For the life of me, I can't figure out why Honeywell has so many
different versions of the VisionPro, instead of one that you could set
up for different types of systems with dip switches and/or the
configuation setup menu. I have seen one that says it is for
gas/electic/heat pump, but there is no W2 terminal on it for the peat
pump, so there is no way to control the aux. heat. The White Rogers that
we usually use can be used on nearly any system-- gas, electric or heat
pump, single or two stage compressor, can be programmable or non, with
or w/o time delay for the compressor etc.
The OP probably just has a standard heat pump. Pretty much any heat pump
stat should work-- if it has an "Emergency heat' setting, it should have
a W2 terminal. Larry
