Cheap Honeywell Prestige HD Thermostat Kit YTHX9321R5012

Customer Ratings:

The new Honeywell Prestige t-stat in the HD format is really a cool idea, I purchased this t-stat to replace the white rogers big blue, being certified to do A/C I thought this was going to be easy, some things to remember, 1. you need a 5 or more wire system on your A/C / Heat this thermostat takes a common wire to power it up, if you have only 4 wires then it will NOT work you will have to pull new wire from your control board to the t-stat, and forget about calling Honeywell customer service they are no help what so ever, after pulling new wire and doing the traditional hook up it was very easy to get this thermostat up and running it is very easy to program, I purchased the outside remote (wireless) to let me see what the weather outside was doing all in 1 place, this is a cool feature. I like the screen it is very well lit, it has very easy programs to operate through, like setting time, date cooling days ect The best feature is the clarity of the screen, at night in the absolute dark there is the thermostat all lit up easily read with the lights off, and you can adjust the screen brightness. There are a myriad of applications that can be chosen when programming, something I have never seen before in any programmable thermostat, I would suggest staying from installers mode, in that mode there are too many things you can mess up that are important that are pre set, I went in and only changes 1 thing, which was to let my A/C system had 2 stages, it comes set to 1 by the factory. All in all a great purchase if you can get over paying for cutting edge technology. I would highly recommended this thermostat!!!

Bought a similar model (HONEYWELL THX9321R5000) from another supplier about a year and a half ago. There are many things that I love about this thermostat. Easily read, great programming options, wireless remotes, and more. Recently the temperature readout has become erratic making the thermostat useless. Honeywell advertises a 5 yr warranty on this unit and provides a number to call for service. I called and was told that the unit can only be returned to the contractor that installed it. Even though the warranty specifically states that one can call the 800 number and have the unit replaced, Honeywell refuses to replace it. I informed them that I bought the thermostat on line and thus had no contractor. They are adamant about this item being a contractor item saying that only a certified contractor can install it. Garbage! I installed and programed this unit in 10 minutes. There is nothing different about installing this thermostat over a retail model. Just a marketing ploy! No where on the warranty does it state that the unit must be replaced by a contractor if defective. I have a useless $400 thermostat! My advise DO NOT BUY!!!!

Best Deals on Honeywell Prestige HD Thermostat Kit YTHX9321R5012

I have reviewed the Prestige HD Thermostat at its own page. This is a kit, combining the thermostat with the external temperature sensor. The setup for the temperature sensor was easy and the range is good. All of my thermostats all over the house get their updates with nary an issue.

One thing I found curious is that all thermostats have to be hooked up individually to the external sensor. So, every time you get a new thermostat, you have to retrieve the external unit, press its "pair" button and then you're good to go. Since it's a one-time thing, it's not a big deal. On the other hand, I'm surprised that Honeywell cannot design these thermostats to create their own local network, so that once the thermostat joins the network that it automatically gets the external temperature data. After all, they came up with their own proprietary network, right (redLINK).

To recap some of the points from my other review (full a full rundown, see the link above) keep a couple of things in mind:

1) Honeywell only supports the trades on this unit. You will get NO customer support as a end-user. You have to call a licensed installer.

2) This unit will not work as one would intend with a hydronic heating / AC cooling system, especially if you have a humidifier, unless you execute a workaround (see the other review for detailed instructions).

3) The unit setup functions are locked out by default, i.e. in order to access the installer menu, you have to look up the date code first.

4) The Honeywell universe is a walled garden. Yes, you can control this thing from an iPad with the right interface, etc. but you're locked into the Honeywell hardware to do so. Other advances thermostat systems are not as restrictive.

Honest reviews on Honeywell Prestige HD Thermostat Kit YTHX9321R5012

I bought a new home about 1.5 years ago with a requirement to have a furnace with zones or a dual upstairs / downstairs unit. We were sick of drastic cold/hot spots in our previous home. Even with a separate unit for our upstairs the furthest room where our youngest daughter sleeps was still ~4 degrees colder in the winter than the rest of the home. AC company came out and and confired air flow and insulation. I even crawled in the attic to confirm that there was ample insulation in the attic. The house is all blow-in insulation.

The AC company recommended a few products to help with but not fix our problem. This included 2 of prestige HD thermostats (one for upstairs and one for downstairs) along with the remote tempurature sensor and two whole house humidifiers.

I ended up purchasing two of the prestige thermostats (one from amazon) and installed myself after watching a few on-line tutorials. This saved me about $600 from what the AC installer wanted to charge me.

This thermostat has some additional controls for the fan cycle that my previous and very basic thermostat did not have. By cycling the fan more frequently we have been able to keep a more consistent tempurature in my daughters room at the end of the vent run. As the AC company stated it would help but not fully solve the problem. I will likely add the remote tempurature sensor so we can maintain temp based off the conditions in her room rather than ours.

Over all this product delivers a user friendly device with all the features you could ask for in a thermostat. I highly recommend so long as you can install yourself and save the inflated price of having an AC company mark-up and charge for instalation.
