1 - GENERAL DESCRIPTION
The "50FC" control is an electronic module with microprocessor
designed for the control and supervision of air-air units.
This control consist of a control board, sensors, a Graphic terminal,
and an User terminal (optional).
This system uses a RS485 field-bus to manage additional
components such as: c.pCOe expansion modules, SMALL board,
plug-fans, probes of temperature or relative humidity of the ambient
air, leak detectors, energy meters, etc.
This board also integrates two communication ports that allow
connection with a centralized technical management system such
as BOSS and BOSS mini. A BMS port for Modbus RTU protocol and
an Ethernet port for Modbus TCP/IP protocol.
A communication card (optional) can also be connected to the control
board for the following protocols: TCP/IP, modbus TCP/IP, SNMP
V1-2-3, FTP, HTTP, Ethernet BACnetTM, BACnetTM MSTP, Konnex

1 - GENERAL DESCRIPTION
1.9. Communication in a SHRD shared network
By default, the electronic control is configured for a stand-alone unit,
but it is also possible to include it in an SHRD shared network as
Master, Slave or Back-up.
The Mater/Slave network allows the exchange of data and
information between the units, and depending on the conditions of
the installation, it can share the reading of some probes installed on
the unit configured as “Master”, temperature setpoints, and operating
mode. The maximum number of units that can be integrated into a
Mater/Slave network is 15.
The Back-up network allows to configure one unit as a “Back-up”,
for activation in case of malfunction of the other unit. The maximum
number of units that can be integrated into a Back-up network is 2.
Communication between network units is via the Ethernet port of each
control board.

Functionality
Important: to use any of the following functionalities it is necessary
to configure in the “Selection software” one unit as Master and the
others as Slaves (including the backup unit).
The SHRD network allows to have the following functionalities
depending on the parametrized configuration:
Master/Slave:
It allows to share some of the probes installed in the Master unit:
ambient temperature or ambient temperature + humidity, outdoor
temperature, outdoor humidity and CO2air quality.
Extended Master/Slave:
It includes “Master/Slave” functionalities and the Master unit
provides ambient temperature setpoints to the other units.
Master/Slave with the same operating mode:
It includes the “Extended Master/Slave” functionalities and the
Master unit also provides the status (Cooling- Heating - Ventilation)
to the other units.
Back-up in case of alarm:
One of the two units is configured as a backup unit, for activation
in case of malfunction of the other one.
Extended Back-up:
It includes the “Back-up in case of alarm” functionalities and also,
the control manages the automatic switching between the two
units weekly, to compensate the operation times of both units.
Important: the “Back-up in case of alarm” function always prevails
over “Extended Back-up”, i.e. if one unit has to operate for a
specific week but a severe alarm appears, it will automatically
switch operation to the other unit.
Alarm levels are set to determine which of the two units should
operate (see Chapter 14. Alarms).
Note: In the case of installations with Back-up units, it is not
possible to share the probes, since both units must be fully
autonomous in their operation. If both units are connected to the
same supply duct network, it is imperative that the installation
consists of non-return dampers (installer responsibility).
For more detailed information refer to the manual of the "50FC"
control (No.10186).
For more detailed information refer to the manual of the "50FC"
control (No.10186).
1.10. Communication in a pLAN local network
This connection on a pLAN local network allows reducing the number
of Graphic terminals, since a single shared terminal can monitor all
units in the network.
The maximum number of units that can be configured on a Master/
Slave pLAN network is 15, and in case of Back-up units is 2.
The maximum number of units that can be connected on a pLAN
network is 15. As many Graphic terminals as units can be added to
the network. The terminal installed on the unit with address 1 will
be configured as shared and the rest as private.
Important: If the units are also to be included in a SHRD shared
network, the same addresses must be used on both networks
to avoid errors. Both, units and Graphic terminals, are shipped
configured from the factory.
Units configured as "Back-up" cannot be connected in a local
pLAN network, since the two units must be fully autonomous in
their operation.
Communication between the units of the pLAN network is carried
out using the fieldbus1 of each control board.

The control will compare the temperature reading of the ambient (or
return) air probe with the value set by the COOLING setpoint and
with the value of the control band.
The unit will stop when the ambient (or return) temperature drops
below the setpoint + one-half of the dead zone value.

Illustrative example:
- Summer setpoint = 26.0ºC
- Di󰀨erential band = 3.0ºC and Dead zone = 0ºC
- Unit without cold water coil.
• Units 2 compressors:
With the temperature below 26.0ºC, the compressors stop. If the
temperature starts to rise and exceeds 27.5ºC, compressor C1-1
starts. If it continues to rise and exceeds 29.0ºC, compressor C2-1
is also activated.
If the temperature drops below 27.5ºC compressor C2-1 stops. If it
continues to drop until reaching a value below 26.0ºC, compressor
C1-1 stops (the o󰀨and on command for the compressors will
depend on whether the rotation is activated or not).
• Units 4 compressors:
The control band is divided between 4 compressors.
As backup cooling, these units can incorporate a cold water coil
(V3V). For the regulation of the coil, the control has a proportional
or on/o󰀨output Y2 which controls the three-way valve.
For the input of the compressor stages, the control will use the
control band value, whilst for the water coil (optional), it will take
the di󰀨erential into account.
The input command for the previous chart can be modified using
parameters in order to give priority to the hot water coil.
Note: When the outdoor coil pressure of a circuit overcomes a
limit value (41,5 bar by default), one of the two compressors will
be stopped, thereby avoiding the stop of both compressors due to
the high pressure. This compressor will start working again if the
pressure drops below 36,5 bar.
7.2. HEATING operating mode (winter)
The control will compare the temperature reading of the ambient (or
return) air probe with the value set by the HEATING setpoint and
with the value of the control band.
As backup heating, these units can incorporate any of the following
components:
- a hot water coil (V3V).
- two stages of electrical heaters (R)
- a gas burner.
- a gas boiler.
An example of input command of the various stages is the one

Forced disconnection of stages
It is possible to disconnect compressor or electrical heater stages,
by using parameters or mechanically using the digital inputs of the
expansion card c.pCOe with address 8.
This is useful for reducing electric consumption in time bands when
the electric price rate is high or in those cases where the electricity
consumption or the section of the electrical outlet are limited.
For the regulation of the hot water coil, the control has a proportional
or on/o󰀨output Y2 which controls the three-way valve, and for the
regulation of the electrical heaters, there are two on/o󰀨outputs
NO6- NO7.
The previous configuration is typical for the options however the
control can also administer a proportional electrical heater stage in
the output Y2 and an on/o󰀨water coil in output NO6
For the input of the compressor stages, the control will use the
control band value, whilst for the input of heaters and of the water
coil (optionals), it will take the respective di󰀨erentials into account.
The input command for the previous chart can be modified using
parameters in order to:
- Give priority to the hot water coil (by default).
- Activate the electrical heater stages without activating the
compressor(s) for cases of compressor breakdown or blocking
due to a low outdoor temperature.
Important: if this blocking is enabled, half of the compressors will
be disconnected at an outdoor temperature of -11’5ºC, and all
other compressors with a temperature of -14.5ºC. The recovery
compressor (optional) is authorized to operate.
