How can I add an offset to the ZEN Thermostat? My temperature inside is different than what is being read.

You can add a positive or negative offset to the ZEN Thermostat in order to make the gap smaller.

To add an offset of the temperature as seen on the display:

1. Remove the device from the wall
2. Press the CONFIG button five times to enter the advanced menu screen.
3. Once you are in the advanced menu, navigate using the right arrow until you see T0 appear.
4. You can now adjust the offset up or down by the number of degrees you require.
5. Once you have selected this, press the center of the device to confirm your selection and your thermostat should blink to confirm your selection.
6. Return your thermostat to the wall and your adjustment will be saved to the device.
