Gen 3 – Wiring Harness
Gen 3 Tankless Unit only.
Required if replacing a gray plastic flowmeter with a brass flowmeter.
To make the replacement, securely package the controller in a box that includes identifying information and send it to MistAway. We will make a modification to the hardware, upgrade the firmware, and return it to you, along with the new brass flow meter and wiring harness.
