Steca TF A603 MC+Domestic hot water controller (stand-alone)DescriptionFeaturesDownloadsTechnical data Compare productsDescription
The Steca TF A603 MC+ is a stand-alone domestic hot water controller for heating drinking water directly and hygienically using the continuous flow heater principle.
With an all new control algorithm, the Steca TF A603 MC+ controller is well equipped to channel energy from a buffer storage tank to the drinking water circuit with particular speed and efficiency. Owing to its auto-adaptive control algorithm, the controller is capable of adjusting to the specific conditions of each system as soon as the equipment is initially set up, ensuring a constant hot drinking water temperature to address hygienic considerations.
A primary objective in this regard is to keep the return temperature to the buffer storage tank as low as possible in order to additionally increase the efficiency and yield of the solar system. This is supported by a zone feed function using water from the buffer storage tank via a 3-way switching valve.
The Steca TF A603 MC+ can also control a circulation pump. In doing so, time-based, temperature-based, or pulse-based control is possible.
A particular highlight of the Steca TF A603 MC+ controller is the fact that the unit saves the system's operating data to a SD card. Animated control circuits are displayed on the unit's large graphic display to visualise the respective system's operating statuses. The Steca TF A603 MC+ includes six inputs for recording temperatures or pulse values as well as an additional Grundfos Direct Sensors™ input for combined temperature and flow rate measurement. Pumps and switching valves are controlled via three outputs, some of which are speed controlled.
Note: The Steca TF A603 MC+ controller is only available in conjunction with domestic hot water systems approved by KATEK.
