The C-440S Controller is used to regulate the showering and interval cycles in a dairy cow cooling system. It has output to control up to four 24VAC electric valves. The valves are activated in sequence to reduce water capacity demands on your system.

This easy-to-program controller can be set to operate either in Two-Stage Mode or Smart Mode. Two-Stage Mode provides traditional two-level cooling - a lower intensity cooling cycle operates when the temperature is above the low threshold. A higher intensity cooling cycle operates when the temperature is above the high threshold.

Smart Mode provides innovative, infinite-stage cooling. Interval time is automatically adjusted as the temperature changes. The interval time is the period of time when no showering occurs and the water is allowed to evaporate from the cows. As temperature increases, the interval time will decrease, thus giving animals more frequent shower cycles, to reduce heat stress. This provides exactly the right amount of cooling at any temperature while minimizing water usage.

The C-440S can monitor up to four separate temperature probes to allow accurate cooling in different zones. One temperature probe is pre-wired into the Controller at the factory. If additional probes are desired, they will need to be wired into the Controller on site.

Features and Benefits

  • Operates up to 4 electric solenoid valves/zones in sequence rather than all at once, to reduce water capacity demands on your system
  • Monitors  up  to  4  separate  temperature  probes  to  allow accurate cooling in different zones
  • Two-Stage Mode provides traditional two-level cooling – a lower intensity cooling cycle (LO Range) operates when the temperature  is  above  the  low  temperature  setting,  and  a higher intensity cooling cycle (HI Range) operates when the temperature is above the high temperature setting
  • Smart Mode provides innovative, infinite stage cooling – it varies the interval time in direct proportion to the tempera- ture difference as the temperature moves between LO Range and  HI  Range  actuation  temperature  settings,  providing exactly  the  right  amount  of  cooling  at  any  temperature while minimizing water usage
  • With Smart Mode, you program the system once – no need to make adjustments as the temperatures change during the season
  • Shower  time  for  each  electric  solenoid  valve/zone  can  be programmed independently – each valve/zone can have a different length shower cycle if desired
  • 24 Volt AC power output for safety and ease of installation
  • Super bright LED displays for viewing indoors or outdoors
  • User programmable – quick and easy to program
  • Easy and economical to install and operate – quick return on investment
  • Fully  compatible  with  previous  model  controllers  to  allow upgrades of existing systems
  • 2-Year Factory Warranty
