System Operation
DT92E and ST9120C both use 2-way communication on an 868MHz
radio frequency (RF) band to control the heating and stored hot water
system.
ST9120C operates as the control hub of the system, and DT92E is free to
be positioned anywhere in the living space.
This functionality is ideal for upgrading existing systems without a room
thermostat to ensure compliance with Building Regulations. It is also
ideal for new or refurbished systems, where running mains cable from the
timer to the thermostat and back to the boiler is difficult or impractical.
