I want to wire in the following thermostat. a https://proax.ca/en/product/205417/RIT3110000thermostat
And and I am having a hard time understanding the wiring diagram .
I think I get that 5 is L and can be connected to your heater (3) or cooling (4). So pins 3,4 4,5 and 5 are just a single pole-pole double throw-throw switch? I would be able to connect 24V24 V to pin 5 and probe pins 3 and 4 to determine if the thermostat was above/below the set point? Or, or does the switch need power and is that incorrect?
Maybe instead pin 5 needs to be 120VAC120 VAC or 240VAC240 VAC depending on location, and then what would 1 and 2 be?
I'm missing something - any help would be greatly appreciated!
