Functionality
An RS-WMB (Room Sensor) or RD-WMB (Room Display)
connects to a controller (IQeco) via its wall mounting bus
(WMB) connector. This two wire connection carries both signal
and power for the unit. The values from the controller that the
RD-WMB can display and change are fixed, but will only be
enabled if set up in the controller.
Both RS and RD include a temperature sensor and will output
the temperature in either °C or °F. There is an option to include
a humidity sensor.
The RD-WMB enables the setpoint to be displayed and adjusted
locally. It also provides for the display and adjustment of fan
speed and occupancy. The fan button can also be configured to
perform adjustment without displaying the fan speed icons (e.g.
for controlling other equipment such as window blinds).
HARDWARE
Unit: The unit consists of a plastic back plate with a plastic clipon main module. The back plate has several mounting holes
enabling it to be used with a standard UK electrical back box, a
standard US or Danish utility conduit box, or 60 mm wall outlet
box. It can be mounted directly on a wall or on a front panel.
Space must be left around the unit for airflow and access to
remove the main module.

Both units are available with temperature sensor only or
temperature plus humidity and/or CO2 sensors.
The RD-WMB also has an LED display and 4 control buttons.
Input Power Supply: The power for the unit is supplied from
the controller by way of the WMB wallbus.
Backup: The Settings Menu settings are stored in EEROM
which is non-volatile to power interruptions.

RS-WMB, RD-WMB
Note: Changing the address switch setting may stop
communications.
Firmware
The firmware in the RS/RD-WMB controls its basic functionality
(e.g. what is displayed, the results of pressing the buttons)
Normal Operation
Startup Reset: The RS/RD will perform a reset cycle when
power is applied. The RD-WMB will first display a Trend page
followed by a page showing the unit firmware version and WMB
bus address.
Where the item is editable, one of the function keys is labelled
(edit). Selecting
enables the value to be changed using
the decrease/increase keys. One of the function keys is now
labelled
so that when the editing is finished selecting
will
accept the new value and return to More display mode.
Settings Menu: Pressing the two function buttons
simultaneously and holding down for 5 seconds will cause
the unit to enter the Settings Menu. This enables changes to
be made to the way the RS/RD-WMB operates. First a PIN is
requested:
ENTER PIN - Enter the 4 digit PIN using the decrease/
increase buttons.
If communications with the controller are unsuccessful for 3 to 6
minutes the RD-WMB screen will display ‘ERR’ (error).
If successful the following functions can be stepped through in
the appropriate direction using the decrease/increase buttons.
Illumination state (RD-WMB only): By default the display’s
backlight will be off. Pressing any button will turn on the
backlight. About 1 minute after the last button is pressed the
backlight will turn off.
WMB ADDRESS: This is the address of the RS/RD-WMB
on the WMB (set to 2 by default).
Value Displayed: By default the RD-WMB display will show
local temperature but the unit can also show Temperature
Setpoint, Humidity, CO2 concentration, and Outside Air
Temperature according to which options have been set up in
the RD’s Settings Menu, and what is available in the controller.
Use of Buttons
Occupation override: By pressing the
button the user will
override the occupation state. If the current state is occupied it
will override it to non-occupied, and display the unoccupied icon;
the button will change to
to indicate the state is overridden.
Pressing the
button will return the occupied icon to the
display, and change the button back to
. If the current state
is unoccupied then the opposite sequence will occur (press
button, display occupied icon with button
; press
button,
display unoccupied icon with button
).
Fan: Pressing the
button will allow the user to override the
fan speed control. Normally the fan will be under automatic
control, and pressing the fan button will switch it into manual
control. The way the fan operates is dependent on the type of
fan control (see Fan Configuration below). For a 2 speed fan
the absence of the fan icon indicates the fan is off, and the
indicates the fan is on. For a multi-speed fan, the first press
switches the fan off, and subsequent presses step through the
available fan speeds (e.g. low, medium, high), and the next
press sets it back to automatic control. The fan off condition can
be shown by
OFF. The low, medium, high, manual speeds,
and automatic control state are shown by the fan
icon in
conjunction with
,
,
, AUTO respectively.
‘More’ Display Mode: Pressing the decrease and increase
buttons simultaneously will cause the unit to enter the ‘More’
Display Mode. The choice of items to be shown in the ‘More’
Display Mode can be selected in the Settings Menu. If all items
are selected, pressing either decrease or increase will step
through the following in the appropriate direction.

Use with IQeco
The fan can be operated in one of 7 modes; modes 0 to 6.
Connecting the RS/RD-WMB to the IQeco makes additional I/O
channels available to the controller. The RS/RD is considered
to be an additional I/O module (I/O module 2) of WMB display
type.

Note: For a controller to make use of the RS/RD in its strategy, it
must be configured with a WMB display type I/O module.
This gives additional I/O channels (the number being dependent
on the RS/RD-WMB type), and some fixed mapping to the
controller variables.

Description
channel
I/O module 2 The
RS/RD-WMB’s
channel 1
temperature sensor is scaled
into °F, or °C according to
the units set up in S31 in
the controller. To display a
temperature value on the RDWMB the required value must
be linked to S31 which is read
by the RS/RD-WMB.
In the standard strategies S31
is used for both reading and
displaying the temperature
which allows a RS/RD-WMB
to be connected without the
need to modify the standard
strategies.
I/O module 2 To display a humidity value
channel 2
on the RD-WMB the required
value must be linked to S32
which is read by the RD-WMB.
I/O module 2 The RS/RD calculates the
channel 3
dew point value from its
temperature and humidity
values. It is calculated in °F,
or °C according to the units
set up in S31 in the controller
The dewpoint value cannot be
displayed on the RS/RD.
The sensor values are sent to controller every 15 s.
To read one of the RS/RD’s values into the strategy an external
sensor with a sensor type of ‘112, WMB pre-scaled’ (which is
a pre-configured sensor type that leaves the value received
from the RS/RD-WMB unchanged) must be configured to read
its input value from the relevant channel of I/O module 2. This
value can then be used in the strategy as required.

in the controller. ON = occupied.
Fan Speed
Input to/output from RDWMB. The fan button ( ) will
step through the fan speeds
available according to the Fan
Configuration. The new value
is sent from the RD-WMB when
the button is pressed, and sent
from the controller if K45’s value
changes in the controller. The
value of K45 is set as follows:
0 = off, 1 = Low Speed or On
(Mode 2), 2 = Medium Speed, 3
= High Speed, 4 = Auto, 255 =
On (modes 1 and 2).
When creating strategies for use with RS/RD-WMB it is
recommended that sensors 32 to 39 are not used as they are
allocated for possible future developments
Note: The RS/RD-WMB’s internal sensor values are monitored
by the controller, and can then be processed by the controller’s
strategy before being made available for the RD-WMB to display
from the sensor module outputs. So the value displayed can
be different to the value measured by the RD-WMB’s internal
sensor .
Error Display: If the space temperature value is not received
within 3 to 6 minutes the display will show ‘ERR’.
PIN (RD-WMB only)
The unit is pre-programmed with a default 4 digit PIN to protect
entry to the Settings Menu.

Compatibility
The RS/RD-WMB is compatible with IQeco with firmware
version 2 or greater.
IQeco standard strategies can use the RS/RD-WMB without
any further engineering. For a custom strategy to make use
of the RS/RD-WMB it must be configured with a WMB display
type I/O module, and (for RD-WMB) it must use the mappings
described earlier.
