Solar Controller Compit 971

SOLARCOMP 971 Regulator

The SOLARCOMP 971 regulator is engineered to manage the operation of a solar system efficiently.

Key features of the regulator include:

– Pump control with PWM input, which enables the regulator to control the electronic pump charging the tank smoothly, ensuring economical use of solar energy, and facilitating energy recovery from the solar collector even under unfavorable weather conditions.

– A graphic display that makes operating the regulator easier by allowing users to see which operation mode is active and access system parameters easily.

– A heat meter that calculates the amount of heat collected from the solar collector.

– An electricity consumption counter specifically for pump operation and regulator function.

– Two-stage flow control without needing an additional flow meter.

– Flow meter integration with an input for connecting a pulse generator.

– A built-in clock capable of retaining time for 48 hours in event of a power loss.

– A daily chart documenting the power obtained from the collector.

– Weekly statistics on solar energy gain.

– A signal for gravitational heat lift from the tank.

– Power failure detection along with logging capabilities for the regulator.

– A log that records the last 50 alarm states.

– CW pump control.

– Holiday mode, which protects the system from overheating when hot water is not in use.

– Reverse cooling function to stabilize tank temperature by transferring excess heat through the collector.

– A CWU tank periodic sterilization function that raises the tank's temperature to a preset level once a week to eliminate potential Legionella bacteria.

– Collector freeze protection function, which prevents the solar fluid from freezing by activating the pump when collector temperatures drop below a set level.

– Tank freeze protection function wherein the regulator activates a connected heater or other heat source if tank temperatures fall below 4°C.

– Protective functions include algorithms to safeguard both the collector and tank from overheating.

– The ability to control expanded systems, made possible by additional outputs and sensors.

– A digital interface that allows for monitoring the regulator's operation, utilizing the C14 communication standard.

– Maximum PWM pump performance that can be adjusted for optimal performance.

The set comes with an execution module with a display, three T1001 sensors, and one T1301 sensor.
