## Description

Honeywell TH4210D1005 Electronic Programmable Thermostat with Pullout Instructions : desertcart.in: Home & Kitchen

Review: This is a great functionally equivalent replacement for the Honeywell 8100 series heat pump thermostat. The terminals aren't exactly the same but I was able to figure out what went where by looking at the installation manuals for the old unit and the new one and lining up the functions.This unit is not billed as a homeowner installable (consumer grade) unit but I had no trouble installing it myself on my 2 stage heat, single stage cool heat pump. You'll need to know what kind of system you have, gas heat, electric heat etc but once you have the information you need, this is an easy install.
Review: We chose this thermostat to control a new installation of a heat pump coupled to a new LPG furnace, replacing my old oil furnace. It works great on the cooling cycle, and also on the heating cycle via the heat pump (haven't installed the LPG tank yet so that part hasn't been tested, but will no doubt work fine. Great to have central cooling, rather than fussing with my old window units. Just in time for the July heat wave here in Indiana. Installation was done by a certified HVAC technician, so I can't speak to the difficulty of installation, other than knowing the tech had no problems.

## Questions & Answers

**Q: Users manual for Th4210D1005**
A: How to cancel the program time/day/temp setting n run temp selected.

**Q: My current thermostat has both W2 and E wires. It an all electric house so i dont want emergancy heat to come on all the time. will this work?**
A: I have a Carrier year-old heat pump and this Honeywell thermostat and the auxiliary (electric in my case) heat WILL come on when the thermostat switch is in Heat position if the heat pump can not supply enough heat, so I usually increase the temperature setting only a degree at a time to slowly heat the house and avoid using the auxiliary (electric) heat source (in which case the thermostat displays "Heat on" but not "Aux Heat on" or "Em. Heat on").  The Em. Heat (Emergency Heat) position of the thermostat switch forces the auxiliary (electric) heat source to be used and shuts off the heat pump compressor (This might be the only recourse to heating up a cold house when the outside temperature is too low for the heat pump to do it or if the compressor won't run).  See the Honeywell manual at https://www.manualslib.com/products/Honeywell-Th4210d1005-10514.html

**Q: Is honeywell pro400 (th4210d100) a good replacement unit  for the honeywell t8011r? are there any compatibility issues?**
A: We love this thermostat and have had no issues with it!

**Q: I cannot read this unit very well.  Do you have to press something for it to light up so that it can be read???**
A: Just press any button and it will light up.
