NRG Controller - How to Reset the Heater:

When an NRG Control displays "LOCK OUT", the heater has missed ignition or the flame signal during operation. 

A suspended warm air heater can be reset from the control, provided the lockout reset wiring between the heater and controller has been connected. 

To reset the heater, press RESET. The heater will reset after a countdown. 

If the lockout wiring is not connected, a lockout fault can still be identified and reset on the following heaters:

CTU, CTUC, ELU

  • RED and GREEN lights on the front of the heater become illuminated.
  • If enabled, the NRG control will display "LOCK OUT"
  • Reset by pressing the RESET button on the NRG control or the red rocker switch on the back of the heater (hold for 5 seconds) 

MGB, MOB, ELG, ELO

  • Indication light on the burner control box becomes illuminated.
  • If enabled, the NRG control will display "LOCK OUT"
  • Lockout reset is normally enabled for high-level installations.
  • Reset by pressing the RESET button the the NRG control or the illuminated button on the burner for floor-mounted installations. 

IMPORTANT NOTE:

Pressing the reset button on oil-fired and LPG-fired cabinet heater can build up unburnt fuel in the heat exchanger. If in doubt contact your usual gas safe engineer or the Combat Technical Help Team.
