INSTALLATION
MOUNTING AND WIRING
WARNING
!
Do not use on circuits exceeding specified voltage.
Higher voltage will damage control and could cause
shock or fire hazard.
CAUTION
!
To prevent electrical shock and/or equipment dam-
age, disconnect electric power to system at main fuse
or circuit breaker box until installation is complete.
Failure to earth ground the appliance or reversing the
neutral and hot wire connection to the line can cause
shock hazard.
Shut off main gas to heating system until installation
is complete.
Route and secure all wiring as far from flame as practical
to prevent fire and/or equipment damage.

NOTE: Program keys are lettered and color coded.
NOTE
Replace control as unit –no user serviceable parts.
All wiring should be installed according to local and national
electrical codes and ordinances.
The control may be mounted in any orientation on a
convenient surface using two #6 x 5/8" sheet metal screws.
If desired, control can be mounted on a 4" x 4" junction
box using two #8-32 x 5/8" machine screws. The control
must be secured to an area that will experience a minimum
of vibration and remain below the maximum ambient
temperature rating of 175°F. The control is approved for
minimum ambient temperatures of -40°F.
Refer to the wiring diagrams and wiring table when
connecting the control to other components of the system.
UL approved 105°C rated 18 gauge minimum wire is
recommended for all low voltage connections. UL approved
105°C rated 16 gauge minimum wire is recommended
for all line voltage connections. Refer to table below for
recommended terminals to mate with those on the control.
After installation or replacement, follow appliance
manufacturer's recommended installation/service instructions
to insure proper operation.
