Upgrade your Legacy Control:

STEP Up

Upgrade Your Legacy Control to STEPUp

The STEP Up control transforms the way your greenhouse functions. With better intelligence, more sophisticated control options and powerful accessories like the Weather Guard, Alarm Manager, and STEP Up Compass, 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

Growers can save money and improve their crop by reducing the night time temperatures. The transition to the lower night time temperature is important, if not handled properly it can waste energy and increase expenses.

Ramping is the controlled transition between two temperature periods

  • The STEP Up 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 day to night because the control turns on cooling stages to drop to the lower night time temperature.The STEP Up offers improved setpoint control
  • The STEP Up’s three temperature setpoint periods: day, night and DIF offer better control.
  • You choose when to start each periods either based on sunrise and sunset or using clocktime. The STEP 50a control automatically switched from day to night based on the light level reading by the photo cell. Offering the grower no control over when the periods start.Temperature setpoint options:
  • The STEP 50a has only one temperature setting per time period. While this simplifies things for the end user it does not allow for a wide temperature span between heating and cooling events.
  • The STEP Up allows an energy saving option when neither cooling nor heating equipment is running. By offering a heating setpoint and a cooling setpoint it is possible to set extremes such as a heating setpoint at 50o, to prevent frost, and cooling at 75o, offering, in this example, an acceptable span for the crop, when no heating and cooling costsare incurred.Design
    • The STEP Up 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 Up Compass software to review crop settings and track your greenhouse remotely.

Our organization has benefited from choosing Wadsworth Controls. Their system has worked great, even in our non-traditional greenhouses and I’ve been able to operate the STEP Up even though my skill set has never been in mechanics or computers. Their service staff have also always been super helpful and friendly!

Benefits

  • Wadsworth programs your control to operate your heating and cooling equipment
  • Improves crop quality
  • 3 setpoint temperatures periods – day night and DIF
  • Reduced night temperature mimics nature
  • Use DIF to reduce stretch growth
  • Accurate temperature improves crop quality and consistency
  • Timed overrides allow you to fumigate
  • Reduces energy costs
  • Government approved energy saving device
  • Ramping allows for gentle transition between setpoint periods and saves fuel
  • Ability to lower the greenhouse temperature at night when 80% of the heating occurs, reducing energy consumption
  • Using one central temperature sensor prevents heating and cooling from running simultaneously
  • Solar-guarded, aspirated digital temperature sensor provides a more accurate temperature reading than traditional sensors
  • For every 1º of improved accuracy, you reduce energy consumption by 3% (compiled by the US Department of Energy)

Includes

  • Solar-guarded aspirated temperature sensor and 100’ of cable
  • Cable to connect STEP Up to contactor panel
