If you already have one installed, this is a 1:1 install. just push in the pins to release the current wires, move the current wire to the same location on the new board and you can save yourself a lot of money.My HVAC company wanted to charge me over 800usd to install a new unit. They did not mention that the unit already in place, which they installed was still under warranty (5 year). When I mentioned the warranty they got quiet. In any case a re-install is easy, tape your receipt to the unit for a return.Sadly the manufacturer only talks with HVAC people when it comes to support. So..

By no means an hvac tech but its pretty easy to swap wire for wire when replacing the same model that died unexpectedly on us over night. Was quoted $550 from an hvac company and immediately looked to amazon. Took me maybe 10 mins to swap all the cables over and flip the power switch and bam it lit up and my ecobee thermostats automatically calibrated and now we're back up and running as this thing controls everything down to the fan function.

A/C Technician was going to charge me $1200, tried to tell me a bunch of bs of why i would not be able to perform this install on my own. I was able to install this in less than 30 mins and had my ac running with no issues. Thankfully i already had this very model installed so all i had to do was just release one wire at a time and insert onto the new one. For reference i have 0 ac experience or training

I bought this because we purchased a house that had a Honeywell MM2 Trol-A-Temp master/slave thermostat controller. We already owned two Nest thermostats that ridiculously does not work with this common setup. (Come on Nest, your thermostats should be able to talk with each other and co-ordinate.) You can bodge one Nest as the master thermostat with a Trol-A-Temp by pushing the heat change-over wire in to the W1 receptacle with the W wire so that the Nest will tell the MM2 to use heat and call for it at the same time (and do the same with the cool change-over wire and Y/Yellow). But then you have to leave the dumb slave thermostat in place and it can only call for heat or cool when the Nest is doing the same.The HZ311 was easy to install and includes a C connector for each thermostat to allow your smart thermostats like Nest to charge without having to call for heat or cool. It does this with a dedicated, required 24V tranformer (not included). This assumes you have enough wires running to your thermostat of course. (I have a Fast-Stat 3-wire to 5-wire on order since I cannot pull new cable to replace the 3 wire cable for zone 2.) Be aware that Nest's trick for sipping power by fast cycling the heat when it needs to charge does not play well with the HZ311. You must find a wire you can use for a C wire. Until my 3-to-5 wire system arrives, I have re-purposed the fan (G/green) wire since the thermostat usually does not need to control that on a modern (last couple of decades or so) system (and I assume the HZ311 would take care of that necessity any way). So I only have the ability to heat from my 2nd zone at the moment.tl;drWorks great with modern connected thermostats. Provides separate power for charging/running smart thermostats without robbing the HVAC or playing games. You must find a wire to use as a C/common wire.
