Concepts

The NuHeat Thermostat supports the following key concepts.

The target temperature is the temperature that the device attempts to achieve. The target temperature is either determined by the schedule programmed into the thermostat (auto mode) or may be overridden. When the target temperature is set by Home Assistant, the thermostat will hold this temperature until the schedule is resumed.

Using the thermostat in automations

To control a NuHeat thermostat from an automation or a script, use the climate actions and select your NuHeat climate entity as the target.

Available actions include:

To use these actions from an automation or a script:

  1. Go to Settings > Automations & scenes.
  2. Open an existing automation or script, or select Create automation > Create new automation.
  3. If you are setting up a new automation, add a trigger in the When section. Scripts do not need a trigger. They run when something else calls them.
  4. In the Then do section, select Add action.
  5. Select what you want to control. Under By target, select your NuHeat climate entity.
  6. From the actions shown for that target, select the thermostat action you want to use.
  7. Set the required fields.
  8. Select Save.

NuHeat thermostats do not have an off mode. To stop active heating, set the thermostat to its minimum temperature with the heat HVAC mode. This puts the thermostat in Permanent Hold, and it stops heating unless freeze protection is needed.
