 Important Safety

•  This thermostat is designed for use with 24 Volt-AC low voltage single stage gas, oil or electric heating cooling systems, including single stage heat pumps (Model 500 only).
•  Do not use this thermostat on applications with voltage above 30 Volts AC.
• The system must have 24 Volt AC present for proper system operation and control.
• Wiring must conform to all building codes and ordinances as required by local and national code authorities
  having jurisdiction.
• This thermostat should only be used as described in this manual. Any other use is not recommended and will void warranty.

INSTALLATION

1.  Remove the cover of old thermostat and locate wire terminals. Do not remove wires from terminals yet.
2.  Use chart below to determine new terminal designations for new thermostat.
3. After labeling and removing all wires from terminals, unscrew the existing thermostat mounting base from wall. Be sure to secure wires to prevent them from slipping back into the hole in the wall.

 Installing Your New Thermostat

1.  Place system lever to OFF position, and fan control lever to AUTO position.
2.  Remove the front cover of the thermostat by firmly pulling it away from the base.
3. Place thermostat base against wall in the desired thermostat location and guide thermostat wires through
   vertical slot in base.
4. Mark placement of mounting holes as appropriate and drill using a 3/16” drill bit.
5. Gently tap supplied plastic anchors into the holes in the wall.
6.  Place the thermostat base against the wall in the desired location making sure the mounting holes are aligned and the thermostat wires are properly inserted through the slotted opening in the base.
7.  Fasten the base to wall using supplied screws.
8.  Connect wires to proper terminal screws using new terminal designations (see Wiring Diagrams section of manual).
9. Make sure all of the wire connections are secure and are not touching any other terminal to prevent electrical shorts and potential damage to the thermostat.
