The Siemens RDL131RF.ST wireless programmable room thermostat is a set comprising a thermostat and a wireless output module for heating control via OpenTherm communication in both residential and light commercial applications. The regulation can be used as purely spatial or weather-compensated according to the outdoor temperature (depending on the connected sensor). Available modes include COMFORT, SETBACK, AUTO, and PROTECTIVE MODE, including an absence mode with adjustable start and end. Control is facilitated by an e-ink display with touch buttons, the option to lock controls, and a start/stop optimization function for stable temperature comfort. Settings can be made locally or via the Siemens QuickConfig app.
