System limitations
• Only one Hot-Cool module BT-HCM02 RF per System – 1 output only
for humidity drier
• 4 hydraulic circuits per System
• Only zones containing only electrical heaters can do heating when the
System is in cooling mode
• Mix different modes of heating in the same room is not recommended
as the regulations embedded in each receiver are not synchronized
• With a Central Unit BT-CT02 RF, it is highly recommended to use devic-
es paired in hydraulic circuit directly on the BT-CT02 RF. Output usage
of BT-M6Z02 RF and BT-HCM02 RF is only possible on small System
(Only 1 BT-M6Z02 RF and 1 BT-HCM02 RF)
BT-CT02 RF software update
On www.wattswater.eu homepage, you can find files allowing updating the
software of the Central Unit BT-CT02 RF. The procedure should be performed while
the BT-CT02 RF is plugged to the 230V wall support.
• Unzip in a microSD the 3 files (wifi.ini, wifi.hex, update.bin)
• Insert the microSD
• Press on Update Firmware in the installation menu
• Wait the end of the software Update procedure and wait at least 1mn
before removing the microSD
Configuration of the remote control
of the central
Except the installation configuration, all the functions of the Central Unit are
available on:
• The web site www.wattswater.eu
• On Watts Vision application available on Apple store (iOS)
• On Watts Vision application available on Play store (Android)
The remote control configuration should be performed in 3 steps after configuration
of you heating and cooling system.
1 Connect the central to a wifi router. Menu Installation/wifi. The connec-
tion can be manual or automatic. When the wifi connection succeeds,
the wifi menu displays 1/2 status and a green flag.
2 From the web site or the application, create an account with your email
and a password
3 Link your central to your account. In the application, request the send-
ing of a pairing code on your mail box. Enter the code in the wifi menu.
4 After a few minutes, your central should be displayed in the application.
The wifi menu of the central should display 2/2 status.
