Flexface E / Flexmatic E 2015
Section One - General
1.0 General
This user manual describes the Flexface E control system for AET Flexible Space Under
Floor Air Conditioning (UFAC) system. It contains information concerning the architecture of
the control systems as well as the settings required to obtain the desired behaviour of the
unit.
The Flexface control system will effectively manage all the different functions of the CAM
range of units, depending on the Eprom program (Eprom explanation see: Chapter 2.3
Eprom). In the following sections, the hardware and later, the software (firmware) are
explained in detail.

Flexface E / Flexmatic E 2015
Section Two - Hardware
2.0 Flexface Evolution 24V AC
The Flexface Evolution is a microprocessor-based electronic card, which is able to manage
the devices and the sensors installed in the CAM. The Flexface E is installed in the electrical
panel of each CAM.
NB: To access / set timer & some other functions, a visual display Flexmatic E is required.
2.1 Flexface Evolution 24V AC
As the Flexface E is the “Heart” of the System which controls all functions of the unit, some
jumpers have to be set in order to tailor the control board.
Most of these jumpers are
already correctly set in the factory; only the jumper for the unit’s address (“A”) has to be set
in the field, during start-up of the unit.
Never add / remove jumpers when Flexface is under power

2.2 Networking between Units
2.2.1 How to connect the Flexfaces
Up to 16 units may be connected together via Flexbus, to be finally connected to one or
more Flexmatic E. The Flexmatic E offers easy access to all unit’s data, as well as other
features like graphic data records, timer settings etc.
Please note that a poor connection could cause serious problems to the
electronic devices (Flexface and Flexmatic); for this reason we strongly
recommend you to use only first quality products or to buy the cables directly
from your FSS supplier. Before connecting the cables to the Flexface, check
with a cable-tester, (see Spare Parts List, Section Two, 2.11).

Note: Length of Flexbus, connecting the Flexfaces, must not exceed 300 metres in total.
Length of Flexbus, connecting the Sensors and the TUx, must not exceed 300 metres in
total.
Note: Sensors must be connected first to the Flexface (max. distance 25 metres to the
Flexface), with TUx “after” the sensors, using “T” connectors.
All Bus-cables, going out from the CAM-C / CAM-V unit must be screened and earthed.
In total 24 Master TUx are addressable. Including Slave TUx, the number must not exceed
32 TUx in total, connected to one Flexface.

2.3 Eprom / Flash memory
The Eprom / flash is the device which stores the program the Flexface or Flexmatic E that
has to work with. It doesn’t store any user-settings - this is done by the device itself (in the
RAM and the Eprom). The version name and the number are printed on the Eprom / flash
label. The following Eproms / flashes are currently used for AET Flexible Space units (the
xxx is a placeholder for the actual version):

Figure 4 – Eprom (top) and Eprom Remover Tool
Power-off the device before mounting/dismounting the Eprom. Remove Eprom
only with a special tool; never use a screwdriver. For correct installation
direction, please refer to section 2.1 and Section 2.7.2 Flexmatic connection.

2.4 Humitemp and Humitemp Evolution
The Humitemp is a combined Temperature / Humidity Sensor. If connected, the Flexface will
use the values of the Humitemp for control according the sensor priority settings. It is
connected to the Flexface through Flexbus-Cable (max. length: 25 m). 2 sensors can be
connected to one Flexface (= to one air handling unit).

2.5 PTC Temperature Sensor
The PTC Sensors are used to read return air and supply air temperatures as well as outdoor
temperature. There are different types available: please refer to Spare Parts List, Section
Two, 2.11.
PTC Sensors are temperature-sensors, changing the resistance according to the
temperature (positive temperature coefficient). The connection is 2 poles. The max cable
length is 10 metres.

2.6 PTC Airflow Sensor / Differential pressure switch
The PTC Airflow Sensor measures airspeed in the same way as the one used for
Anemometers. There is an automated setup-procedure in the software to assist in setting-up.
The PTC Airflow is supplied with 24V, and gives back a signal of 0-10V DC, according the
airspeed measured. It must be connected to an analogue input. The connection is 3 poles.
The length of the cable for the sensor is 2 metres. The adjustment is done by software. Note:
depending on the unit’s configuration, a differential pressure switch could be an alternative.
It would need mechanical adjustment.

2.7 Board / TAM Module
The I-Board for CAM-C / CAM-V Units is the current transformer for the humidifier (cylinder
type). The I-Board consists of one current transformer-coil (one phase of the power supply
for the humidifier must be wired through the hole); and 1 output relay (to start humidifier, The
I-Board is simply plugged onto the Flexface. Please refer to Section 2.1, for the position.

2.7.1 Flexmatic E
Flexmatic E is a microprocessor-based electronic device, which makes it possible to
visualise and control the functions of one or more Flexface devices up to a maximum of 16.
Flexmatic E offers numerous advantages in programming the units as well as optimising their
operation; see Section 3.0.

shown in Figure 11.

2.7.3 How to connect more than one Flexmatic to the network
More than one Flexmatic E may be connected to a network. All Flexmatics will show the
same values (as they are reading out the data from the Flexfaces), changes of parameters
can be set from any Flexmatic – the last set of information sent to the Flexfaces through a
Flexmatic is valid. The only limitation (despite of the total Flexbus cable length of max. 300
metres) is the power supply of the Flexmatics: 1 Flexface can supply 1 only Flexmatic E. If
more Flexmatics are connected, PSM modules (see page 13, 2.8.1)

2.8 Power Supply Module for Flexmatic E
2.8.1 PSM Hardware
Flexmatic E may be supplied mounted in an independent electrical panel containing a power
supply module as well (PSM Power Supply Module) if the distance to the next Flexface is
more than 10 metres. The PSM Module itself needs a power of 24V AC / 30 VA.

2.8.2 PSM Connection
The connection between Flexmatic E and the PSM is carried out in the factory by means of
an eight wire Flexbus cable. The PSM should be connected to Flexface through a six wire,
screened Flexbus cable; the screen needs to be earthed in both terminals. When the system
consists of more than one CAM unit, a Flexmatic can be connected to any unit where
Flexface has a free Flexbus connector (usually either the first or the last one of the Flexface
chain).

2.9 Flexbus Cables and other Connection Cables
The connections between various Flexfaces, Flexmatic display and sensors are carried out
with cables having a different number of wires and different connectors. To see how these
cables have to be configured, see below. For the type of cable and connectors refer to the
Spare Parts List included in this manual.
Please note that a poor connection could cause serious problems to the
electronic devices (Flexface and Flexmatic); for this reason we strongly
recommend you to use only first quality products or to buy the cables directly
from your AET Flexible Space supplier. Before connecting the cables to the Flexface,
check with a cable-tester (see Spare Parts List, Section 2.11)

2.9.1 Addressing
When Flexfaces are connected by Flexbus cables, it is necessary to assign a different
address to each of them by means of a group of jumpers on the Flexface. The jumper
position is described in
The units must be addressed consecutively, starting from #1. The bus-cable
doesn’t necessarily need to go in order of the addresses; it could also be wired
1-5-4-2-3, for example.
