Hello,
How are you today I have a problem I have two thermostat in my house one for heating and one for cooling I would like to know how to connect it to one thermostat can you please help me or send me how to wire it please

Thank you
Tony

First you need to get the wires from both thermostats to one location, after that it's pretty simple, let me know if it's possible? If not, you may need to pull a new wire. What type of systems do you have?
