Connecting the AC IR Driver to the Ecobee 3

In the previous post we have created the IR Controller for the Samsung AC AR7000, so now it’s time to connect our Ecobee3 (modded for EU 220V Standard) to our Samsung AC.

Of course we need to add a new Relays to our electric panel and connect it to the Y1 pin in the ECOBEE plug panel.

Follow next schematic that is an improvement of first installation.

Connecting the Ecobee to the IR controller now is really simple!

Remove just the switch (keep the pull-down resistor) and connect instead the two pins AC_IR_DRIVER.

After that go to the Ecobee settings

Select Main Menu > Settings > Installation Settings > Equipment > Wiring

and configure manually to add Y1 and Y2 pin usage.

Test it by Main Menu > Settings > Installation Settings > Equipment > AC.

The thermostat will close the circuit every time he want to cool the apartment, closing the circuit is exactly like pushing the switch button on the IR Controller.

It will trigger a IR ON signal.

Once the thermostat want to stop, it will open the circuit (like releasing the button) and a IR OFF signal will be triggered.

(Of course you have to put your IR led in the AC direction or it will not work)

Let me know if it works also for you.

See you to the next post.
