Watkins iq 2020 heater relay board – part number 74618 (old part number is 73355). This iq 2020 heater relay circuit board replaces all older style heater relay boards (pn 73355). This newest revision is built 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 iq2020 control box board especially in lightning prone areas. The part comes from the factory with the jumpers for a 120 volt wired spa.
If your spa is wired 240 volt then you’ll need to follow the included instructions for inserting the jumpers prior to energizing the spa. 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. This upgraded circuit board replaces the first and second generation boards in the iq 2020 control board found in hot spring and tiger river spa models.
Upgraded iq 2020 heater relay board w/ jumpers & shortened screws for the front cover of the iq2020 control box. Symptoms this part has failed.
