Hi everybody,
I have an Aprilaire 600A, and just like the title says - it won't turn on. I have 24vAC at the 'R' and 'C' terminals in the controller. The water solenoid is hooked up to 'H' terminals. The outdoor temp sensor is hooked up to 'ODT.' And the unit is set up to use the call for heat from the t-stat to detect blower operation, so 'W/G' on the Aprilaire controller is hooked up to 'W' on the furnace board and 'Cf' on the controller is hooked up to Common on the furnace.
Does it sound like my connections are correct? It won't even light up in 'Test/Reset' mode. Any ideas? Thanks in advance!
