Oil Primary Specifications - Wayne HS Manual

OIL PRIMARY SPECIFICATIONS

The 101343-SER Electronic Oil Primary is a line voltage,
safety rated, oil primary control for residential oil fired
burners used in boilers, forced air furnaces and water
heaters. The 101343-SER used with a cad cell flame
sensor, operates an oil burner and optional oil valve. The
primary controls fuel oil delivery, senses flame, controls
ignition spark (either interrupted or intermittent) and notifies
a remote alarm circuit when in lockout.
The 101343-SER can be used with both hydronic and
forced air systems. When used with hydronic systems, line
voltage switching Aquastat® Controllers normally provide
for the starting and stopping of the combustion sequences.
With forced air systems, both mechanical and electronic low
voltage thermostats control the starting and stopping of the
combustion process.
The 101343-SER is intended for use only on oil burning
appliances, which do not require pre-purge and post-purge
as a safety related function as defined in UL296. The valve-
on delay and burner motor-off delay in this control are
intended only to help establish draft and reduce oil after-drip
related problems.
The 101343-SER can be used with EnviraLink
systems and hand-held diagnostics, such as, the QuickLook
72 by OnWatch. http://www.onwatchinc.com/

FEATURES
Thermostat(s)
The oil primaries are compatible with both standard
thermostats and EnviraCOM™ communicating thermostats.
Limited Recycle
This feature limits the number of recycle trials (for each call
for heat) to a maximum of three trials. If the flame is lost
three times and does not successfully satisfy a call for heat,
the 101343-SER locks out.
Pump Priming Cycle
To facilitate purging air from the oil lines and filters, the
101343-SER can be placed in a purge routine. The purge
routine is started by pressing and releasing the reset button
within 15 seconds after the burner motor starts. The lockout
timing will be extended to four minutes and the ignition set
in the intermittent mode for this cycle only. The 101343-SER
automatically reverts to its labeled interrupted and safety
switch timing states (as applicable).
The pump priming cycle can only be entered if there have
been no lockout occurrences since the last successful heat
call. To reset the device so that the pump priming cycle can
be entered, press and hold the reset button until the light
emitting diode (LED) flashes (approximately 30 seconds).
Data Port
Controls are designed to allow networking and upgrade
modules to be added in the field by simply plugging them
into the data port/network
Disable Function
Pressing and holding the reset button will disable all
functions until the button is released. The 101343-SER will
restart at the beginning of the normal heat cycle on safety
check.
Limited Reset (Restricted Mode)
In order to limit the accumulation of unburned oil in the
combustion area, the control can only be reset three times.
The reset count returns to zero each time a call for heat is
successfully completed.
®
monitoring
To reset from restricted mode: Press and hold the reset
button for 30 seconds. When the LED flashes once for one
second, the device has reset.
Lockout Mode
The 101343-SER will enter the lockout mode when:
• Flame is detected during valve-on delay.
• When flame is not established during Trial for Ignition.
• When flame is lost three times in one call for heat.
• When flame is detected during burner motor-off delay
period.
Diagnostic LED
The diagnostic LED has four states:
1. On-Flame present.
2. Off-No flame.
3. Two seconds on, two seconds off-Recycle.
4. 1/2 second on, 1/2 second off-Lockout.
Cad Cell Resistance
Cad cell resistance can be checked without using an
ohmmeter. During the run mode, press and release the
reset button. The resulting flashes indicate the resistance.
