Installing a york gas pack (maybe 7 or 8 years old... transferring it from one place to another) all is well but I'm slightly confused with it having two sets of thermostat wires with one having only r and w, I've been in this business about 10 months, I'm pretty good but still a rookie and this is the first time I've seen this... would like some help on this or maybe a simple schematic or diagram on this unit.. thanks in advance
