ETO2 Snow and Ice Melting Controller

How do I wire my snowmelt system to the ETO2?

 

The ETO2 Controller has three 15 amp dry contacts and requires the installer to wire an external relay to connect the heaters/load to operate.

The ETO2 is an automatic electronic controller for ice and snow melting systems on outdoor areas and in gutters. The controller detects temperature and moisture. Therefore, both need to be present for the system to activate. Additionally, It’s suitable for controlling electric heating cables in 1 or 2 zones and features two-stage output control for efficiency.

The Relay-40 and the Relay-4×30 are relay options that Warmup provides, which you can pair with this controller.

Please refer to the installation manual for further wiring instructions.
