AHE-100-02S Hydronic Heating System Service Manual—Rev. B
Diesel-Burner Controller:
The diesel-burner controller operates all the compo-
nents of the diesel-burner head and safely shuts the
heater
OFF
in the event of an overheat, flameout,
and low voltage condition. It also receives diesel-
burner operation status signals from the flame sen-
sor, VDC control thermostat, and VDC high-limit
thermostat.
Component Test:
The following conditions must exist prior to per-
forming the diesel-burner controller circuit tests on
the following page. If one of the conditions below
does not exist, please contact our technical support
department at 1-800-685-4298 for additional assis-
tance.
Condition #1
A battery voltage level between 11.5 to 14.0 volts
DC must be present at the diesel-burner controller
during all testing. It may be necessary to perform a
voltage check to ensure that this condition exists.
To perform the voltage check, locate the diesel-
burner controller’s B-plug, and insert the probes of
a DC voltmeter into the B-4 (+) and B-2 (-) loca-
tions.
Condition #2
A voltage level of between 11.5 to 14.0 volts must
be present at the diesel
ON/OFF
switch circuit of
the diesel-burner controller during all testing. It
may be necessary to perform a voltage check to
ensure that this condition exists. To perform the
voltage check, locate the diesel-burner controller’s
B-plug, and insert the probes of a DC voltmeter into
the B-1 (+) and B-2 (-) locations. Turn the diesel
switch
ON
and observe the voltage level.
Ground Circuit Test:
Locate the diesel-burner controller’s B-plug and C-
plug. Insert the probes of a DC voltmeter into the B
-4 (+) and C-5 (-) locations and turn the diesel
switch ON. If a voltage reading does not register on
the voltmeter, the diesel-burner controller must be
replaced. If voltage is present, proceed to the next
circuit test.
VDC/VAC Control Thermostat Circuit Test:
Locate the diesel-burner controller’s B-plug and C-
plug. Insert the probes of a DC voltmeter into the C
-1 (+) and B-2 (-) locations and turn the diesel
switch
ON
. If a voltage reading does not register on
the voltmeter, the diesel-burner controller must be
replaced. If voltage is present, proceed to the next
circuit test.
VDC High-Limit Thermostat Circuit Test:
Locate the diesel-burner controller’s B-plug and C-
plug. Insert the probes of a DC voltmeter into the C
-4 (+) and B-2 (-) locations and turn the diesel
switch
ON
. If a voltage reading does not register on
the voltmeter, the diesel-burner controller must be
replaced. If voltage is present, proceed to the next
circuit test.
Motor Circuit Test:
Locate the diesel-burner controller’s B-plug and C-
plug. Use a jumper wire to make a connection from
the C-1 location to the C-7 location. Turn the diesel
switch
ON
and insert the probes of a DC voltmeter
into the C-2 (+) and C-5 (-) locations. If no voltage
reading registers on the voltmeter, the diesel-burner
controller must be replaced. If voltage is present,
proceed to the next circuit test.
Be sure to remove the jumper wire that was used to make the
connection from the C-1 location to the C-7 location. A fail-
ure to do so will result in an overheating condition during
normal operation.
Ignition Coil Circuit Test:
Turn the diesel switch
OFF
and locate the diesel-
burner controller’s C-plug. Also, locate the VDC
high-limit thermostat and disconnect it’s 2-way
male plug from the (white plastic) 6-way female
connector. Insert the probes of a DC voltmeter into
the C-8 (+) and C-5 (-) locations and turn the diesel
switch
ON
. If a voltage reading does not register on
the voltmeter 18-25 seconds after the initial start-up
the diesel-burner controller must be replaced.
NOTE:
Be sure to reconnect the VDC high-limit thermo-
stat’s wires to the thermostat. The diesel-burner
will not ignite during normal operation if the VDC
high-limit thermostat is left disconnected.
