I have an Aprilaire 600 series humidifier. I am installing the humidifier onto an Amana GMS80704B. The Amana unit has a wiring strip where the Thermostat wires terminate. The terminals are labeled Y (small blue wire & small white wire), W (small white wire), R (small red wire), G (small green wire), & C (small red wire). The Amana has a 12 pin connector also with slightly larger wires. The first row on the connector staring at the top from left to right is as follows - red wire, yellow wire, red wire, yellow wire. The second row down from left to right is as follows - Orange wire, Purple wire, Green wire, Purple wire. The bottom row of wires on this connector is as follows - Red wire, Blue wire, Blue wire, Brown wire. There are also severl white wires on a connector stip on the right side of the circuit board. One of the white wires goes to the exhaust fan. One of the white wires goes to the 120V neutral on the main switch supplying 120v to the unit, one of the white wires goes to a step down transformer on top of the circuit board, one of the white wires goes to what looks like the ignitor on the gas system, there is a much larger white wire that goes to the main blower on the Amana. The 600 series Aprilaire control has a terminal strip labeled as follows from left to right R, C, A, B, ODT, W, G, H, H, & Gf. I am not connecting anything to A or B terminals. I have already connected the ODT terminals. I habe already connected the two H terminals. I need clarifiaction on connecting the R, C, W, G, & Gf terminals.
