No Scheduled Heating

[Brobinson]

Hi, we have recently installed a Learning Thermostat. It is instructing the boiler to provide hot water on a schedule no problem, and when we switch the Nest to manual it manages the boiler immediately.

However the problem comes when we look to manage the gas central heating on a schedule or through the Nest Dial. It simply won’t instruct the boiler to switch on and so constantly states the desired temperature ‘+2 hours’.

We really need this to work with two little kids and with the days getting colder.

Any help would be great.

Hi Brobinson, 

Yikes! I'm sorry to hear that your Nest Learning Thermostat is not instructing your boiler to come on. Let me take a look at this for you. A few questions: 

• Are you located in North America or Europe?
• What type of Nest Thermostat do you have?
• Does the thermostat screen indicate that it’s actively calling for heating?
• What type of furnace do you have? (gas, electric, etc.)
• When did heating last work?
• Did heating ever work with the Nest Thermostat? If not, did the heating work with the previous thermostat?
• 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?
• Did you select the correct fuel type?
• Do the LED lights blink on the HVAC control board? If yes, locate the light. 
• When was the last time you changed the furnace's air filter?
• Have you experienced extremely cold weather lately?
• Is this the first notable temperature drop of the year in the area?

I'll look forward to your response. 

Best,

Zoe
