around the bottom edge of the base.

STEP TWO
MOUNTING THE BASE
The thermostat should be installed on an interior wall of the desired zone approximately 5’ (1.5
m) above the floor. Do not mount the thermostat in a location that may be affected by localized
heat sources or cold drafts. It may be necessary to install a draft barrier behind the thermostat to
prevent air from blowing through the wiring hole and affecting the thermostat’s built-in sensor.
Mount the base directly to the wall using two #6
1” screws. The screws are inserted through the
mounting holes and must be securely fastened
to the wall. If possible, at least one of the screws
should enter a wall stud or similar surface. If the
thermostat is to be mounted to a 2” x 4” electrical
box, order an Adaptor Plate 007. This plate mounts
to the electrical box and the thermostat mounts to
the plate. Ensure that the electrical box does not
provide cold air to the thermostat.
NOTE: If the 508 is to be used for remote sensing (i.e. The built-in air sensor is disabled
and an indoor sensor is being used.) Mount the thermostat in the desired location in an
appropriate manner.
STEP THREE
ROUGH IN WIRING
• 18 AWG or similar wire is recommended for all 24 V (ac) wiring.
• All wires are to be stripped to 1/4” (6 mm) to ensure proper connection to the control.
• Run wires from the 24 V (ac) power to the thermostat. Use a clean power source to
ensure proper installation.
• Run wires from the heating device to the thermostat.
