Use with IQ4
The IQ4 can be congured either by using the SET strategy
block (recommended), or by manual conguration.
Using the SET strategy block (recommended):
▪ Add the SET Strategy Block to the strategy. The
strategy blocks are located in the ‘Standard Block’
section of the Strategy Library in the ‘WMB Room
Modules’ section. There is a separate section for RS
and RD, each section has 4 blocks, one block for each
product version (-T, -TC, -TH, -THC).
▪ Set the Wallbus Interface module’s ‘Address’
parameter to the RS-WMB, RD-WMB’s address on
the Wallbus (default is 2.)
▪ Ensure that the Wallbus Interface module’s inputs and
outputs are linked to the required modules.
Important: When using the strategy block (as explained
above) some PVs write their value to the RD-WMB and will
overwrite changes to that PV made in the RD-WMB’s Settings
Menu. If this is not required, remove the PV from the Wallbus
Interface module’s inputs. See RS-WMB, RD-WMB Data
Sheet (TA201348).
Adding the strategy block will automatically add the Wallbus
Network module, and create an instance of the Wallbus
Interface module.
The strategy block congures the inputs and outputs of the
Wallbus Interface module - see RS-WMB, RD-WMB Data
Sheet (TA201348). This conguration should be suitable for
most applications. If different functionality is required the
strategy will need to be modied after the strategy block has
been added.
Manual conguration:
▪ Add the Wallbus Network module to the strategy
(default values will be suitable).
▪ Add a Wallbus Interface module to the strategy.
▪ SET the Wallbus Interface module’s ‘Address’
parameter to the RS-WMB, RD-WMB’s address on
the Wallbus.
▪ Set up the Wallbus Interface module’s input and
output connections to specify the PV (PV Index) in the
RS-WMB, RD-WMB that they are to be linked to as well
as their other parameters. The RS-WMB, RD-WMB’s
PVs are described in the RS-WMB, RD-WMB Data
Sheet (TA201348).
▪ Link the Wallbus Interface module’s inputs and outputs
to the required modules in the strategy.
For details of the Wallbus Network and Wallbus Interface
modules see the IQ4 Conguration Manual (TE201263).
The controller strategy must be congured using SET v7.0 or greater. For details of using SET - see the SET Manual
(TE200147).
For IQeco
I/Omodule 2 must be set up with WMB display type. Its
channels are connected to external sensors with scaling type
‘112, WMB pre-scaled’ as follows:
Channel 1: Temperature
Channel 2: Humidity*
Channel 3: Dew point*
*Humidity and Dew point on -H, CO
2
on -C versions only
The fan can operate in one of seven modes, this is set in I/O
module 2, Fan Conguration parameter (f). It is set up in the
RD by the controller on power up.
Mode Description
0 no fan
1 2 position fan (OFF, ON)
2 3 position fan (OFF, ON, AUTO)
3 4 position fan (Off, 1, 2, 3)
4 5 position fan (Off, 1, 2, 3, AUTO)
5 4 position blind
6 5 position blind.
The strategy must comply with the following module mappings
between strategy and RS-WMB, RD-WMB .
