• Multiple language support with simple setup
• The third control relay allows controller to be used in more places than other entry level products
• Optional analog (4-20mA) output for recording, datalogging, proportional control or connection to building energy management systems
• Wall mount package for easy install
• On-screen graphing of sensor values and control output status

Complete flexibility in the function of each relay-

For Cooling Tower or Boiler Applications:

• Bleed on conductivity
• Bleed Time Proportional to makeup water volume 
• Boiler blowdown on conductivity using intermittent sampling
• Feed in proportion to bleed time
• Feed time proportional to makeup water volume
• Feed as a percent of elasped time
• Biocide timer with pre-bleed and post-feed bleed lockout options

For General Conductivity, pH, ORP, and Disinfection Applications:

• Time Proportional Control
• Pulse Proportional Control (when purchased with 4-20mA or pulse solid-state opto outputs)
• In-range or Out-of-range activation
• Probe wash timer
• Timer-based activation
• Activation basedupon the state of a contact closure
• Timed activation triggered by a Water Contractor or Paddlewheel flow meter's accumulated total flow
• Activate with other output
• Alarm
• PID Control (when purchased with 4-20mA or pulse solid-state opto outputs)
