Tjernlund HS3,4,5 Series with UC1 Universal Control (Version X.02) 8504111 Rev 09/02 - Manual (Page 16)

Verify that LED #2 (Green) is lit.
Yes, LED #2 (Green) is lit: Verify that "call jumper" is connected from J1 to J2 on UC1 circuit board. With call for heat established,
verify that wiring is correct by measuring voltage between terminals 1 & 2 and 2 & 4 of UC1 terminal strip. Voltage should be the
same in both cases, if not rewire per appropriate diagram. NOTE: If using the “Dry Contact” interlock method, make sure that the
RED voltage selection jumper is installed on the dry contact tabs and High Limit has not tripped.
No, LED #2 (Green) is not lit: Remove call for heat and reestablish a call for heat to reset control. Within 1 minute of call for heat,
carefully jump a wire between P1 & P2 on UC1 control. LED #2 (Green) should light.
No, LED #2 (Green) does not light: Replace UC1 circuit board, part number 950-8801.
Yes, LED #2 (Green) lights up: Remove supply power to UC1. Remove Jumper from P1 & P2. The fan proving switch is not closing
or wiring connections are incorrect/broken. Disrupt call for heat. Remove leads from Fan Prover and initiate a call for heat. With
Venter running, verify that Venter performance is sufficient to close Fan Prover contacts by checking for continuity across switch.
No, continuity is not present: Visually inspect system for blockages. Confirm that maximum Venter BTU/hr. input and vent pipe
lengths are not exceeded or elbows are not installed directly on Venter discharge. IMPORTANT: Do not connect 5 foot section of
aluminum tubing directly to Venter housing. Sensing tube assembly provided with factory calibrated length must be used or Fan
Prover will not work properly. If everything checks out okay, replace fan prover.
Yes, continuity present: Recheck wiring.
