Functions of the HVAC400 Drive
•
Wizards for startup, PID control, pump and fan cascade control, and fire mode to make commissioning easy.
•
The Loc Rem button for an easy change between the local and the remote control place. The remote control
place can be I/O or fieldbus. Using a parameter, you can select the remote control place.
•
Run interlock input (Damper interlock). Drive does not start before this input is activated.
•
A control page to operate and monitor of the most important values quickly.
•
Different pre-heat modes to prevent condensation problems.
•
A maximum output frequency of 320 Hz.
•
A real-time clock and timer functions (an optional battery is necessary). It is possible to program three time
channels and five intervals to get different functions on the drive.
•
Two PID controllers are available. You can use them, e.g., to control a valve with the I/O of the HVAC drive.
•
A sleep mode function that automatically enables and disables the operation of the drive to save energy.
•
A 2-zone PID controller with two different feedback signals: minimum and maximum control.
•
Two setpoint sources for the PID control. This is selected using a digital input.
•
A function for PID setpoint boost.
•
A feedforward function to make the response to the process changes better.
•
A process value supervision.
•
A pump / fan cascade control is available to control up to five motors.
•
A pressure loss compensation to compensate pressure losses in the pipework, e.g., when the sensor is
incorrectly placed near the pump or fan.
•
Single input control where the analog signal (0-10V or 4-20 mA) can also be used to start and stop the motor
without additional inputs.
