1 General

The Multicalor MC-EE (modulating) air handling units are
compact high performance units. The units are fitted with ge­nerously sized heat exchangers featuring 6 rows. This guaran­tees high air temperatures even with moderate supply water
temperatures. As a result, the units are very well suited to be
used in conjunction with modern condensing boilers.

The fans of the MC units are installed downstream of the heat
exchangers. This ensures that the fan motors are always opti­mally cooled and the life span of the fan bearings is increased.
Special attention has been paid to the air tightness of the
units, so leak losses are minimal. The heat exchanger com­partments is insulated by means of a thick layer of air, so heat
losses are minimal. The apparatus is supplied ready to use. It
is sucient to install on site the hot water supply lines, the air
ducts and the electrical supply.

The MC-EE is fitted with an advanced controller based on an
Atmel RISC microcontroller and a high performance and high
eciency electronically controlled fan motor.

2 Technical data

In standard use the apparatus is used to distribute recycled air
to which not more than 25% outside air has been added, or to
distribute up to 100% outside air after heat reclaim. The unit is
factory supplied in this version.

In outside air version the unit is used to distribute air to which
more than 25% outside air is added. You can activate a special
program in the controller as to maintain a minimum air tem­perature (for best results an optional modulating 3-way valve
should be connnected). When this option is activated, a basic
frost-protection is activated to help protect the heat exchan­ger in case of frost danger. Nevertheless we suggest adding a
suitable anti-freeze solution to the heating circuit if the unit is
used as an outside air version.

The Multicalor MC units are available as upflow models. If you
need a downflow unit, you can turn simply around the unit
and flip the controller panel. Pay attention as to not drop the
panel – this may damage the flatcable connector.

2.1 General

The units comply to the machine directive 89/392/EEG, the
low voltage directive 73/23/EEG and the EMC directive
89/336/EEG.

The MC units are available in 3 sizes. Each unit is fitted with
an electronically commutated fan. You can easily change
the maximum airflow by reprogramming the unit via the
touscreen.

3 Operating and setting

3.1 General

The MC-EE is fitted with an advanced controller based on an
Atmel RISC microcontroller and a high performance and high
eciency electronically controlled fan motor.

A control panel has been installed on the appliance to change
the dierent settings of the appliance. The control panel is
equipped with a capacitive touch screen and a TFT colour
screen.

3.2 The control panel

A control panel has been installed on the appliance to change
the dierent settings of the appliance. The control panel is
equipped with a capacitive touch screen and a TFT colour
screen.

3.2.1 Basic screen

The following information is displayed on the screen as
standard.

3.2.2 Locking

If an error occurs that puts the safe operation of the appliance
at risk, the appliance will be locked. The cause for locking the
appliance is shown on the screen. The locking can be cancelled
by pressing the unlock button. If the error, however, has not
been resolved, the appliance will again be locked.

You must then contact your installer or the manufacturer for a
solution.
