HVAC Application

HVAC Application

The Eaton HVAC drive contains a preloaded application for
instant use and supports HVAC specific terminology and
functionality. In addition, the H-Max drive uses a patented
Active Energy Control algorithm. In addition to your drive
efficiency, the controller works to minimize losses in your
motor throughout the defined speed range delivering
industry-leading energy efficiency.

Specific Functions of Eaton HVAC Application

The Eaton HVAC application is an easy-to-use application for
not only basic pump and fan applications where only one
motor and one drive is needed, but also offers extensive
possibilities for PID control.

Features

●

Startup Wizard for extremely fast setup for basic pump or
fan applications

●

Mini-Wizards to ease the setup of applications

●

Hand/Off/Auto button for easy change between Hand
(keypad), OFF, and Auto (Remote control) place. The auto
control place is selectable by parameter (I/O or Fieldbus)

●

Control page for easy operation and monitoring of the
most essential values

●

Run interlock input (damper interlock). Drive will not start
before this input is activated

●

Different pre-heat modes used to avoid condensation
problems

●

Maximum output frequency 320 Hz

●

Real-time clock and timer functions available (optional
battery required). Possible to program three time channels
to achieve different functions on the drive (for example,
Start/Stop and Preset frequencies)

●

External PID-controller available. Can be used to control a
valve using the drive’s I/O, for example

●

Sleep mode function which automatically enables and
disables drive running with user defined levels to save
energy

●

Two-zone PID-controller (two different feedback signals;
minimum and maximum control)

●

Two setpoint sources for the PID-control. Selectable with
digital input

●

PID setpoint boost function

●

Feed forward function to improve the response to the
process changes

●

Process value supervision

●

Multi-pump control

●

Pressure loss compensation for compensating pressure
losses in the pipework, for example, when sensor is
incorrectly placed near the pump or fan

Startup Wizard

In the Startup Wizard, you will be prompted for essential
information needed by the drive so that it can start
controlling your process. In the Wizard, you will need the
following keypad buttons:

Left/Right arrows. Use these to easily move
between digits and decimals.

Up/Down arrows. Use these to move between
options in menu and to change value.
