Intended use and description of the controller

The QC-PC-PID-01 is used for temperature control of objects using Peltier technology.

The controller detects the temperature of the object to be tempered via a PT1000 sensor and controls the Peltier element with a continuously regulated DC voltage.

The control can optionally be set to a P, PI, PD or PID behavior.

The controller is operated and set using the integrated touchscreen. The user interface is embedded in a menu structure.

The controller may only be used up to a maximum current of 8A.


Short note & useful information:
In order for the controller to work, it is imperative to connect the Peltier element correctly. If the Peltier element is poled incorrectly, uncontrolled high or low temperatures will occur during operation. Quick Ohm Peltier elements have their electrical connections on the "warm side" of the Peltier element. If you direct the connecting wires towards the viewer with the red wire to the right, the "cold side" is at the top. The object to be tempered must be thermally coupled to the cold side. The lower side must be thermally coupled to a heat sink. This side is called the "warm side". If a voltage is applied to the connections, the cold side becomes cold when the voltage on the red line is electrically positive compared to the voltage on the black line. With modules other than Quick Ohm Peltier elements, it is imperative to check this relationship. Depending on the description, these modules may have to be connected the other way round.

Caution: A Peltier element may only be supplied with electricity if it is in contact with a sufficiently large heat sink. Otherwise the module will overheat and be irreparably destroyed within a few seconds. The surfaces that are contacted with the Peltier element must have good planicity. For a good thermal connection, the contact surfaces should also be filled with thermal paste, thermal oil or thermal foil.

Before switching on, the contents of the operating instructions must be carefully studied and understood. The controller may only be connected to a professional installation. Before switching on, make sure that the maximum permissible current of 8 amperes cannot be exceeded. The data sheet of the Peltier element must be consulted for this. Please read these instructions carefully. The menu is explained below. This is followed by a description of a step-by-step commissioning.
