Control functions
6.1.1
Control functions - options
Choose control functions - see Ch. A.
Options:
•
Supply air control: the temperature is controlled by the supply air sensor alone.
•
Outdoor temperature compensated supply air control: The temperature is controlled as a
function of the supply air with compensation for outdoor air temperature.
•
Cascaded room control: Cascade control of room temperature and supply air temperature to
achieve a constant, settable room temperature. The room controller output signal generates
the supply air controller’s setpoint value.
•
Cascaded exhaust air control: Cascade control of exhaust air temperature and supply air
temperature to achieve a constant, settable room temperature. The exhaust air controller
output signal generates the supply air controller’s setpoint value.
