Question about Heating & Cooling
If you're wiring up 120 volts to the primary then you need to connect H1 and H3 together, then connect H2 and H4 together. Then connect one side of line (120 volts) to H1 and H3 and connect the other side of line (120 volts) to H2 and H4. Then for the 24 volts secondary X1 is one side of your 24 volts and X2 is the other side of your 24 volts.
For 240 volt primary connect H2 and H3 together, Then connect one side of your Primary (240 volts) to H1 and connect the other side of your primary (240 volts to H4. Then your Secondary 24 volts is still X1 and X2.
