+The `generic_thermostat` climate platform is a thermostat implemented in Home Assistant. It uses a sensor and a switch connected to a heater under the hood. If the measured temperature is cooler then the target temperature, the heater will be turned on and turned off when required temperature is reached.
+
+```yaml
+# Example configuration.yaml entry
+climate:
+  platform: heat_control
+  name: Study
+  heater: switch.study_heater
+  target_sensor: sensor.study_temperature
+  min_temp: 15
+  max_temp: 21
+  target_temp: 15
+  min_cycle_duration:
+  # At least one of these must be specified:
+     days: 2
+     hours: 1
+     minutes: 10
+     seconds: 5
+     milliseconds: 20
+```
+
+Configuration variables:
+
+- **name** (*Required*): Name of thermostat
+- **heater** (*Required*: `entity_id` for heater switch, must be a toggle device.
+- **target_sensor** (*Required*): `entity_id` for a temperature sensor, target_sensor.state must be temperature.
+- **min_temp** (*Optional*): Set minimum set point available (default: 7)
+- **max_temp** (*Optional*): Set maximum set point available (default: 35)
+- **target_temp** (*Required*): Set intital target temperature. Failure to set this variable will result in target temperature being set to null on startup.
+- **ac_mode** (*Optional*): Set the switch specified in the *heater* option to be treated as a cooling device instead of a heating device.
+- **min_cycle_duration** (*Optional*): Set a minimum amount of time that the switch specified in the *heater* option must be in it's current state prior to being switched either off or on.
