NEW & Improved Watkins Hot Spring & Tiger River Heater Relay Board w/ Jumpers

Watkins Part Number: 74618

Replaces Watkins Part Number: 73355

This IQ2020 Heater Relay Board (PN 74618) recently replaced the older style (PN# 73355)

This IQ 2020 heater relay circuit board replaces all older style heater relay boards. This replacement is for all IQ 2020 controllers in all Hot Spring and Tiger River spas. It is the newest revision built even beefier to better endure areas where voltage spikes or frequent power outages occur. This heater circuit board also serves as a buffer to help protect the main board (motherboard / control board) especially in lightning prone areas. The part comes from the factory wired for a 230 Volt spa. JUMPERS ARE INCLUDED with detailed instructions for setting the unit for a 115 Volt spa.

Improvements in NEW Model 74618:

Compression wire connectors rather than spade connectors, provides a better connection.
Includes jumpers to set to a 115V spa (item pre-set for 230V)
New IQ2020 control board screws (2 Qty) (shorter screws as to not cause damage to internal components)
Easy to follow instructions for self-install. Tools required: Needle-Nose pliers and a Phillips-Head screwdriver

Symptoms of this part failing:
1) GFCI trips off when the heater comes on;
2) The heater board is charred on the backside -- look for black or white ash charred area. If present, your relay board is bad.
3) Spa is not heating.
