The ecoSTER (TIS Tronic 297) device is a remote control panel with added room thermostat function and it is designed for simple temperature control. Besides thermostat function it enables readout and edition of full range of parameters for boilers, heat pumps, air handling and heat recovery units etc. Apart from parameter settings the user can also change different work modes, see the fuel level or alarm notifications. There is also a tool to set individual time schedules for day and night temperatures. This device works together only with boiler controller and WiFi module. When the weather sensor is in use for boiler or mixing circuit control the ecoSTER can then automatically adjust the heating curve in order to heat up the boiler or mixer circuit. It also has the function of “Hotel mode” which is used for blocking boiler or other thermostat parameters on certain remote control panels.
