Solar Thermal Controller

Steca TR A301 PWM

The Steca TR A301 PWM controller was designed for use with new high-efficiency, cost and energy saving solar heating pump technology. This latest generation of electrically commutated circulation pumps have an integrated frequency converter and a permanent magnet motor. The PWM control signal must be specially activated in order to control this type of high-efficiency ECM pump. With this pulse width modulated DC square-wave signal the Steca TR A301 PWM controller can automatically exactly adapt the pump speed via a separate control cable to match the continually changing requirements of the system.

In addition to PWM speed control of the solar circulation pump, the Steca TR A301 PWM also allows hydraulic compensation of the solar energy system via Grundfos Direct Sensors^TM.

The clear, graphically animated display provides visualisation of the current operating status and also the complete solar circuit. The consistent use of pictograms helps make the controller easy to operate.

The controller also performs important system monitoring and safety functions to ensure safe and long-lasting operation of the entire system.

The operational safety of the system is supported by a sophisticated fault diagnosis. The multi-coloured LCD backlight ensures quick and safe location of occurring errors and facilitates quick troubleshooting.
