FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY
BEFORE INSTALLING OR OPERATING THIS CONTROL COULD CAUSE
PERSONAL INJURY AND/OR PROPERTY DAMAGE.
This sequencer is a direct replacement unit for sequenc-
ing both fan and heat. This sequencer has a solid-state
24 volt heater between the "H-H" terminals and a variety
of normally open contact sets. These contacts close and
open within specified timings and are used to control the
furnace fan and heating elements on demand from a
room thermostat.
THIS CONTROL MUST BE INSTALLED BY A QUALI-
FIED INSTALLER.
All wiring must conform to local and national electrical
codes and ordinances.
This control is a precision instrument, and should be
handled carefully. Rough handling or distorting compo-
nents could cause the control to malfunction.
This control has been accurately calibrated at the factory.
Any attempt to re-calibrate this control will void the White-
Rodgers warranty.
WARNING
!
Do not use on circuits exceeding specified volt-
ages. Higher voltages will damage control and
could cause shock or fire hazard.
If in doubt about whether your wiring is millivolt,
low or line voltage, have it inspected by a quali-
fied heating and air conditioning contractor or a
licensed electrician.

INSTALLATION INSTRUCTIONS
Some sequencers contain auxiliary contacts that are
used to energize the heater of another sequencer. This
arrangement provides a definite delay in energizing heat-
ing elements and prevents more than the required num-
ber of elements from being energized at the same time.
It also allows one room thermostat to control a large
number of elements without excessively high current
through the thermostat.
CAUTION
!
To prevent electrical shock and/or equipment
damage, disconnect electric power to system at
main fuse or circuit breaker box until installation
is complete.
Label all wires prior to disconnection when ser-
vicing controls. Wiring errors can cause improper
and dangerous operation.
Following installation or replacement, follow
appliance manufacturers' recommended instal-
lation/service instructions to insure proper op-
eration.
