73223 IQ 2020 Control Box, Hot Spring & Tiger River, 2001-2008 *NLA - Only Boards available: Board #77087 is used with Heater Relay board 74618.
Factory replacement IQ 2020 control box (main circuit board enclosed in a protective casing) for the Hot Spring 2005-2006 Accolade, 2001-2008 Grandee, Jetsetter, Prodigy, Sovereign and Vanguard, 2004-2008 Envoy and Vista, 2003 Sovereign Limited Edition (ILE), and 2001-2003 Landmark spa models. Also the 2001-2008 Tiger River Bengal, Caspian, Sumatran and the 2001-2004 Siberian spa models. Note: This IQ 20 20 circuit board (motherboard) is much safer, both in shipping and installation, for the manufacturer to enclose it in the $8 plastic box as a one piece replacement component.
Tech Tip: This new style IQ 2020 control box does not have thermistor ports on the side of the box. The control thermistor and hi-limit thermistor connect directly onto the IQ 2020 motherboard. If your current IQ 2020 control box has thermistor ports, then you will need one 39530 and one 39525 in addition to this controller replacement. These can be selected below in the drop down menu box.

Verify your thermistors are connected directly to the board, if they connect to the outside of the box you will need to replace the sensors as well.
