Heater Relay Board 77118
Watkins Heater Relay Board for Caldera, Hot Springs, and Tiger River Spas from 2009 to September 2012 using the IQ 2020 Control System. Used on spas from early 2009 through September 2012.
This is the current, updated circuit board and replaces the previous Circuit Board Part # 76071. Form, fit and function of the boards are identical, and thus completely interchangeable, however they are slightly different in appearance.
