Equipment – Thermostats – TS150W – Heating Issues
This article will guide you through troubleshooting when a customer is calling in to troubleshoot heating issues with a TS150W thermostat. This is for situations where there are true performance issues and not when the customer is requesting a temporary override to raise the heat set point lower than it is typically running.

Heating Issues

- Locate the TS150W Thermostat
- Check that the screen is illuminated.
- If there is no power to the screen, access the power issues article.
- Is there physical damage?
- If there is physical damage, contact GridPoint Support for more details.
- Check the thermostat’s mode and verify it is in either “heat” or “auto”.
- To check at the thermostat physically, check to see if the “heat” icon is illuminated.
- Check within GEM or GridPoint Intelligence.
- Check Heat Set Point.
- The heat will only run if the heat set point is higher than the zone temperature.
- If the heat set point is higher than the zone temperature and the thermostat will not run, contact GridPoint Support.
- If the heat set point is equal to or lower than the zone temperature, there do not appear to be heating issues. Align if they are requesting a temporary override or if they’re seeking to change the heat set point (and verify that they’re authorized to do so).
- If the thermostat is still not functioning as anticipated, contact GridPoint Support.
- The heat will only run if the heat set point is higher than the zone temperature.
