Heat issue one/off switch 4 times in a hour

[Joadebos]

Hello.

i have a problem with my nest thermostat. 
I looks like the nest thermostat switch every 4 times off/on 1 a hour when the temperature has not reach the temperature. Can i change in the setting this switch moment.

The problem is now that our heat pump will do a restart because the thermal state do a switch off and on

Hi Joadebos, 

Uh-oh! If you are experiencing issues with your Nest Thermostat switching off and on repeatedly every hour before reaching the desired temperature, the temperature differential, also known as the "swing" or "deadband," sets the range for thermostat temperature fluctuations before activating the heating or cooling system. You can adjust this through the Nest app or the thermostat itself, but it may result in larger temperature fluctuations. And ensure your heat pump is functioning properly and that no underlying issues cause frequent restarts.

Let us know if that helps.

Best,

Zoe

first thank you for the reply.

I looking for the nest cycles per hour" setting instead of a deadband setting.

is not a temp issue, temp in house is 19c and the nest set temp is 20.5c.

I monitor the switch cable and it looks like the nest switch every 30min. To off and on.

(switch cable is the cable between the heatpump and nest)

so my question is there a setting that I can increase this time?

Hi there, 

The Nest Thermostat uses a learning algorithm to optimize energy efficiency and comfort by adjusting its cycling behavior based on temperature differentials and other factors. It does not have a manual "cycles per hour" setting, but instead adapts to your home's heating and cooling needs over time, considering factors like desired temperature, current temperature, and heating or cooling rate.

The Nest thermostat's cycling behavior, with the heat pump turning on and off every 30 minutes, can be attributed to several factors. The thermostat's built-in temperature differential, or deadband, determines when the system turns on or off. The deadband is typically around half a degree to a degree, and with a set temperature of 20.5°C and a current temperature of 19°C, the thermostat may be cycling to maintain the temperature within that range. The heat pump's performance and efficiency also influence its cycling behavior. If the heat pump is sized correctly and operating optimally, it should cycle less frequently. External factors like outdoor temperature, insulation levels, and airflow within the home can also affect the system's performance.

Keep us posted.

Thanks,

Zoe

How do i change the deadband on the unit.  I just now purchased and installed a Nest Thermostat and my furnace is short cycling.  

Please also email the response #

I have the same question. From what I found on the help center, the deadband is fixed at 0.7°F. Bummer. It would be extremely helpful if Google would let us adjust it. Hint, hint.

Hi folks,

I’m sorry for the late reply. I want to check if there might be anything else you needed on this or if you had any other questions. If there's more you need, just let us know.

Hi Zoe,

Is there a way to change the default 0.7° deadband a bit higher to keep the furnace from cyling on and off so much?

Thanks

Hi MCrash, 

The Nest Thermostat maintenance band is not adjustable. However, we appreciate your request for this additional feature, and please be assured that our product team is working non-stop with different partners to bring the best features to our Google Nest devices. So, please let our product team know about it by sending feedback.

Kind regards,
