3015 and 3215 are the multi stage models in the builder series, controlling 2 heat and 2 cool on conventional plant. Programming can be set to 7 day, 5/1/1 or non-programmable, and the swing adjustments cover both stages separately so the second stage does not run when the first can hold the room. The housing is PP and the unit ships as a wired builder thermostat with one instruction sheet.
