Heating system not responsive to temperature change

hi there

i recently installed the google nest thermostat.

While on the thermostat end it seems to be working fine, the heating system is not responding to the temperature change from the thermostat and it is constantly working on maximum.

Any clues how i can resolve that?

could it be that i need to change the system type?

Hi misterp, 

 

Yikes! I'm sorry to hear that your heating system is not responding to temperature changes from your recently installed Google Nest thermostat and is constantly running at maximum. Let's see what's going on. A few questions: 

 

  1. Are you located in North America or Europe?
  2. What type of Nest Thermostat do you have?
  3. Does the thermostat screen indicate that it’s actively calling for heating?
  4. What type of furnace do you have? (gas, electric, etc.)
  5. When did heating last work?
  6. Did heating ever work with the Nest Thermostat?
    If not: Did the heating work with the previous thermostat?
  7. Did you turn off the power to the HVAC system?
    • Did you recently turn off any breakers?
    • Have you recently experienced a brownout or blackout?
    • Is there a light switch near the heater that controls an outlet?
  8. Did you select the correct fuel type?
  9. Do the LED lights blink on the HVAC control board? If yes, locate the light.
  10. When was the last time you changed the furnace's air filter?
  11. Have you experienced extremely cold weather lately?
  12. Is this the first notable temperature drop of the year in the area?

 

Gather the power readouts of your Nest Thermostat's VIN, IIN, and PS-* under Settings > Equipment > Power Info for Nest Thermostat 2020 and Battery, VOC, VIN, and lIN under Settings > Technical Info > Power for Nest Learning Thermostat and Nest Thermostat E. Also, ensure that the wiring connections between your HVAC system and the Nest thermostat are correct and properly seated and if the situation still persists, try performing a reset on your Nest Thermostat to restore it to factory settings. This can help clear any potential software glitches or configuration issues. 

 

Keep us posted. We're happy to help.

 

Best,
