Heater Relay Circuit Board 77119

Heater Relay Board with jumpers and shortened screws for the front cover for Caldera, Hot Spring, Tiger River and Lime Light hot tubs.

This Caldera, Hot Springs and Tiger River 77119 Heater Relay Circuit Board is the newest revision for the 2001-2008/Early 2009 IQ2020 Control Box. It's upgraded design provides a more efficient method of connecting the heater's power cord to this board. The black wire from the heater's power cord now connects into the H1 position on the large gray terminal block. The heater's white wire (neutral) connects onto its own separate gray terminal block. This will reduce stress on the relays and increase their lifespan due to better transfer of voltage. The ground wire connection remains the same.

Symptoms this part has failed:
  • No power going to the heater even though the red HTR ON L.E.D. light is lit inside the IQ2020 control box.
  • The heater board is charred on the front and/or the backside.

  • Watkins Manufacturing is the maker of Caldera, Hot Spring, Tiger River and Lime Light Spas. This Circuit Board is a genuine OEM Circuit Board replacement from Watkins Manufacturing.
  • This upgraded circuit board replaces the first and second and third generation boards in the IQ 2020 Control Box found in Caldera, Hot Spring and Tiger River spa models (replaces circuit board 74618).
  • This new board has a voltage jumper in the upper left corner that is factory set; although there is reference to instructions, No field action is required relative to this jumper at this time (it is for potential future use).
