Page 26: Boiler Extinguished Detection
7.8. Grate mode The GH22RA controller allows the heating regulation algorithm to be changed to ‘grate mode’, which does not support the feeder tray. It is usually used when the type of fuel is being changed, for example to wood or green waste paper. -
Page 27: Pump Only Mode
– GH22NA. 7.9. Pump only mode The GH22RA controller allows the heating regulation algorithm to be changed to ‘pump only’ mode. In this mode, neither the feeder nor the fan are supported.

User Instructions for GECO GH22RA controller ______________________________________________________________________________ 10. Alarms The controller has 11 alarms, including eight which will stop the controller for safety reasons and three that are warnings. For each alarm or notes, the number is displayed, along with text information describing the problem, and an audible alarm will sound. When multiple alarms occur, the details are displayed cyclically. - Page 34 User Instructions for GECO GH22RA controller ______________________________________________________________________________ Alarm 1 – Blown fuse/temperature limiter tripped This alarm occurs when the controller detects a zero signal from the power supply for two seconds. This may be caused by a blown fuse or tripped temperature limiter.
- Page 35 User Instructions for GECO GH22RA controller ______________________________________________________________________________ Alarm 3 - Damage to fuel feeder temperature sensor The user can force safe mode when the fuel feeder temperature sensor is damaged. Safe mode operation will continue until the controller is turned off, or the power is cut. After one of these events the controller returns to manual or automatic mode, determines that the sensor is faulty, and stores this as an alarm, so the operator must force safe mode again.
- Page 36 User Instructions for GECO GH22RA controller ______________________________________________________________________________ When parameter 'S49' = 1, note UW4 occurs, then the controller switches to safe mode and the boiler operates without the DHW/returning water temperature sensor.
