Wireless room thermostat eSTER_x40

eSTER_x40 is a battery-operated room thermostat designed for wireless cooperation with an external ISM_xSMART radio transmission module from PLUM company. Thermostat is installed in a selected room where we can set required temperature. Two-way ISM radio communication has been applied, allowing for transmission of information from main controller to thermostat about the fuel level in tank, alarm states of controller and external temperature value. Thermostat on backlit LCD display shows information about room temperature value, selected operation mode, current time and date with simultaneous clock synchronization with main regulator.

Application, advantages and benefits:

• Room temperature setpoint adjustment and operating mode selection
• Backlit, dedicated LCD display
• Application for PLUM controllers of ecoMAX, ecoVENT, ecoTRONIC series with connected ISM_xSMART module
• Wall-mounting in any room without wires
• Wireless, bidirectional ISM transmission with controller
• Can be moved to any location within range
• Stable ISM transmission range in a residential building
• Boiler mode ON/OFF
• Work monitoring system
• Weekly time schedules
• Notification of the need to clean boiler
• Setting remote boiler temperature
• DHW temperature setting
• Fuel quantity preview
• Alarm signalling
• Remote room temperature setting
• Automatic shifting of heating curve
• Room temperature correction
• Information on display about operating mode

Full radio ISM two-way communication:

• Cooperates with a two-way radio transmission module ISM_xSMART with LBS system in ISM band,
• Provides full configuration of controller menu from any room,
• Keeps room temperature set,
• By downloading data from regulator it informs about level of fuel in fuel tank, alarm states and boiler monitors, burner operation and the need to clean it, as well as external temperature value,
• Switches boiler on and off and ensures constant time synchronisation with controller,

System xSMART:

• LBS system – minimize interference with other devices,
• Access to operating parameters and time schedules from user and service menus,
• Selection of control modes and full configuration of controller parameters,
• Durable capacitive buttons,
• Battery saving mode, battery discharge indicator and radio signal strength,
• Parental lock,
• Simple pairing with devices,
• High operational stability, thanks to constant monitoring of connection quality,
