Evaporative Cooling Basic Control
The wall mounted controller gives the following functions:
Off/On – turns the controller on and off
Cooling – Depressing the cooling button brings in the water circuit. If this is not depressed the cooler acts purely as an air mover providing ventilation
Fan Speed – Five speeds are selectable
Auto/Manual – this is used when the cooler is connected to a thermostat and/or humidistat. The fan speed and the cooling are automatically adjusted to meet a set temperature. The hotter the building the faster the fan speed.
