Here is a video to provide you with a detailed understanding of the relay outputs.


We recommend to have these outputs control icecube Relays or Contactors to buffer the High Current Loads of your equipment.

Maximum Voltage and Run Current Thru 1400 Relay outputs recommended is 24VAC / 1Amp

You can wire your outputs as a wet contact installation, Dry, or Both.

Wet is to minimize the amount of Wires and Transformers (Leave Black Output Jumper use Master Common)

Dry uses a transformer for each piece of equipment. (Pull Black Output Jumper Use isolated Transformer)

Each Output also has a Hardware Interlock that prevents 2 adjacent outputs from turning on simultaneously.

Which is useful for Reversible Motors and 2 Speed Fans and

We recommend using Wired And Mechanical Interlocks for these types of applications and use the Red Jumpers as secondary protection

When you have finished your Hard Wire Installation, the Controller has manual toggle switches which allows you to manually override your devices, you can turn on, turn off,  your equipment to ensure that the Output is working ok, and when finished simply put toggle to AUTO, so the equipment follows automated programming
