MIST COOLING: Used to provide additional cooling for animals. Relay output to control misting unit(s). Mist cooling is assigned to the last cooling stage available automatically. If (2) heaters are used on Stages 6 and 7, mist cooling will be assigned to Stage 5. If heaters are used on Stage 7 only, then stage 6 will be assigned to mist cooling. If no heaters are used, then STAGE 7 will be assigned to Mist cooling. To use Mist cooling, press “ACTIVATE” icon. This will show which output has been assigned. During field wiring, it must be known how many heater stages will be used so that mist cooling stage assignment will be known prior to powering up controller.
