Cooling operation: how it works
Cooling systems reduce the air temperature by evaporating water into the air stream. The controller can
handle many cooling systems.
Cool cells or pads
A cool cell output operates a pump used to circulate water in an evaporative pad.
High pressure mister or fogger
A high pressure mister or fogger output operates a high pressure pump which creates a gentle mist by
forcing water through a set of nozzles.
Mister or Dripper
A dripper or mister output operates a valve that allows water into a drip nozzle line
Cooling operation
A cooling output starts operating in timer mode when the average temperature reaches the start tempera-
ture. The On time portion of the timer then increases as the temperature rises and reaches the Max On
Time value as the house/barn temperature reaches the Max Temperature. The following graph sums up
this situation:
