STEP 5 - Testing
All Models with Red (Low Water) and Amber (Test) Lights
OFF
ON
a. Before filling the system,
turn on the electric power
to the boiler. Set the room thermostat to "heat".
For Series PS-801
the burner will come on briefly
(10 second or less) and then shut off which verifies
proper operation. The burner
will not
operate without
water in the system. The low water cut-off's red LED
should be illuminated.
For Series PS-851
the burner will come on briefly
and then shut off, verifying proper operation. The
burner
will not
operate without water in the system.
The low water cut-off's red LED should be illuminated.
b.
Fill the system with water.
For Series PS-801
the low water cut-off's red LED
should shut off in about 15 seconds, after the water
contacts the probe.
For Series PS-851
the low water cut-off's red LED
should shut off after the water contacts the probe.

c.
Hold the test switch (AA) down while noting the
amber LED (BB) on top of the control housing (G).
1.
If the amber LED (BB) glows dimly,
the water
level is above the probe.
2.
If the
amber LED (BB) is off,
the water level may
be below the probe or the water is too pure and
may require the addition of boiler water treatment.
3.
If the
amber LED (BB) glows brightly,
it could indi-
cate a grounded (non-operable) probe. If this is
the case, proceed to "Troubleshooting".
AA
d.
Test for correct burner circuit wiring.
1.
Hold down the test switch (AA) while the burner
is running for more than:
• 12 seconds for PS-801
• 2 seconds for PS-851
2.
If the burner shuts off while the test switch is
depressed, the burner circuit is wired correctly.
