Question About Aprilaire Thermostat 8555 and 8463
Can the Aprilaire 8643 be used to replace the 8555...

Can the Aprilaire 8643 be used to replace the 8555? The 8555 I have now has wires going to the RS+V, RS2 and RS1 terminals. The 8555 is obsolete and newer models no longer have these terminals. Can I wire those on the 8463
