Mit dem EcoTimer übermitteln Sie ein individuelles Zeitprogramm auf die Bediengeräte FKS, WKS und WFS. Die App stellt eine Bluetooth-Verbindung mit dem Regelgerät her. Wurde das Raumbediengerät von der App erkannt ist es möglich, das Bediengerät umzubenennen sowie wöchentlich wiederkehrende, tagesindividuelle Zeitprogramme zu erstellen und diese auf die Raumbediengeräte zu übertragen. Die App ermöglicht die zeitabhängige Steuerung der Betriebszustände „Aus“, „Eco“ und „Komfort“. Die Komfort-Temperatur wird über die Einstellung des Drehrades am Raumbediengerät eingestellt. In der Eco-Funktion wird diese Temperatur um einen, über die App, frei wählbaren Wert abgesenkt. Im Modus „Aus“ ist ausschließlich der Frostschutz aktiv, der dafür sorgt, dass eine Raumtemperatur von 7°C nicht unterschritten wird. Weiterhin können die bereits geschriebenen Zeitprogramme vom Raumbediengerät ausgelesen und angepasst werden.
