Greenhouse environmental controls

Wadsworth Step® Automation controls
The Wadsworth STEP Greenhouse Control Systems accurately and automatically control your retail or growing environment. You set up the program you want to use for your specific needs and the STEP Control System does the rest. Any kind of mechanical heating or cooling equipment can be controlled and their functions integrated into a total environment program.

Conveniently control any of this equipment:
• Exhaust fans • Motorized shutters • Automatic vent openers • Heater blower motors	• Gas solenoids • Hot water or steam valves • Turbolator jet fans • Cooling pad pumps

EnviroSTEP control system

Wadsworth’s EnviroSTEP can control any equipment in your greenhouse. It will control heating, cooling, humidity, shade curtains, lighting, irrigation and fog systems. Additionally, it has separate day and night and DIF climate settings which include ramping to allow gradual changes in conditions from one period to the next.

One Zone
Three setpoint periods: Day, Night & DIF
12 Relay outputs custom programmed for your greenhouse equipment
Two 0–10V Analog outputs (for proportional equipment)
Controls temperature: Heating & Cooling equipment – individual setpoint adjustment for each piece of equipment, lock-out options
Humidity, Fog, Misting, Irrigation—based on time, sun intensity, plant stress index, temperature
CO2—based on time, temperature, concentration level—can be tied to cooling setpoint, vent operation
HID lighting based on time, sun intensity
Energy Curtains—based on time, sun intensity, temperature, separate, heat, cooling & shade settings
