POWER THE THERMOSTAT

You can choose from three methods to power the thermostat:

•

Batteries only (AAA alkaline).

• 24 Vac common wire only.

• 24 Vac common wire with battery backup (AAA alkaline).

NOTE: Battery backup prevents blank displays during power interruptions.

Wiring 24 Vac Common

• Single-Transformer System--Connect the common side of the transformer to the C screw terminal of the thermostat wallplate. Leave the metal jumper in place between Rc and R.

• T\,vo-Transformer System--Connect the common side of the cooling transformer to the C screw terminal of the thermostat waltplate. Remove the metal jumper between Rc and R.

Installing Batteries

Install two AAA alkaline batteries on the back of the thermostat as marked on the battery holder. See Fig. 14.

NOTE: After the thermostat is mounted on the wallplate, the thermostat does not require removal from the wallptate to replace the batteries. Refer to the enctosed Operating

Instructions, 69-1713, for more information on the removable battery holder.

MountThermostat to Wallplate

1.

Align the four tabs on the wallplate with the four slots on the back of the thermostat. Push the thermostat straight onto the wallplate until it snaps into place. See Fig 15.

Minimum-OffTimer Compressor

Protection

The TH5110 has an adjustable Minimum-Off Timer that can be set from zero to five minutes (Factory Setting-five minutes). The Minimum-Off Timer can be bypassed through the Installer System Test or it can be bypassed permanently by setting the Minimum-Off Timer to 0 minutes in the installer Setup.

The Minimum-Off Timer is activated after the compressor turns off.

If the thermostat is system powered (common wire), the

Minimum-Off Timer is also activated upon initial startup and after power interruptions.

If there is a call for cooling or heating during the

Minimum-Off Time, the thermostat flashes "Cool On" or

"Heat On "a. When the Minimum Off Timer expires, "Cool

On" or "Heat On" a appears solid in the display and the compressor and fan turn on.
