XP72 controls both the ventilation system and the sprinklers system of a dairy farm in an independent way.
Ventilation is controlled by 0-10V output when brushless or asincronous motors are operated by inverter; whereas the cooling control is performed by automatic timer of the water sprinklers (proportional to the temperature deviation), up to 6 water valve.
XP72 can work by 1 or 2 temperature probes (in installations with 2 water lines) and can be connected to a %RH probe. This allows XP72 to work by THI detection (temperature-humidity index) and also by wind meter control for protection from gusts of wind.
XP72 separately controls both the light periods commands and the off timings of the system.
