This is for information only (use at your own risk) - We have seen the RHNF fault on this heater on an Arctic Spa and the following procedure has tested and sometimes rectified this fault.

  • On the PCB board - hold down the select ket for 5 seconds
  • You will see a LL followed by a number on the topside controller
  • Release the select key
  • Tap the change key until the number next to the LL on the topside is returned back to (i.e. scrolls back to this number)
  • Hit select key once
  • Hit the select key again
  • SC will appear for 1 min - this is the learning cycle
  • An X in a box will appear tap the key adjacent to it
  • The system should reset

If this fails then unfortunatley the heater has failed and needs to be replaced

2 Kw (Gecko code 0603-421003)

3.8Kw (Gecko code 0603-421005) - pick yours in the options, Yours may state 4kw but the 3.8kw is now the direct replacement, it is just badged up differently for the European market.

The design of its unique seamless enclosure and its cover gasket eliminates all risks of water infiltration. Filled with epoxy, its electronic board compartment is protected against the stress of water flow vibrations. It includes a built-in temperature probe and a new water flow detection feature that eliminates the need of a pressure switch.

No spares are available for this hot tub heater as it is a fully enclosed one piece unit.

In.therm controls multiple power levels on a single element extending its lifetime by heating at high power only when needed. With no moving parts and no adjustments, in.therm is hassle free and defines new levels of reliability.
