Night cycle

This function needs a room temperature sensor and can only be active in unoccupied period and no optimum start or night purge is active.


When the room temperature drops below the value of parameter NIC-01, or exceeds the value of parameter NIC-02, the  night cycle function will be activated. The switching differential of the night cycle function is a fixed value of 2K. The night cycle function will provide a value of “2” on output "PlantMode", which starts the air handling unit to prevent that the room temperature will go out of the defined limits. See next figure.
