TW/.., PCW/.., XW/R/IQ Wireless Sensors and Receiver


The TW/.. wireless temperature sensors, PCW/.. wireless pulse counters, and XW/R/IQ wireless receiver provide a cost effective flexible wireless system for BMS temperature measurement and metering.

The TW/S space sensor is packaged in a standard wall mounting enclosure, whereas the TW/P HVAC equipment sensor pcb can be fitted into any of the IQ system HVAC equipment sensors (TB or TE- /O outside, /C clamp on, /I insertion). The PCW/.. pulse counters and XW/R/IQ receiver can be strapped to pipes or mounted on brackets. Up to 32 sensors can communicate with one XW/R/IQ receiver sited up to 75 m (80 yds) away (dependent on the installation environment). The XW/R/IQ plugs into an IQ2 series or IQ3 series controller’s RS232 port.

The TW/.., PCW/.., XW/R/IQ wireless system consists of up to 32 wireless sensors (consisting of a mix of TW/.. and PCW/..) transmitting to an XW/R/IQ receiver. The XW/R/IQ receiver plugs into the local supervisor port of an IQ2 or IQ3 controller, and writes the sensors’ values and their status to defined analogue nodes and digital points within the IQ controller.

Each wireless sensor is identified by a unique 3 byte (16,777,216 variants) number, which is printed on the sensor’s identification label. Using the ACCW/CONFIGKIT configuration software, the XW/R/IQ should be programmed to allocate each identification number to an analogue node within the local IQ, or within another IQ on the local Lan. The selected analogue node has associated digital points for reception of the sensor’s status

Wireless Sensors

Wireless sensors measure the required parameters and transmit them regularly to the XW/R/IQ receiver.

The sensor is powered by a lithium battery. If a low battery condition occurs, it will be indicated in the sensor’s digital status bits. The batteries are not field replaceable, and when the battery has run down (voltage <3 V), the sensor should be returned to the IQ system supplier for battery replacement.

The 8 digit identifier number is printed on a label mounted on the battery of the TW/.. sensors and the surface of the PCW/.. pulse counters. A second removable label is mounted on the TW/..

sensor’s pcb. and is provided for the installer’s own use.

TW/S Space Sensor

The TW/S is a wall mounting thermistor space temperature sensor. The TW/S housing consists of 2 parts; front panel, and back plate, and can be either mounted onto a flat surface, or flush mounted using a standard wallbox. The two halves of the housing can be separated by inserting a broad bladed screwdriver into the lower slot and twisting.

PCW/.. Pulse Counters, XW/R/IQ Receiver

The unit may be mounted using an optional stainless steel bracket

(ACCW/FK/SS), or using the plastic bracket supplied with the

XW/R/IQ only, or alternatively it can be tied to a pipe or other structure using a plastic cable tie.

plastic cable tie plastic bracket supplied

(XW/R/IQ only) horizontal pipe vertical pipe

PCW/.. Pulse Counters: Whenever monitoring hot water systems it is not advisable to mount the pulse counter directly on the pipe without intervening insulation. A PCW/.. pulse counter is supplied with a 2 metre (2 yds) screened cable for connecting to the input contact.

The input may be provided by a volt free contact, opto-coupler, or transistor switch.

The PCW/.. pulse counters (/METER and /STATUS) will count the number of pulses received and transmit the accumulated value to the receiver. The count will roll round back to zero at 16777215.

The PCW/METER sends the value every minute and is compatible with receivers of serial number 2404701 and greater.

The PCW/STATUS also sets one of its status bits to the state of the input. It is designed to monitor non-fleeting inputs; the state must last longer than 5s. It sends the value and status on change of input state and every 4 minutes. The PCW/STATUS is compatible with receivers of serial number 2505157 and greater.

XW/R/IQ receiver: The XW/R/IQ receiver is supplied with a 4 m

(4 yds 1’) screened cable for connecting to an IQ controller. If a longer distance is required (up to 15 m, 16 yds), then an RJ11 extension cable may be used. The receiver is powered from the controller.

Optimum range will only be achieved if the antenna is kept clear of metallic objects such as water tanks and other conducting surfaces.


The transmitters will transmit in a short burst approximately as follows:

TW/S: every 2 minutes

TW/P: every 2 minutes

PCW/METER: every 1 minute

PCW/STATUS: every 4 minutes, and on change of input state with a triple burst (with 1s separation).

In between transmissions they will switch into low power ‘sleep’ mode.

The transmission consists of the sensor identifier, the value, and the sensor’s status.

Each XW/R/IQ receiver must be programmed with a 32 entry internal look-up table of its associated sensors.

T r a n s m i t t e r

A d d r e s s

A n a l o g u e

N o .

