Universal regulator designed to control the temperature in heating systems: - electric heaters, stoves - heating cables, anti-icing systems - incubators, terrariums, aquariums - boilers, heaters, etc. - central heating and hot water pumps - solar collectors - fireplaces with a water jacket - actuators with 2, 3, 4-way valve and for cooling: - refrigerators, freezers, refrigerated counters - fans, coolers - car aggregates (12V or 24V version), etc.
DC-20, short for "double controller", is in fact two temperature REGULATORS placed in one housing with the possibility of any configuration of inputs and outputs and linking both regulators. The device has 2 inputs and 2 control outputs that can operate in HEATING or COOLING mode, and the measurement is taken from the T1 or T2 sensor, or from both sensors at the same time. Thanks to mathematical functions, the measurement from two sensors can be calculated as the difference [T2-T1] (used in systems with a solar collector) or the average [T1+T2]/2.
The regulator can implement both a simple, single or double heating or cooling system as well as a more complex application.
The regulator has a digital temperature readout and the function of calibration of indications. The value from sensor T1 and T2 is displayed alternately every 3 seconds. You can set the controller to display only one reading.
The built-in sounder can be set to signal activation of outputs and alarm states.
The digital input can function as an alarm input or a manual output control mode. It can signal a system failure after the activation of an external pressure switch or STB temperature limiter connected to the digital input. In the event of a failure, it will disconnect the entire system with the ability to maintain the failure state until manually reset by pressing the button.
The regulator is equipped with a high-power relay output 1 20A (maximum resistive load 4500W) and Output 2 with a maximum load of 8A. Mounting in a panel or hermetic, wall-mounted housing.
