It sounds like you have a good plan to me.
Be safe. After you feel comfortable that you have proven your wires, Turn off power to make your installation.

I would never try to install a fan center Hot.

You would be surprised at the amount of people that struggle to connect two wires with a wire nut.
I would verify that the connections are good.

Thanks for the advice! Will do.

final question from me.

Can i I connect both pumps to one switch/relay?

This way I can consolidate it to 1 stat and just place a ecobee sensor on the second floor?

I would not want to combine both zones.

You could install a second j-box next to that one and install the second fan center on it.
You could then install the second thermostat near this new fan center and install the wireless sensor on the first floor.

Adjustment to the temperature can be made via your cell phone or the thermostat.

Hey,

the wiring worked for the ecobee itís on and works with the relay switch.

the burner has two wires the one the receives the signal go turn on. That one is connected to the red on the relay.

the other one has 24vac coming out. Where does that get connected ?

To the other neutral wires?

Or

the other 120 live wires?

Here the picture- (black and blue) are line in from the stat- this is connected to the relay (RED -120vac out). the other end (white and black wires- 24vac out) . Do i connect this end to the BLACK wire coming out the relay. I'm afraid that with 120vac coming out the relay it will overpower this port. am i wrong?

Does the fan center make the pump energize which then brings on the boiler via an end switch?

Sorry- i'll be more descriptive.

Yes the fan brought on boiler first, which then turn on the pumps. The Fan end switch terminates here at the picture below. which is an genisys 7505 control. the cable(opposite of the switch ) coming out of the genisys is measure 24 vac. I am unsure if that end goes with the other neutrals or with the live wire.

I connected the wire coming out of the control (opposite of the switch) to all the neutral in my junction box. The burner started ti work and then stopped. Now the control is making a buzzing sound and not starting. Looks to me like this created a short or overheated the genysis control.

Im assuming it should have been connected to the live wires instead?

It sounds like we still need to trace wiring. I am not convinced that we have identified the 2 wires that went to the old stat.
It seems as if we have proven that we have not identified those 2 wires.
All the we need to do, after proving that we found them, is connect those 2 control wires together on are relay termimals 1 and 3.

I would expect the thermostat wires to energize the pump.

Did you prove this by isolating the wires on both ends then measuring for a closed and open circuit using an Ohm meter?
