How Do I Wire The Load to My ETO2?

The ETO2 Controller has 3 x 15 amp dry contacts and requires an external relay to connect the heaters/load to operate and switch loads/heating cables. The Relay-40 and the Relay-4×30 are relay options that Warmup provides, which can be paired with this controller. Please refer to the installation manual for further wiring instructions.
