Description

The Steca TR A501 T solar thermal controller has been developed to be especially efficient in the widest possible range of aplications. It is an ideal solution for all single-circuit systems. The compact designer casing can be superbly integrated into solar stations, but can of course also be installed on walls or top-hat rails.

A special switched-mode power supply ensures maximum efficiency and economic operation: This reduces own consumption to a minimum and the variable input voltage allows universal use of the device anywhere in the world. The innovative electronic load control technology protects the controller against overloading and installation errors.

The Steca TR A501 T has a triac output for speed control that can also be used as a PWM output for controlling a high-efficiency pump. The equipment is rounded off by five inputs for recording temperature and pulses.

Together with an external pulse encoder, the integrated calorimetry system allows the acquisition of numerical information on the solar yields of the system. The clear, graphically animated display provides visualisation of the system and the current operating status. The consistent use of pictograms guarantees easy operation of the controller.

The Steca TR A501 T controller is especially suitable for monitoring and controlling solar thermal systems with a single collector array or simple solar-heated swimming pools. Alternatively, numerous pre-programmed configurations are provided for individual use in other applications, such as back-up heating, solid fuel boilers, thermostats, differencial thermostats / storage tank reloading, return increases and circulation systems.

The Steca TR A501 T also provides important system monitoring and safety functions, such as special error displays for rapid correction of system malfunctions. This ensures long-term, safe and reliable operation of the entire solar system.
