begin with pre-purge, allowing single or multiple trials for ignition
depending on model. If burner relights, normal operation
resumes, if burner does not relight, control will go into lockout
as described in “failure to light”.

Fault Conditions

The LED will flash on for 1/4 second, then off for 1/4 second during
a fault condition. The pause between fault codes is 3 seconds.

MOUNTING AND WIRING

The Series 35-60 is not position sensitive and can be mounted
vertically or horizontally. The case may be mounted on any surface
with #6 sheet metal screws.

The control must be secured in an area that will experience
minimum vibration and remain below the maximum operating
temperature of 160°F.

All connections should be made with UL approved 105°C rated
18 gauge, stranded, .054 thick insulated wire. Refer to wiring
diagram when connecting the Series 35-60 to other components
in the system.

CAUTION:

Label all wires prior to disconnection when servicing controls.
Wiring errors can cause improper and dangerous operation.
A functional checkout of a replacement control is recommended.

Start up - Heat Mode

When a call for heat is received from the thermostat supplying
24 volts to TH, the control will reset, perform a self check
routine, flash the diagnostic LED, and a pre-purge delay begins.
Following the pre-purge period the gas valve is energized and
sparks commence for the trial for ignition period.

When flame is detected during the trial for ignition, sparks are
shutoff immediately and the gas valve remains energized. The
thermostat and main burner flame are constantly monitored to
assure the system continues to operate properly. When the
thermostat is satisfied and the demand for heat ends, the main
valve is de-energized immediately.

Failure to Light - Lockout

SINGLE TRIAL MODEL

Should the main burner fail to light, or flame is not detected
during the trial for ignition period, the control will go into lockout
and the valve will be turned off immediately.

MULTI TRIAL MODEL

Should the main burner fail to light, or flame is not detected
during the first trial for ignition period, the gas valve is
de-energized and the control goes through an interpurge delay
before another ignition attempt. The control will attempt two
additional ignition trials before going into lockout and the valve
relay will be de-energized immediately.

Recovery from lockout requires a manual reset by either
resetting the thermostat for a period of 5 seconds.

If the thermostat is still calling for heat after one hour the control
will automatically reset and attempt to ignite the burner again.

Flame Failure - Re-Ignition

If the established flame signal is lost while the burner is
the control will respond within 0.8 seconds. The HV spark
will be energized for a trial ignition period in an attempt to
relight the burner. If the burner does not light the control
will de-energize the gas valve. Multi-try models will make
two more attempts to relight the burner. If the burner
does not relight the control will go into lockout as noted
above in “Failure to light”. If flame is re-established,
normal operation resumes.

Recycle After Loss Of Flame

The option “recycle after loss of flame” may be selected as a
special feature. With this option, upon loss of flame, the gas
valve is de-energized and the control recycles its sequence of
operation. Controls with no prepurge will begin with the first trial
for ignition period. Multi-try models will allow three tries for
ignition including interpurges. Controls with pre-purge delay will
