Recommended Troubleshooting
Check that the proper ID Card is securely connected. Perform a power and sys-
tem reset.
Perform a power and system reset. If the fault remains, replace the PIM.
N/A
Check for proper gas valve closure. Clean burner and electrodes.
Check the gas supply. Check transformer. Check igniters. Check wiring. Press
reset button on PIM/membrane switch. Recycle power.
Check HSI element. Replace as necessary.
Check the 24VAC input voltage – the voltage must be above 18.0VAC for proper
operation. Replace transformer as necessary.
N/A
Check for proper water flow. Check hi-limit setting and outlet sensor.
Check the VERSA IC Control for fault identification. Check sensor and wiring.
Check wiring at J8, pins 1 & 3 for loose or missing jumper.
Check system piping for leaks. Check water pressure switch (if equipped) and
connections. Check wiring on PIM at J1, pins 6 & 7 for loose or missing jumper.
Verify the tachometer signal and the connections at terminals J5 on the PIM.
Confirm power to boiler is at or above minimum required.
Check wiring on PIM at J1, pins 3 and 4 for loose or missing jumper.
Check pumps operation. Confirm proper water flow across heat exchanger (Delta
T).
Verify that the VERSA IC Control is connected and operating properly. Check the
cable between the PIM and the VERSA IC Control.
Check the VERSA IC for fault indication and troubleshooting information.
