Insert Batteries Into the Thermostat
The thermostat can be powered by battery or
24 VAC. If a wall transformer is used to power
the thermostat, connect between C and RH.
Ensure the batteries are installed following the
specified polarity markings on the thermostat.
CAUTION: Special Battery Warning
• Always replace the batteries as soon as you have
low battery levels, indicated by "LOW" then "BAT"
flashing on the display. If the batteries drain, the
thermostat could leave the HVAC system on,
overheating or freezing the home.
• Always replace the batteries at least once a year.
This will protect the thermostat from damage and
corrosion by leaking batteries.
• If the home is unoccupied for a month or more,
such as vacation homes, you should replace the
batteries as a preventive measure against battery
failure while you are away.
• Always use new batteries as replacements.

To control the fan manually on the Alarm.com ADC-T2000 thermostat:

1. Put the thermostat in Off mode by pressing the button until no heating or cooling symbols are displayed. This means the system is not heating or cooling but still powered on.

2. Use the fan control option (available through the thermostat or Alarm.com app) to switch the fan mode. You can set it to:
- Auto: Fan runs only when heating or cooling is active.
- On: Fan runs continuously to circulate air.

To turn the fan off manually, set the fan mode to Auto and ensure the thermostat is in Off mode. This prevents the fan from running unless needed for heating or cooling.
