Tjernlund SS1C SideShot with UC1 Universal Control (Version X.02) 8504103 Rev 07/02 User Manual

ELECTRICAL WIRING
All wiring from the SS1C 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.
SS1C SEQUENCE OF OPERATION WITH INTEGRAL UC1 UNIVERSAL CONTROL:
Control signal from thermostat, aquastat, primary control or gas valve is intercepted and routed to terminal “1” on UC1 terminal
strip. When terminal “1” is energized with either 24 VAC or 120 VAC, the SS1C 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 SS1C will continue to run
after the burner has finished firing for the set post-purge time cycle. The SS1C 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 120 VAC control signal. IMPORTANT: The RED
jumper must be positioned based on appliance interlock voltage. For most furnace applications it may be easier to interlock with
the 24 VAC thermostat circuit. For most boiler applications it may be easiest to interlock with the 120 VAC aquastat or primary
control circuit to the burner motor. Choose the interlock method that best fits your application.
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 SS1C as outlined in these instructions, call Tjernlund’s Customer Service Department
toll free at 1-800-255-4208 for assistance.
IMPORTANT: To reset faults, verify fault by checking the LEDs and then remove call for heat.
