Pellet stove

Versatile Thermostat's strengths

• Long cycles

  The cycle duration and the minimum on and off delays can be set to respect the stove's start-up time.

• Room sensor

  Temperature is measured where you live, not next to the stove, which would otherwise overheat the main room.

• Automatic stop and restart

  With a stove exposed as a climate, automatic stop and restart avoid leaving it idling when the room is at temperature.

• Presence

  The stove switches to Eco when the home is empty and restores Comfort before you return.

• Open windows

  The stove switches off when a window stays open.

• Failure detection

  If the temperature doesn't rise while the stove is supposed to be heating (empty hopper, ignition fault), Versatile Thermostat flags it.

Tutorial: a stove controlled by dry contact

Example: a pellet stove with a “room thermostat” input (dry contact), wired to a Zigbee relay module, with a temperature sensor in the living room.

1. 1

   Wire the dry contact

   Wire the stove's room thermostat input to a relay integrated in Home Assistant, following the stove's manual. Configure the stove to obey this contact.

2. 2

   Install Versatile Thermostat

   Install the integration from HACS, then restart Home Assistant.

   
3. 3

   Create the thermostat

   Add the Versatile Thermostat integration, choose “Thermostat over a switch”, name it “Stove” and select the temperature sensor and the outdoor sensor.

4. 4

   Add the relay

   In “Underlyings”, select the relay's switch entity.

5. 5

   Set a long cycle

   Choose a long cycle (30 to 60 minutes) and minimum on and off delays of several minutes, so a start-up always runs to completion.

6. 6

   Set the presets

   Define the Eco, Comfort, Boost and Frost protection temperatures, for example 18, 20, 21 and 10 °C.

7. 7

   Presence, windows and failure

   Link the presence sensor and the window opening sensors, then enable heating failure detection to be alerted if the stove doesn't start.
