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
