Tjernlund SS1 SideShot with UC1 Universal Control (Version X.06) 8504102 Rev D 07/05 User Manual

ELECTRICAL WIRING
All wiring from the SS1 to the appliance must be appropriate Class 1 wiring as follows: installed in rigid metal conduit, intermediate
metal conduit, rigid non-metallic conduit, electrical metallic tubing, Type MI Cable, Type MC Cable, or be otherwise suitably protected
from physical damage.
SS1 SEQUENCE OF OPERATION WITH INTEGRAL UC1 UNIVERSAL CONTROL AND 24 VAC
OR 115 VAC HEATER CONTROL CIRCUIT:
Control signal from thermostat, aquastat or primary control is intercepted and routed to terminal “1” on UC1 terminal strip. When
terminal “1” is energized with either 24 VAC or 115 VAC, the Venter motor is energized. After draft is established, the Fan Proving
Switch closes within 5 to 10 seconds energizing terminal “4”, which completes the circuit allowing burner to fire. NOTE: If a
Venter pre-purge is selected, the burner will not fire until the pre-purge time is finished. The Venter will continue to run after the
burner has finished firing for the set post-purge time cycle. The UC1 is set for a 2 minute post-purge time period from the factory.
See “Pre / Post-Purge Settings” on page 5 for details.
The "1" input terminal on the SideShot can accept either a 24 VAC or 115 VAC control signal. IMPORTANT: The RED volt-
age jumper must be positioned based on appliance interlock voltage 24V or 115V. If using the “DRY” contact activation method,
use terminals A & B on UC1 control and position the RED voltage jumper tab in the “DRY” position. IMPORTANT:
Only one interlock method (i.e. 24V, 115V or “Dry”) can be used with the UC1. Multiple appliance interlocks require the use of
our MAC-Series multiple appliance controls.
The steps listed under each diagram are intended as a supplement to the diagram. Wiring colors or designations may vary by
manufacturer. If you are unable to wire the SS1 as outlined in these instructions, call Tjernlund’s Customer Service Department
toll free at 1-800-255-4208 for assistance.
IMPORTANT: If the call for heat interlock signal or 115 VAC power is removed, the UC1 board will reset and any fault, if present,
will be stored in memory instead of displayed. See page 5, “Checking Memory for Last Fault Code”.

(THE SS1 MOTOR, LIMIT & PROVER ARE ALL FACTORY PREWIRED)
IMPORTANT: MORE THAN ONE INTERLOCK METHOD MAY BE APPLICABLE
In many cases it is easier to interlock with the thermostat/aquastat portion of the heater control circuit vs. the primary
control portion of the heater control circuit. Review all of the wiring diagram options prior to choosing the best method.
