Help Which Thremostat Do I Need.

I am sure there is a post on here with this information already so I apologize in advance for the duplicate question.

OK so my existing setting is a standard Air conditioner and oil fired boiler, hot water baseboard heat and standard off the shelf 5+2 programmable thermostat.

New Setup being delivered in couple weeks

1.York YHJF30S41S1 Heat Pump with York AVH36C3XH21C Air Handler with 10kw Electric Heat w/ Circuit Breaker installed (Air Handler is Communicating Control Capable, Not sure what that means).
2. Same Oil Fired Boiler for hot Water base board heat.

What I would like to accomplish is to use the heat pump for heat until the outdoor temperature makes it no longer efficient (Set outside temp?) then at that point use the hot water baseboard to heat the house.

Also if possible would like to have a certain preset temp that if something happened (e.g. boiler stops working, I run out of oil, etc) that it would go to an emergency heat mode and use the electric heat in the heat pump. (Manual switch to if wanted for some reason also?)

My schedule varys all the time so I like the convenience of a wifi enabled thermostat and like the looks and the tech of the touchscreens but that is not a must. It looks like the Honeywell line is pretty popular so I think that would be what I would prefer.

What thermostat and accessories for it do I need to meet my requirements?

I'd go with a Prestige IAQ and a wireless outdoor sensor.

I'm not sure that it would give you independent control of your heat strips though. It would control the strips as stage 3 heat.

What controls your hot water baseboard heating at this time?

Computerized controls that can do everything that you asked for are available.
The hardware is installed and the perimeters are programmed into them per your specs with a laptop. The company that I work for offers these controls but I am not the tech that installs or services them. We have a full time specialist for that.

there looks to be about 6 or 8 different models of the Prestige IAQ are there many differences between them? do they all need the redilink gateway to do the wifi thing?

When you say stage 3 heat, what do you mean? is that one that would come on after som much of a temp difference or a different set point?

The current set up a/c(being replaced with heat pump) and Oil fired hot water baseboard boiler is being controlled with standard off the shelf cheap thermostat form lowes or home depot , don't rember which one.

I think that there are 2 different Prestige IAQ thermostats available. The old model and the new model. The old model has a larger plastic border around the screen. The new model has more sensor inputs at the EIM and stores operation data at the stat. It looks better too.

There are many Honeywell Prestige IAQ and accessory combinations available and the new model is available in different colors.

This combination has the outdoor sensor and the new model IAQ...

Prestige® 2-Wire IAQ Kit - Amazon.com


Reading the manual would be a good idea before taking this route.

I think the Honeywell Prestige IAQ is the best stat on the market today. I use this thermostat. I install many of these thermostats but have never tried it with your application.

Again the computerized control option would give you all the benefits that you listed on your initial post. It might cost ten times as much as The Prestige IAQ...

Ok so I think I have it narrowed down to 2 selections:

1. Vision Pro 8000, EIM, RediLink, and either wired or wireless outdoor sensor

Models TM8321R1001, THM5421R1021, THM6000R1002 AND C7089U1006/C7089R1013

2.Redesigned Prestige IAQ Kit WITH Equipment Interface Module, Outdoor Air Sensor, 2 Duct Sensors
Redilink Gateway

Models: YTHX9421R5101 and THM6000R1002



Both Setups appear to do what I want it to (I think) Any advice on which one is a better thermostat; the Prestige or the vision Pro? Pros/Cons of each.

Any thoughts/recommendations/advice on the wired vs wireless for the outdoor sensor?

I wouldn't attempt it with the 8000 thermostat.

Based on the specifications you have you may want to contact the tech support with the manufacures to make sure you dont get the wrong unit.

I called Honeywell and the above setup should work they mentioned hooking up the oil boiler as y2 through an isolation relay and the electric heat in the heatpump as stage 3. and they also mentioned using the u2 and u3 contacts in the eim to do the same
