Upgrade your Legacy Control:

EnviroSTEP

Whats the difference?

Wadsworth designs and builds two types of environmental controllers: staged and integrated. Staged controls react to temperature changes by activating groups of heating and
cooling equipment as the temperature rises or falls. Integrated controllers set parameters for each piece of equipment, allowing it to respond independently and with greater efficiency.

The EnviroSTEP integrates all facets of the greenhouse environment by managing temperature, humidity, light level, CO2 and watering.

Many customers switch from staged to integrated controls as they improve and refine the greenhouse climate.

The EnviroSTEP control transforms the way your greenhouse functions. With better intelligence, more sophisticated control options and powerful accessories like the Weather Station, Alarm Manager, Lightning Protector and STEPsaver software, it gives you the support you need to be successful. The best news of all – it’s simple to install and easy to use.

Benefits and Comparisons

 Ramping

  • The EnviroSTEP has precise control, which allows a slow transition between temperature periods so no heat is wasted. This is known as ramping.
  • The STEP 50A transitions between the day and night periods using a photocell. The result can be a rapid and costly shift from the day to night period as the control works to reach cooler night temperatures by dumping the heated air from the daytime period.Three separate temperature setpoint periods
  • Day, Night and DIF setpoints offer three separate temperature periods.
  • Why separate heating and cooling setpoints? The EnviroSTEP offers a variable interval whenneither cooling nor heating equipment is running. It’s possible to set extremes such as a heating setpoint at 45o, to prevent frost, and cooling at 75o, offering, in this example, an acceptable span for the crop, when no heating and cooling costs are incurred.

    Design

    • The EnviroSTEP has a bright, easy-to-read screen with a home screen that displays current conditions. The STEP 50A has no screen.

    • You can use STEP Saver software to review crop settings and track your greenhouse remotely. Increased Performance

    • The STEP 50A operates heating and cooling equipment only.
    • The EnviroSTEP operates virtually any greenhouse equipment and offers the option of usingadditional sensors like a weather station or soil temperature probes.

      How do I switch the controls?

• The EnviroSTEP cabinet is identical in size to the STEP 50A, so they are easily exchanged. Generally, wiring remains in place. Simply disconnect the equipment wiring, trade out controls and reconnect. If the equipment being operated remains the same, the contactor panel will work with either control.

The EnviroSTEPs are easy to use and they have great longevity. The fact that the EnviroSTEP panels manage all the systems in each greenhouse has made controlling the climate easier. We are now able to achieve much tighter control in our greenhouses, which is very beneficial to our teaching and research programs. The great technical support makes using the system that much easier and gives me peace of mind.

“Being a research facility, we need to provide specific environments on a project basis. Our 50 EnviroSTEPs allow us to offer a precise climate tailored for each experiment, and that makes our researchers very happy.”

“I like the EnviroSTEP because of its ease of operation and flexibility. We use it to control a lot of different equipment including hot air furnaces, HAF fans, and multiple cooling units including, shutters, inflatable wall vents and fans. It allows us to control all of our equipment efficiently from a central controller. The EnviroSTEP keeps the greenhouse within our desired setpoint range and the control responds immediately to any adjustments I make.”

“We were asked to create a custom greenhouse for a private homeowner who insisted that all passive and mechanical temperature controls be fully automated. Fortunately, a colleague recommended the EnviroSTEP controller. It was great having the team at Wadsworth Controls working with us on our greenhouse project. From initial design consultations to the final programming, we were confident they would develop the best solution for our client. Wadsworth was able to tailor their product to the specific needs of the greenhouse owner, and their tech support team helped fine-tune the custom settings after installation. We are all very happy with the results and look forward to working with Wadsworth Controls in the future.”
