My old honeywell thermostat has broken. I'm going to replace it with a new T6360B. My broken thermostat (off the top of my head is the same model but without the led indicator) only has the terminals 1 & 3 wired to the control board (see attached picture).
Do I only need these two terminals or do I also need to wire in terminal 2? The current wiring has been made such that adding a third wire at the thermostat end is going to be a bit of a nightmare.
