BATTERY ELIMINATOR (optional accessory) - t
supply adaptor is used to power the thermostat and eliminate the need
for replacing batteries each year. Use only the Venstar accessory
ACC0800 for proper operation.
LOW BATTERY WARNING - The two AA lithium batteries must be replaced
at least once every 12 months to ensure proper operation. The “low
battery” icon (fig. 1) will appear on the display when it is time to replace
the batteries.
When the “low battery” icon is displayed the batteries must be replaced
immediately (see next page). The manufacturer cannot be liable for
improper operation of the thermostat if the batteries are not immediately
replaced. Annual battery replacement is especially critical in locations
subject to freezing temperatures. The thermostat will be unable to turn
on the heating system if the batteries are exhausted.

BATTERY REPLACEMENT - To replace the batteries:
Separate the thermostat from the backplate by pulling the top of the backplate with one hand while pulling on the top corner of the thermostat with
your other hand.
Then turn the thermostat over to remove the batteries
from the holder and replace with AA Lithium batteries.
You may experience improper operation with the use
of alkaline batteries.
Note: After replacing the batteries,
two dashes will appear momentarily
