Daisy chain connection
The thermostats in the example are connected in series and only one
cable needs to be routed from the room controller and slave module
(if available).
This method reduces the total length of cable needed in the system.
Direct connection to room controller and slave
module
Every thermostat in the example is connected to the room controller
and slave module (if available) with its own cable.
Connection to attached star module
The star module is attached to the room controller and slave module
(if available) adding extra connection terminals to the system. Each
thermostat in the example is connected direct to the room controller,
slave module (if available) and star module.
Connection to cable connected star module
The star module is connected to the room controller and/or slave
module (if available) with a cable, using two of the extra connection
points. Each thermostat in the example is connected direct to the star
module, except one that is connected with daisy chain.
Connect communication cable
Connect the communication cable to either the room controller, slave
module, and/or star module.
