Installation Instructions
8. Mate the thermistors to the corresponding
interconnects on the main board. These will be
bundled with the 6-pin connector in the rooftop unit.
For ARC models, one connection will need to be
made (indoor coil sensor). For ARH models, an
additional connection will need to be made (ambient/
outdoor coil sensors).
9. Using wire connectors, connect 2 furnace wires
(blue and optional), 2 auto gen start wires (yellow,
optional, and only for RAREC1A and RAREC2A
controls), 3 thermostat wires (red, yellow, and black),
and two 12 VDC battery wires (red and black).
10. Rotate lower section of control box upwards making
sure not to crush any wires. Drive three screws,
securing he control box closed. The main control
install is now complete.
11. Remove the cover from the base by undoing the
two plastic snaps on the bottom of the base. A
small screwdriver or ballpoint pen can be used to
gently depress one snap at a time (reference the
figure on page 5).
12. Put thermostat base against the wall where you
plan to mount it. Make sure wires will feed through
the wire opening in the base of the thermostat.
13. With the base level, mark the placement of
themounting holes.
14 Ensure no other wires are affected by the drilling of
1/8” holes.
15. Using a 1/8” drill bit, drill pilot holes in the locations
you have marked for the wood screws.
16. Align thermostat base with mounting holes and
feed the control wires through the wire opening.