N o d e

A 2 0 1

O / S A d d r e s s

E n t r y 8

Each entry in the table associates a sensor with the XW/R/IQ receiver and references the sensor’s 8 digit identifier to both its target analogue node, and its target outstation.

Note that the nodes used will have to be created in the strategy for IQ3 controllers (they always exist in IQ2xx controllers).

Normally the outstation number will be the device address of the outstation to which it is connected, but it may be the address of another outstation on its local Lan. If it uses another outstation then the local outstation’s proxy CNC must be set up (i.e. the local supervisor port address must be non-zero).

The sensor sends its status bits to the receiver: all sensors send battery fail status, TW/.. sensors send the sensor fail status, and the PCW/STATUS sends the input state. The receiver will also detect if the sensor is failing to update within 25 mins, and generate a loss of reception status which it will send with a value of -100. The receiver produces the sensor status bits.

R O L H bit 7 6 5 4 3 2 1 0

0 0 0 0 0 1 1 0 loss of reception sensor failure (TW/..) low battery input state (PCW/STATUS)

On receipt of a value from the sensor the receiver will send the sensor value to the analogue node and outstation address set up in appropriate entry in the look-up table, and it will send the status bits to the alarm byte associated with that node in IQ2 and

IQ1 series controllers (e.g. A200 uses byte 240 by convention

- see IQ Digital/Analogue Array Reference Card, TB100522)

For IQ3 controllers the analogue node has to be created when engineering the strategy. The four status outputs, Read (R),

Outside Limits (O), Low (L), High (H) corresponding to the status bits (3 to 0 respectively) are provided in the analogue node module (see compatibility section).

The status bits are sent to the local controller using text comms

(if transmitting to another controller, IC Comms wil be used).

TW/.., PCW/.., XW/R/IQ Data Sheet TA200780 Issue 2 07/07/08 3

TW/.., PCW/.., XW/R/IQ Data Sheet




The recommended maximum range between a wireless sensor and the XW/R/IQ receiver is 75 metres (80 yds).

All sensors transmit on the same frequency band (433.05 to

434.79 MHz).


The signal propagation within the building also depends on :

Reflection from flat surfaces such as metal cladding, galvanized roofing, foil backed plaster board.

Radiation from thin conductors such a pipe work, electrical wiring, steel.

Reflection and re-transmission can result in a standing wave being set up in the area. If the receiver happens to be in a null of the wave, moving its position slightly will result in stronger reception.

Absorption by lossy materials such as damp concrete, stone work, and people. High RF barriers are paper (e.g.

books), concrete (floors, outer walls), and metal

(elevator shafts, cabinets).

Generally, the higher the transmitter is mounted, the further the signal will reach. It is recommended to mount the transmitter above partition height if possible.


It is not recommended that other equipment operating over the same frequency band be used in the same environment (e.g.

amateur radio). It is also advisable to keep the wireless sensors and XW/R/IQ away from other sources of interference e.g.

computer (>1 m, 1 yds), microwave ovens, switch mode power supplies.

ACC/RW/IQ Repeater

The repeater can be used to increase the maximum distance between a transmitter and the receiver. Thus, if the repeater is placed within 75 metres (80 yds) of the transmitter, the receiver can then be 75 metres (80 yds) from the repeater which increases the total distance from the transmitter to the receiver to 150 metres

(160 yds).

In a white walled building (a building with rooms thermally insulated with foam and aluminium sheets; food industry) best performance may be found by mounting the repeater in the loft space above the white walled area. There will always be a degree of leakage in a white walled building, and propagation is much easier out of the room, in a loft space, compared to between white walls.

Enclosure: The repeater is supplied in a compact diecast wall mounting enclosure.The bracket supplied should be used to secure the unit to a wall such that the antenna is vertically polarised.

Input Power: The repeater requires 230 Vac 50 Hz at

<1W. It is supplied with a flying 230 Vac power cable with a standard 13 A fused plug.

The repeater contains a half duplex radio port. It has an intelligent store and repeat function, holding the address and message counter of the repeated message, and barring them from repeat within a given time window in the event of a second repeater being within range. New messages with a changed address or message count will be repeated. Messages not obeying the correct protocol, or with corruption, or with checksum failure will not be repeated.

Network identification

Note that the XW/R/IQ will not respond to w comms (i.e. it will not identify itself as a networked device when polled).

The XW/R/IQ receiver must be configured before completing the installation. This is done using the ACCW/CONFIGKIT configuration kit consisting of a CD containing the XW/R/IQ configuration software and the configuration cable (EJ105784).

The software should be installed on a PC, and the XW/R/IQ connected to the PC’s RS232 port using the configuration cable.

The adaptor cable has 3 connectors, a 9 way D type female for connecting to the PC’s RS232 port, an RJ11 socket for connecting to the XW/R/IQ, and a 2 screw terminal plug for connecting to an

IQ’s 24 Vdc auxiliary output supply.

