2. General information
Room thermostat eSTER_x40 is designed for
wireless cooperation with external radio
transmission module ISM_xSMART, which is
wired to the main controller. The thermostat
is installed in a selected room, eg a living
room, and is designed to maintain a preset
room temperature by sending a radio signal
to a module connected to the main
controller. The implemented encrypted, two-
way radio communication allows the
transmission of information from the main
controller to the thermostat, including the
fuel level in the fuel tank, alarm statuses of
the regulator and external temperature
values. The thermostat on the backlit LCD
display shows information about the room
temperature value, selected operating mode,
current time with simultaneous clock
synchronization with the main controller.
Radio communication: 1 - eSTER_x40 thermostat,
2 - ISM_xSMART radio module, 3 - main
controller.
