Nest thermostat 4 gen auto eco and pre-cooling

[jolugo]

I upgraded my Gen 1 thermostat to a Gen 4.  I like to pre-cool my home to take advantage of the Time of use plan that the utility has and I turn it up all the way between 3-6p so the AC doesn't turn on at all.

I also use the Auto Eco feature when away to also save money.

Here is the issue.  If the thermostat is pre-cooling the house and I leave at that time, it goes into Auto Eco and then the AC turns on between 3-6pm.  Although its using the eco temperatures, it still runs several times during the "rush hour".

Im trying to find a way, to still use auto eco (when away) but keep the schedule for pre-cooling.  In other words, to ignore that someone is leaving during that time.

Any suggestions?

Thanks.

Hi @jolugo,

Thanks for reaching out to the Google Nest community. I'm sorry to hear that your Nest Learning Thermostat 4th gen is not working as expected with the Auto-Eco mode and is running during Rush Hours. No need to worry; I'm happy to assist you.

To help provide you with the correct information, I would like to ask you a few questions:

• When did you install the Nest Learning Thermostat 4th gen?
• What type of HVAC system do you have?
• Is this the first time you’re calling for cooling this year?
• Do you see a power error code on your thermostat?

Any additional details you can provide will be helpful.

Best regards,

Gabriela

I installed it about a month or so ago.

I have a heat pump split system

No, it's been on cooling for about two months

No error codes.  The system cools properly.

Thank you.

Hi @jolugo,

Thank you for your reply. I appreciate the information you provided me about your Nest Learning Thermostat (4th gen). I'm happy to continue assisting you.

I would like to know more information about the wiring in your Nest Learning Thermostat (4th gen). Can you please send me a picture showing the connection of your wires?

Also, you can try to reset the schedules in the Google Home app and create a new schedule.

Any additional details you can provide will be helpful.

Hi, I don't know what the wiring has to do with the away feature but I have Y1, G, OB and RH connected.
