I have a older taco without the common. For each zone. I see a com and 24v fitting on the side but there is only one. Is that the common I need to connect to and if so can I connect two thermostats to that one fitting since I have 2 separate zones and pumps. Sorry it is hydronic baseboard heat. Thanks in advance for any help.

The common of the thermostat goes to common on the taco panel. You can use more than 1 common on terminal

I have an older 3 zone taco panel no c terminal. Can I use the common at the TT that goes to the thermostat splice at the thermostat and feed the c terminal for thermostat power. Since the tt terminals on the taco panel is always live with 24 volts

I have a older taco with no c wire but I ran two thermostats to mine. I ran a wire right from the top section that says c and 24v I ran a green wire from the c to the c on the thermostat then I ran red and white from each zone

Thanks for the quick reply. To clarify I have two wires at the thermostat since one of those wires is common can’t I just splice the common wire at the thermostat and use the splice for the c terminal at the thermostat and then the other part of the splice for the w terminal.
