12. WIRELESS PROBES, INSTALLATION AND CONFIGURATION

12.1 Type of installation and wireless probe
electrical connections
Wireless probes are available for systems where standard wired probes
cannot be used, for example modifi cations to existing installations. An
Access Point (CAREL P/N: WS01AB2M20) is used to connect up to four
wireless probes.

HeaterSteam/Access point connection:
To connect the humidifi er to the access point, use the Fieldbus
connection on terminal M3 (M3.1: Tx/Rx-, M3.2: Tx/Rx+, M3.3: GND):
Note: the devices have a range of around a hundred metres in a free
space, i.e. without any obstacles. In a closed space, the range varies
considerably depending on the type of environment and the surrounding
objects (shelves, metal partition walls etc.).
If installing multiple wireless probes, the controller will calculate the
weighted average between the various probe readings, depending on
the settings made by the user and the defi ned probe groups. Also see
paragraph 7.4.3 Wireless probes. The controller also displays (locally only)
the battery and signal level for each probe (screen index D05-D08).
The table below shows the part numbers and descriptions of the Carel
devices that can be used:

12.2 Wireless probe installation

The main steps for installing the wireless devices are:
•
power up the Access Point (12/24 Vac/dc ±10%m, 100mA) and
complete the initialisation procedure, creating the network and
selecting the channel;
•
after having opened the domain on the Access Point, complete the
binding procedure so as to uniquely identify each probe.

Recommended Carel wireless probes are the room (WS01G01M00) or
industrial versions (WS01F01M00), both of which measure humidity
and temperature. The type of installation is shown in the fi gure below
(referring to four wireless room probes):

The address to be used by the Access Point is set using the dipswitches
on the device, and is the following:
L1 L2 L3
Rx- Rx+ GND
DIP 1-2-3 selezione indirizzo di rete
1 2 3 4 DIP 4 selezione baud di rete + - - + G
DIP:
T1
This assigns the address 2 to the Access Point, with a baud rate (Bit/sec)
of 19200 (N82). The addresses of the four serial probes, on the other hand,
must be set as shown in the table below:
Address
1
Probe 1 16 0
Probe 2 17 1
Probe 3 18 0
Probe 4 19 1
Remember to verify the quality of the wireless signal between the Access
Point and each wireless probe.
For a complete description of the installation procedure, see the Carel
manual on the corresponding probes and Access Point.
To confi gure the probes, go the screens: Ec03, Ec04, Ec05, Ec06 and Ec07,
described in paragraph 7.4.3 "Wireless probes".
In particular, screen Ec03 is used to enable the wireless probes connected
to the Access Point, knowing that addresses 16, 17, 18 and 19 are Probe 1,
Probe 2, Probe 3 and Probe 4 respectively.

Note: the wireless probes are managed on the heaterSteam
titanium version.
