Tjernlund Products 950-8804 Control Board
The Tjernlund Products 950-8804 Control Board is the heavy-duty UC1 universal control replacement engineered specifically for Tjernlund power venters and draft inducers. As a direct upgrade for the legacy 950-8801 board, this 115VAC circuit board is designed to interface with almost any burner control circuit, providing critical safety interlocks for oil and gas-fired equipment. This power venter control board features adjustable pre-purge and post-purge settings via onboard dip switches, allowing technicians to fine-tune venting cycles and prevent draft-induced short cycling. The integrated diagnostic LED indicators provide immediate status feedback, simplifying troubleshooting for fan prover status and call-for-heat signals. Built for durability in high-demand mechanical rooms, the 950-8804 includes a 10-second prover switch delay to stabilize the system against wind gusts. Whether you are servicing an SS1, SS2, or HS-series unit, this draft inducer replacement board ensures the tight electrical tolerances required for reliable venting and appliance safety.
Key Benefits:- Universal Compatibility: Serves as the primary replacement UC1 control board for the full line of Tjernlund power venters and draft inducers.
- Enhanced Troubleshooting: Features five diagnostic LEDs (Amber, Green, Red) to pinpoint faults in the safety circuit or call signals instantly.
- Field Adjustable: Onboard dip switches allow for precise pre-purge and post-purge timing to match specific appliance requirements.
- Improved System Stability: Built-in 10-second delay for the fan prover switch helps avoid nuisance shutdowns caused by transient wind pressure.
- Simple Installation: Designed for rapid field replacement with compatible mounting hardware and clear terminal labeling for 115V or 24V calls.
Is the 950-8804 compatible with older power venters?
Yes, this universal control board is the standard replacement for all past year models of Tjernlund draft inducers and power venters, including the SS1, SS2, and HS series.
What do the flashing red LEDs on the board indicate?
The red status/fault indicator flashes specific codes to diagnose issues such as fan prover failures or burner circuit interruptions, allowing for faster field resolution without guesswork.
Can this board handle different thermostat voltages?
The board supports both 24VAC and 115VAC intercepted calls. Ensure the red voltage jumper is correctly positioned to match the call voltage of your specific application.
