How many Mats or Amps can I connect to the CommBox?

The CommBox-600 is equipped with four (4) 50Amp 3-Phase relay contactors. This means that at 2-phase, you can connect up to 200 Amps worth of power, but at 3-phase, you can connect 150A per contactor. The relays are rated for 120-600 volts so the CommBox can be wired for 208, 277 and 480 using 3-Phase.

Can one AirSense be used with two CommBoxes?

Out of the box, no. Each ‘box’ will need its own sensor to trigger. Click “Read More” for more details.

Programming your COMMBOX-600

The COMMBOX-600 is a “Plug and Play” controlled power distribution panel for frost protection, ice and snow melting projects. When receiving a signal from the sensor(s)m the contactors are activated, energizing your heating system. DIP switch settings determine how the zones activate. When programming your system, make sure DIP switch 1 is in the ON position. The program manual can be navigated by using the SELECT (+) to move forward or SELECT (-) to go back through settings.

What are the amperage capabilities of each Box at each voltage?

The amperage capacity of the Resibox is 120A and for the Commbox it is 230 Amps. The Resibox has (4) of the 30A/2-pole contactors rated 120-277V for a total of maximum 120A load capacity. Click “Read More” for details.
