3 Pair the two BT-M6Z02: In this configuration, one BT-M6Z02-RF (called “Main”)
will centralize the information of the other BT-M6Z02-RF (called “Sub”).
Refer to Centralized Installation of the user guide
4 Pair in slave mode the BT-HCM02 RF to the BT-M6Z02 RF master.
* In this application each BT-M6Z02 RF is connected to a circulating pump.
DIP SWITCH #1 Configuration: OFF = LOCAL. In case of an installation with more than one BT-M6Z02 RF
connecting box and only 1 circulating pump, DIP SWITCH #1 Configuration: ON = GLOBAL on the
BT-M6Z02 RF that drives the circulating pump (= BT-M6Z02 Master)
** In application with humidity drier (for system limitation ref. to pag. 33) connect it to the output of Hot/Cool
module for triggering it on/off and managing relative humidity (%). In this case it is necessary to install at
least 1 thermostat BT-D02 RF with Humidity Sensor and locate it in a central area of the installation.
Note: one humidity drier per System – refer to SYSTEM LIMITATIONS (pag. 33).

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 devices 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.
