Introduction Foreword

This User Manual describes the Flexface E Control System for FSS. 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 air conditioning units, depending on the Eprom Program (Eprom explanation see: Chapter 2.2,Eprom).

In the following sections, the hardware and later, the software (firmware) are explained in detail.

Hardware

2.1

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 unit.

The Flexface E is installed in the electrical panel.

NB: To access / set timer & some other functions, a Flexmatic E is required.

2.1.1

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

2.1.2

Networking between Units

2.1.2.1 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, Chapter 2.11).

Eprom / Flash memory

The eprom / flash is the device which stores the program the Flexface or Flexmatic E has to work with. It 2 doesn’t store any user-settings - this is done by the device itself (in the RAM and the E Prom). The version name and the number are printed on the eprom / flash label.

The following eproms / flashes are currently used for FSS units (the xxx is a placeholder for the actual version): HVM 1.00.xxx .........................................................................................................................................

Eprom 2 MBit, ....................................................................................................for Flexface E 24V AC. HVE 1.00.xxx Flash, 4 MBit, for Flexmatic E.

Figure 4 - Eprom 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 Figure 1 in Chapter “Flexface Evolution” for Flexface, and to Figure 13 in Chapter “Flexmatic Evolution Rear View, Jumpers and Eprom Position” for Flexmatic. Compare the mark on the eprom with the direction in the drawing.

2.3

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).

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 Chapter 2.11, Spare Parts List.

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.

Measuring Element Cable

Figure 7 – PTC Sensor

2.5

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.

I-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, see Chapter 2.1.1 on page 3 for the position).

2.7

Flexmatic E

Flexmatic E is a microprocessor-based electronic device, which makes it possible to control the functions of one or more Flexface devices. Flexmatic E offers numerous advantages in programming the units as well as optimising their operation. See Chapter 3, Software.

2.7.1

Flexmatic E direct Connection to Flexface

Flexmatic E can be fixed on the front panel of the unit. Connect the FLEXBUS cable as shown in Figure 11:

Figure 11 – Direct connection between Flexface and Flexmatic E

2.7.2

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 done from any place – 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 2.8.2, PSM Connection).

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. Input 24VAC / 24VDC+ 24VAC / DC GND not used

Figure 14 – PSM Module

Output Do not use

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 to Flexmatic six wire, screened Flexbus cable; the screen needs to be earthed in both terminals. When the system consists of more than one 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).

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 FSS supplier. Before connecting the cables to the Flexface, check with a cable-tester (see Spare Parts List, Chapter 2.11).

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 Figure 19.

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.

3.1.1.1

Meaning of the Symbols in the Main Window Return Air Temperature, composed according the “Sensor Priority” settings. The priority percentage of the sensors (return air sensor, 2 additional room and TU temperatures) may be set as required. The small number above the read value indicates the derived zone setpoint (read only). This setpoint (=actual zone setpoint) is the calculated average from all xtu’s which are not set as “ignored”. The control opens / closes the valve(s) according this value compared with the return air temperature reading.

Return Air Humidity. The value is read from the 2 additional room sensors (Humitemp) composed according the “Sensor Priority” settings.

The small number above the read value indicates the actual humidity setpoint (read only). If the humidity compensation is enabled, the actual humidity setpoint is recalculated according to the temperature deviation: every 1°C of temperature deviation from the humidity setpoint is modified by 3%rH. It will be increased by this number if the return air temperature is lower than the actual setpoint and will be decreased by this number if the return air temperature is higher than the actual setpoint.

Supply Air Temperature. The small number above the read value indicates the derived setpoint (read only). The supply setpoint is calculated from the deviation of the return air temperature from its setpoint, multiplied by the supply compensation factor. ...................................................................This graph shows the fanspeed of the CAM-C/CAM-V unit.
