30 second delay Honeywell.

[GeorgeMcDowell]

Hello, I have a Honeywell Thermostat.   My heating is electric.  (internal to the air handler). I've lived in the house for 12 years and when I moved in originally the previous owner had installed a Honeywell thermostat and he didn't do it correctly.  The heater kept blowing the trip switch in the air handler  It's been a while, but I seem to recall the Honeywell being set up for gas furnace(Honeywells default) and I can't remember exactly, but I do remember the thermostat did not give any time between switching over from heat to cold, which seemed to be the issue and I think I put a delay in there to stop this from happening, the fan runs for about 30 seconds to a minute, before switching over.  I do not see any delay mentioned in documentation of the Nest thermostat when the unit is switching over from heat to cold or vice versa.  Is this something that Nest thermostat accounts for?  My wires consist of R,o/b, y,g,c  and RC is jumpered to R.   The compatibility says it's compatible, but just a little concerned about the switching over from heat to cold part.

Hi GeorgeMcDowell,

Uh-oh! The Nest Thermostat is designed to seamlessly switch between heating and cooling modes, with a built-in delay to allow the HVAC system to adjust before switching modes. It detects your HVAC system and configures itself accordingly, requiring information about your specific setup, including heating and cooling equipment, to optimize its operation for your specific setup. This delay prevents potential issues from rapid mode changes.

The Nest Thermostat is compatible with electric heating systems and wires R, O/B, Y, G, and C. It can be configured to work with electric heating systems and control the reversing valve in heat pump systems. During installation, the thermostat guides you through setup and configuration steps, specifying your heating and cooling equipment. It adjusts accordingly for a smooth transition between heating and cooling modes.

Could you send us a photo of your Nest Thermostat wiring configuration so we can take a closer look? 

Keep us posted. 

Best,

Zoe

Thank you Zoe for your response.  It's nice to see the female workforce in this area of work.  I suspect you mean the Honeywell thermostat wiring?  I didn't want to install the Nest before I got a decent answer to this.  And definitely not right now, because it's cold/winter and I don't want to break my heater/tripswitch.   I would have to bozee up to the cat.  And he smells.  I'm only upgrading because I bought Google home voice.  And it would be nice to put my thermostat on the devices for control.  Below is a pic of my current thermostat wiring.  I'm not sure what looks to be bubblewrap is all about around the wires.   The part # of my Honeywell is TH811OU1003 if that helps.  The air handler was replaced about 7 years ago.  It's a Trane 4 ton R22 unit.  The condenser outside is American Standard.  I think the condenser is 20 years old.  Compressor was replaced by the previous owner at some point.  I don't believe there's any heat pump in it.   There's just a bunch of heating elements in the airhandler and a blower.
