How to Select the Ideal Greenhouse Line Voltage Thermostat

When choosing a thermostat for your greenhouse, consider these features:

  • Moisture and Dust-Tight Boxes: Ensure longevity and reliability.
  • Capillary Tube: Filled with liquid or gas, it expands to activate the switch, providing precise temperature control.

Best Practices for Thermostat Placement in Greenhouses

Proper installation is crucial for effective temperature control. Therefore, place the thermostat where it can accurately sense the air that your plants feel. For best results:

  • At Plant Height: Near the center of the greenhouse.
  • On End Walls or Sidewalls: Avoid placing directly above heat pipes or in the direct line of a heating duct outlet.
  • Shade the Thermostat: Keep it out of direct sunlight to ensure accurate readings.

Step-by-Step Guide to Setting Up Your Greenhouse Thermostat

Setting up your thermostat in the greenhouse is simple:

For Thermostats with Piggyback Plug

  1. First, plug the heater power cord into the thermostat plug.
  2. Then, adjust the thermostat dial to the desired temperature (e.g., 60°F). The Tempro thermostat will automatically shut off the heater once the temperature rises by 3°.

For Thermostats Without Piggyback Plug

  1. Initially, wire the thermostat directly to the heater.
  2. Next, adjust the thermostat dial to the desired temperature (e.g., 60°F). The Tempro thermostat will automatically shut off the heater once the temperature rises by 3°.

For additional information, see the complete instruction manual.

Ensuring Thermostat Accuracy in Your Greenhouse

Check your thermostat’s accuracy annually to maintain optimal performance. Dust and dirt can affect calibration. Therefore:

  1. First, clean the sensor with compressed air and wipe away any remaining dirt.
  2. Set the dial below room temperature for 10 minutes.
  3. Slowly raise the dial setting until it just makes contact.
  4. Finally, compare this setting with an accurate wall or digital thermometer. Note any discrepancies and have them adjusted by a service professional during the next furnace maintenance.
