Replace Honeywell HumidiPRO Digital Humidity Control with nest?

[chris64]

Can you replace this standalone dehumidifier with a nest and control the dehumidifier outside of the HVAC system with the nest

Walmart Humidistat link 

It is wired to the C, R, U and U terminals. Any thoughts?

Hi @chris64,

Thank you for reaching out to the community. I understand you're looking to replace your Honeywell HumidiPro Digital Humidity control with a Nest Thermostat. I'm happy to share more information.

The wiring you've described, which uses U and U terminals, is for a specific accessory control that isn't compatible with a Nest's standard terminal layout. Attempting to force the connection could damage your equipment.

For your standalone dehumidifier, the best option is to either keep the existing controller or look for a smart humidistat specifically designed for your system. It's also preferable that you contact a technician who can help you find the best option.

Feel free to keep us posted if you have more questions.

Best regards,

Gabriela
