I installed an Aprilaire 700 fan power humidifer to a Bryant 98MA furnace. However, nothing on the humidifier seems to work. I have installed the humidifer in the evolution thermostat and it thinks the humidifier is on and running.
Here is how I wired it up:
I connected the HUM and 24volt Common from the Bryant furnace board to 1 and 3 of a white rodgers 90-380 (relay). There is 24v present on the relay at 1&3 but nothing on 2&4 and 5&6.
I then connected 2 and 4 to the aprilaire brown wires on the humidifier.
Is this wired up correctly?
