My interest is to connect the Humidifier to the dedicated HUM terminals. I would like to know how to power the terminals on the circuit board.
I would be very glad, if someone could share some knowledge in powering the terminals.

Another issue I have is on the thermostat (White Rodgers Thermostat 1F78) when I move the fan switch to ON from Auto, I assume the fan should be continuously running, but that does not happen. Wiring connection from thermostat (white to W, red to RH, green to G, yellow to Y) going to furnace (white to W1, red to R, yellow to Y1, green to another green wire with a wire nut which is coming from the HRV), Help with this too would be appreciated.
Why is the fan not running? I would like to keep the fan running all the time if possible. (FYI HRV air is continuously on)

Thanks
