Touch Screen Control
Touch Screen Control
|
The Touch Screen Controller is an advanced
central controller, which is available in various different
formats. It is available in four formats, to control
sixty-four or five hundred and twelve indoor units, each of
which are available with or without the billing function.
The Touch Screen allows full unit control of all connected
indoor units and is capable of giving full fault and
operating information. The controller has the ability to
schedule on/off times for each individual indoor unit.
The Touch Screen is compatible with all SMMS/SHRM
systems DI and SDI systems may also be added, but network
adapters are required.

Application
The Touch Screen would be used in an application where multiple
unit control is required from one location. The Touch Screen can
be combined with other components to provide energy monitoring
or a common fault input/output signal, which could be used for a
fire alarm shutdown or similar facility. If the billing function
is used a PC running Excel is required.

Connections
The Touch Screen connects to an RS485 Network,
which links the screen to the Relay Interfaces. The Relay
Interfaces are then connected to the Air Conditioning Network
via the U3 & U4 connection. The RS485 Network also connects to
the power meter and digital input/out interfaces. If the energy
monitoring facility is being used a separate PC will be required
to run the energy monitoring software.
This PC will require Microsoft
Excel and will need to be connected to the Touch Screen via a
network connection. The Touch Screen requires a 240V 3A mains
power supply

Additional Components
TCS Net Relay Interface BMS-IFLSV2E2
The Relay Interface connects to
the Touch Screen Controller via the RS485 Network using
connections A & B. The air conditioning network connects to
terminals U1 & U2 (U3 & U4 at the outdoor unit) and a maximum of
64 Indoor units may be served. The relay interface requires a
240V 3 A mains power supply.
Energy Monitoring Relay Interface
BMS-IFWH4E2
The energy monitoring Relay
Interface connects to the RS485 Network and provides a means of
interface to the pulse power meters. Up to eight power meters
can be connected to each Relay Interface.
Digital Input Output Relay
Interface BMS-IFDD02E2
The D/I module connects to the
RS485 network and provides 8 inputs and 4 outputs, which could
be used to interface a fire alarm system or a room occupancy
sensor. The D/I module output could be used as a means of remote
fault indication to another system.

Software
Site-specific software is written for the Touch
Screen, which gives specific names and locations for easy
end-user operation. The software also configures the D/I module
and the Energy Monitoring Interfaces.
Energy monitoring software is
installed on a separate PC. The software being Excel based and
using Macros to produce the reports for each Tenant.

Limitations
The total length of the U1/U2 network for each relay interface
is as follows
1.5mm2 Screened up to 1000m
2.5mm2 Screened up to 2000m
The total length of the RS485 Network A/B
1.5mm2 Screened up to 500m
