Tongdy Greenhouse CO2 Controller
Part Number: ESTON-08
- CO2 Control for Greenhouse or Glasshouses
- Plug & Play – Install and Setup in Minutes
- Built-in Light Sensor Stops CO2 at Night
The Tongdy ESTON-08 Greenhouse Controller with Relay lets you simply and easily control carbon dioxide levels in a greenhouse or glasshouse. The ESTON-08 is extremely simply to use and can be installed in 3 steps:
- Mount the unit on your greenhouse wall
- Plug a CO2 regulator with 110-220VAC solenoid into the unit
- Plug the unit into a grounded 110-220VAC electrical outlet
With its LCD readout and easy-to use interface, you can customize your CO2 levels. By default, the regulator will be turned on whenever the CO2 level drops below 780ppm (double normal CO2 levels, perfect for most plants) and it is daylight. In addition, the Greenhouse controller can be calibrated using normal fresh air to save you money.