The configuration software will be installed in Program files/Project1 by default. It will appear in the Start/Programs menu as Rtcom-

Trend/Rtcom-Trend. Once the program is started it will display the following page.

PIN number in use (if any) look-up table communications window

The configuration software enables the look-up table stored in the XW/R/IQ to be configured. There are 32 rows in the table, one for each sensor entry. Each row in the table has the following parameters.


Transmitter Address: An 8 digit identification number, unique to each transmitter (e.g. 00016932 will be displayed as 16932). The identification number is shown on a label attached to the wireless sensor.



Analogue Node Number: This is the node within the IQ controller to which the sensor’s value will be written. It must be configured.

Outstation Address: This is the controller address on the local Lan. It is normally the address of the local controller, but it can be the address of another controller on the local

Lan. A value of zero is invalid and will cause that sensor entry to be delivered.

Note that the sensor value is then sent to the address, analogue node xx in IQyy (xx is an analogue node number, yy is a O/S address).

If the value is to be sent to another controller then the local controller’s local supervisor port address must be set greater than zero.


Current value: The last value received from the sensor; the value is transmitted every 2 minutes (for TW/S), every 1 minute (for TW/P, PCW/METER), and every 4 minutes (for PCW/STATUS; plus on every input change).


Note that for PCW/METER or PCW/STATUS the initial value should be recorded as it will vary from unit to unit.

The pulse counter has been designed not to have reset capability in order to prevent fraud.

Received Time: The time the last value was received from the sensor.

The full configuration details are covered by the XW/R/IQ

Configuration Software Manual, but the sequence given below covers the main steps:




The XW/R/IQ receiver and its wireless sensors should be installed according to their installation instructions.

On the ‘Protocol’ menu ensure that the ‘Trend Protocol’ option is selected (✔).

On the ‘Port’ menu select the port number of the RS232 port to which the XW/R/IQ is connected; the selected


port number will then be indicated by a tick (✔).

If the controller has a password set up, specify a PIN in the XW/R/IQ that matches one of priority level 95 or greater set in the controller. On the ‘Configuration’ menu select ‘Program PIN Number’ and enter the PIN.

If the controller does not have a password set up, then on the ‘Configuration’ menu select ‘disable PIN code’.

Note that if the sensor values are to be sent to several controllers then all these controllers must have the same password setup

(>=level 90).


To check the existing configuration table within the XW/R/

IQ, on the ‘Configuration’ menu select ‘Read Channels 1-

16’; this will display the information in the first 16 entries in the table. Then ‘Read Channels 17-32’ to read the


information in the last 16 entries.

The configuration menu may be amended or cleared and set up from scratch.

The available sensors can be found from the communications window; on the ‘Configuration’ menu select Output Mode and ‘0 - All transmitters [binary]’. This will change the communication display into a more legible format. It will show the communications from all the sensors that the XW/R/IQ can receive.

Each communication shows the Address (identification number) of the sensor and its current value:

Multiple Sensors and Receivers

XW/R/IQ receivers will receive communications from all wireless sensors within range (nominally 75 metres, 80 yds, but this can be affected by the installed environment and by the use of repeaters). Thus in the diagram below both XW/R/IQ receivers will receive from all wireless sensors 1, 2, and 3.

Plug the XW/R/IQ receiver into its IQ controller.

The system configuration engineer can decide how the XW/R/IQ receivers can be configured to select which wireless sensors each of them receives.

If the engineer wishes, a wireless sensor can be received by more than 1 receiver; this will enable the same value to be present in 2 controllers, hence a degree of redundancy can be provided. Alternatively the value may be sent from controller to controller by IC comms.


Controllers: The XW/R/IQ is compatible with IQ2xx controllers and all IQ3’s. The standard XW/R/IQ relies on the IQ controller to supply its power from the RS232 local supervisor RJ11 socket.

This is available on all current IQ2s and IQ3s except for the IQ251.

Connection to an IQ251 (or any other IQ2 without 24 V output supply available on its RJ11) requires the use of the additional adaptor cable RD/SDU-ADAPTOR IQ2xx.

Note that the XW/R/IQ is not compatible with /ADL, /ATM or

XNC220 controllers as the RS232 port is already in use.

NOTE that the PCW/METER pulse counter is only compatible with XW/R/IQ receivers of serial number 2404701 and greater, and that the PCW/STATUS is only compatible with XW/R/

When used with IQ3 any analogue nodes used have to be created using SET. An example strategy for a wireless sensor input is given below. The sensor failure status (TW/.. only) and loss of reception status are passed through the internal sensor module, but the battery low status and the digital input status (PCW/STATUS only) are monitored separately by internal digital inputs.
