Extending Your Propex HS-Series Heater Thermostat Wiring
Posted by Propex North America on Mar 26th 2025
If your installation requires a longer length of harness between your heater to your desired thermostat location, Propex North America has an 11-foot harness extension for plug and play functionality. This extension harness will work for the most recent iterations of the HS-2000, HS-2211 and HS-2800 heaters built after 2015.
Fitment Note: If your thermostat harness has an inline connector at the thermostat end like the photo below, the extension is compatible.
If this connector is blockish with dual rows like the photo below, it will not work with your unit.
