The Infratech 30-4035 can regulate up to four output zones. A maximum of 40 amps continuous load and 9000 watts can be contained in each zone. Feel free to put any configuration of heaters in each zone, but make sure that they all have the same wattage.
When setting up the Infratech 30-4035 control, it is common to choose a convenient wall near the heater. The control is connected to the main control box with low voltage wiring. One twisted pair of wiring is needed for each remote controlled zone. To power the control, all that is needed is a 120V source and only 1 amp of power.
