4th gen thermostat

[bryanhudson]

I have an AprilAire E100 Dehumidifier connected to my HVAC / 4th Gen Thermostat.  I have my dehumidifier set to 50%.  In the mornings the humidy is aroud 56% but the thermostat does not call to turn on (only in the mornings).  After 10am the dehumidifier comes on.  Why doesn't the stat call for dehumidifier in the mornings?

Hello @bryanhudson 

Thanks for reaching out to our Nest Community. Im happy to help you with your dehumidifier readings and activation concerns.

Certainly this is not a normal patter on our Nest Learning Thermostat, For dehumidifiers, the Nest Learning Thermostat maintains a 6% humidity range of 1% above and 5% below the set humidity level. Example: If I have the Nest thermostat set to 40% humidity, the thermostat activates the dehumidifier when the humidity level reaches 41% and deactivates at 35% humidity; however, I will work to find a answer for this situation.

I would appreciate it if you could share with me more details about your HVAC and dehumidifier unit, like if it was installed in a single or two zone, or if is possible, a picture showing the wiring configuration for your unit.

With this more information, we can have a more clear answer for your situación.

Feel free to keep us posting. I'm here to help you.

Best Regards,

Douglas.

I have a AprilAire 100 dehumidifier controlled by my 4th Gen Google Stat.  My target humidity is 50%, but the stat never reaches 50%  (only 53%).  The stat/dehumidifier only runs for 10mins because the default setting with the stat (something I don't have access to) stops so that the coils don't freeze up.   This is an issue. I need the stat to run for 15 or 20 mins.

In these pictures cooling/dehumidifier stopped at 4am and its 9:41am.  This happens in the morning...
