The Edstrom Controller permits control of up to four electric solenoid valves activated in sequence. This helps reduce the amount of water required at one time by splitting a barn into multiple zones. The electronic Controller allows the user to program the thermostat and time settings. Its Smart Mode™ setting automatically adjusts the length of time between shower cycles (Interval Time) as the temperature changes.
Smart Mode was added after work with dairy cattle at Kansas State University showed a benefit to having at least three different shower time settings as temperatures increased. This feature is just as beneficial in the swine industry, as it reduces wasted water at lower temperatures while keeping ahead of heat stress as temperatures increase. The new Controller also has the ability to monitor up to four separate temperature sensors, so that multiple rooms can be cooled with a single Controller.
Programming of the Controller is easy to do. Time and temperature settings in both LO Range and HI Range are easily viewed and adjustable. The shower and interval times can be set anywhere within the range of 0 to 99 minutes. The actuation temperature can be set within 40°F to 99°F in either the LO or HI Range settings. You can also select the number of electric solenoid valves to be operated, as well as the number of temperature sensors that will be monitored. The Controller can be easily toggled to operate in either standard Two-Stage mode or in Smart Mode. Once the settings are entered, they are saved automatically, and will not be lost if the electrical power is interrupted.
