Zone control: Room cascade configuration example

Access 5.x

Ventilated premises is a shop-floor with a office inside it. Office zone requires additional heating and cooling to maintain comfort temperature.

Output of the office heater/cooler is being controlled by the zone controller in accordance to the room temperature.
