Fuse Operation
There are two (2) fuses associated with the Trinity Ts
controller. Check this fuse before replacing the
controller or any other electrical component. If the fuse
is blown, it will prevent the protected device(s) from
functioning. Check the
condition
of the fuse as follows:
•
Remove all 120VAC power to the boiler. Check
that the unit is not powered from multiple sources.
•
Remove the front cover.
•
The 120VAC fuse is accessible by removing the
spring-loaded knurled knob of its holder. Push the
knob toward the panel and twist approximately 1/4
turn counter-clockwise.
•
To 24VAC fuse is located inside the control panel.
Disconnect the spark cable from the burner door,
loosen the two #8 hex-head sheet metal screws
securing the cover, slide out to remove and
disconnect the spark cable from the control. The
auto blade type fuse is installed in an "inline" style
fuse holder near the transformer.
•
Inspect fuses and replace if necessary.
•
Feed spark cable through the panel cover and secure
in place. Replace front cover. Restore power to the
boiler and confirm proper operation.

PROBLEM
POSSIBLE CAUSE
CORRECTIVE ACTION
Heat demand satisfied; no call for
heat
No action needed. Check operation by turning
thermostat up or jumping heat call (Thermostat to
R), or by turning DHW aquastat up or jumping
DHW call (DHW to Sensor COM).
Boiler outlet temperature is in range
Compare outlet temperature to Central Heat
(Thermostat) and DHW setpoints. Be sure to
factor in the outdoor reset curve – temporarily
disconnect the outdoor sensor to test – adjust
outdoor reset settings if necessary.
Hold or Delay
Burner not operating
Lockout
Check Operating Mode Icons for Hold or
Lockout. Obtain Hold or Lockout code number
from the Diagnostic Mode by pressing and
holding the “Next” button for 3 seconds.
Lockout 9 – Flame bias out of
range
4-20mA input being overdriven.
If using 4-20mA input, check to ensure current is
not greater than 21mA.
Hold 27 – Flame rod shorted
to ground detected
A flame circuit shorted to ground
may show up as a flame circuit
timeout. Zero-Ohm shorts can
display as Hold 27.
Check to ensure condensate drain is not blocked.
Check to ensure no voltage applied to R &
Thermostat terminals. If using 4-20mA input,
check to ensure current is not greater than 21mA.
Hold 61 – Anti short-cycle
Anti short-cycle timer is preventing
short-cycling.
Normal during small loads, delay is adjustable via
the Setup mode in the display.
Hold 62 – Fan speed not
proved
- Blower problem
- Faulty controller
If blower is off:
(1) Check for 120VAC power
supply to blower, correct wiring if necessary. (2)
Remove the low voltage cable from blower, if
blower remains off – replace blower If blower
turns on check VDC signal between black and
green wires, if between 12 and 16VDC – replace
blower, if not – replace controller.
If blower is on:
(1) Check low voltage cable from
blower to control. (2) Replace blower. (3)
Replace controller.
