Steca TF B202

Fresh water controller (compact)


The particularly cost-effective Steca TF B202 fresh water controller is suitable for heating drinking water directly and hygienically using the instantaneous water heater principle for fresh water stations in the range of 0-20 l/min, 0-40 l/min and 0-80 l/min.

The new intelligent and self-learning control algorithm developed in the Steca fresh water laboratories enables a highly efficient energy transfer from the primary buffer to the secondary drinking water circuit with the aid of a multifunctional Huba Control flow sensor for flow and temperature detection. For OEM customers, there is also a flexible option of integrating alternative analogue flow transmitters.

The Steca TF B202 demonstrates its versatility by facilitating speed control of both standard glandless pumps and innovative high-efficiency pumps. The Steca TF B202 can also control a circulation pump. The controller offers time, temperature or pulse dependent control methods for this purpose.

Due to its small dimensions, the Steca TF B202 is especially easy to integrate into compact fresh water stations. The specially designed switching power supply guarantees the greatest possible efficiency and economical operation. This reduces self-consumption to a minimum. The variable input voltage range ensures universal and worldwide use. An electronic load control protects against overloading and installation errors.

In addition to controller operation, the Steca TF B202 performs important system monitoring and safety functions. This can be used to guarantee a continuous and safe hygienic drinking water supply. Special error messages are displayed for quickly rectifying faults.
