Versistep VersiSTEP Wadsworth’s VersiSTEP is a fully integrated computerized control. It provides 24 outputs for multi-zone control. If your application calls for more than just the basic VersiSTEP, add the optional expansion unit and get 16 more controlled outputs without the cost of a second computer. Also combine the VersiSTEP with the EnviroSTEP and microSTEP/SA controls on a single network that provides powerful yet economical control for large ranges. The VersiSTEP’s 24 relay outputs operate most any greenhouse equipment system. Heating, cooling, light level, CO2, irrigation and misting are all at your fingertips. Wadsworth custom programs each VersiSTEP before shipping it to you. This means you do not have to spend any time setting up your control once it is installed. Over time you will learn to further customize the control for each crop. We provide a video tape with a full training session, a detailed manual and optional on-site or internet based training to help you learn how to optimize your control. BENEFITS Improve Crops Improved crop quality Higher yield % Consistent crop quality Accurate Temp & RH § DIF reduces stretch without chemicals Multiple Sensor Sites allow for accurate control Control Light, CO2, irrigation, misting Reduce expenses Reduce energy consumption Lower labor costs Reduce chemical costs Increase longevity of equipment – Less wear and tear Reproduce top crops and improve your profits Assess your energy consumption through reviewing the equipment usage logs Knowledge is Power Data is logged in 15 minute increments and can be viewed in logs or graphs right on your control. Connect to STEPsaver for advanced reports and logging Accurate temperature and humidity data allows you to improve your crop quality Increase your ability for consistent crop quality Improve your yield percentage Assess your energy consumption through reviewing the equipment usage logs FEATURES This fully integrated computer provides 24 outputs for 1 to 8 zone control. If you need to expand your control, add the satellite unit for an additional 16 outputs. The VersiSTEP can be combined with the EnviroSTEP or other VersiSTEP controls on a single network that provides powerful yet economical control for large ranges. Control: 1-8 zone greenhouse environments. 3 setpoint periods: Day, Night and DIF o Setpoint periods based on time or automatic calculation of sunrise and sunset. Programmable ramp rates to gradually transition between setpoint periods. 24 relay outputs with manual override switches operate on/off, control reversing motors such as roof vents, energy curtains and mixing valves, modulation and pulse period modulation, irrigation, misting and HID lights Replaceable 10 amp DPDT relays. 4 analog outputs (0 to 10VDC) to control variable frequency drive, variable speed fans and modulating valves. Sensors: Includes highly accurate aspirated temperature and humidity sensor with 100′ of cable. A solar-shielded outdoor temperature and 25′ of cable Sensor inputs mount on terminal blocks for easy installation. 32 analog input channels o Connect light, CO2, RH, and temperature sensors. 8 digital detector channels o Sense precipitation, wind speed and wind direction. Records the status of all inputs and outputs in 15 minute increments. Connect to STEPsaver for advanced data logging and reporting. Alarm outputs: temperature, RH and power failure. Connect to Wadsworth’s Alarm Manager to receive calls on up to 4 phone or pager numbers. Fire response builds equipment response into each piece of equipment so it know how to respond in the event of a fire. Display Menu driven system makes operation easy. Largest graphical display in the industry: 8 lines, includes graphing functions. 4X4 keypad allows for easy programming. Fahrenheit or Centigrade selectable. Enclosure NEMA 4 cabinet – aluminum 32″ x 24″ x 5″ (813 x 610 x 127mm) with locking door, protects against sunlight and moisture. OPTIMIZE SYSTEM Optimize the power of your EnviroSTEP computer control with additional sensors. Your EnviroSTEP control includes a temperature and humidity sensor and an outdoor temperature sensor. Some growers add extra temperature and humidity sensors to average the readings in large zones. Adding sensors increases the power of your control. Optional Equipment STEPsaver Software connects your EnviroSTEP to a PC. This not only gives you remote access to your control but it also gives you more power. Weather Station can be added to your system at any time. One Weather Station can be connected to multiple STEP controls. The weather station monitors outdoor conditions and uses the information to enhance your EnviroSTEP’s control. Alarm Manager protects your crops by immediately notifying you when the conditions become dangerous and threaten your livelihood. Alarm Manager instantly starts calling the programmed phone numbers when the conditions reach your predefined level or if there is a power outage. CO2 sensor Wadsworth’s CO2 sensor uses non-dispersive infrared (NDIR) technology to measure CO2 concentration in the greenhouse air. Its microprocessor based electronics require less frequent recalibration than most CO2 units. Soil temperature probe For reading soil temperature, Wadsworth packages its proven semiconductor sensing element in a stainless steel tube that provides for fast, accurate readings while protecting the sensor. Hot water sensor Wadsworth packages its proven semiconductor temperature sensor technology in thermowells for insertion into hot water heating pipes, and in compact rapid response modules for mounting directly on the surface of heating pipes. Extended temperature range versions are available on special order if your application uses water warmer than 180ºF/80ºC. Light sensor (Pyranometer) Wadsworth uses silicon photovoltaic technology for light sensing. These sensors are accurate, durable, and economical. The sensors are protected in a plastic resin housing for indoor or outdoor use, and are cosine corrected to provide accurate readings at times of the day and year when the angle of the sun is low.
