries are discharged or removed. If 24V AC
is not present the thermostat runs on batteries only
and THE SYSTEM WILL NOT OPERATE. Replace
batteries immediately.
Replace batteries if leaving thermostat unattended for more than 30 days.
