Connecting room thermostats per zone

The SCB-10 is fitted with three R-Bus connectors. They can be used to
connect room thermostats per zone. The R-bus connectors are related to
the other zone-specific connectors on the SCB-10.The R-Bus connector
supports the following types:
R-Bus thermostat
OpenTherm thermostat
OpenTherm Smart Power thermostat
AD-4000003-01
On/off thermostat
The software recognizes which type of thermostat is connected.
