WCTW100H-A-B | W100 Cooling Tower Controller - 3 Powered - HW - 1x 4-20mA Out - Conductivity on Panel
W100 Series Water Treatment Controllers
The W100W series provide an economical and reliable way to keep your cooling tower, boiler, or condensate water treatment program under control.
Benefits:
- Large display with icon based programming makes setup easy
- Universal sensor input provides extraordinary flexibility; the same controller can be used with almost any type of sensor needed
- Multiple language support allows simple setup no matter where your business takes you
- The third control relay allows the controller to be used in more places than other entry level products
Complete flexibility in the function of each relay
- 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 percentage of elapsed time
- Biocide timer with pre-bleed and post-feed bleed lockout options
Optional analog (4-20 mA) output for recording, datalogging or connection to building energy management systems
