The heat downstairs is controlled by the Nest Thermostat (pictured above). It is located above the butcher block island. It is controlled by rotating it to raise or lower the heat. There are also other menus that can be navigated by a combination of rotating the thermostat and pressing it to “select”.
If the heat is currently heating – it will appear red like in the above picture.
If there is a leaf showing – it is in “eco” mode.
It goes to eco mode when it doesn’t detect people in the house for a long period of time. Just turn the dial to wake it up.
The heat upstairs is controlled by old-fashioned thermostats in each of the rooms. It is electric. Please remember to turn the upstairs thermostats off before closing up the house.
