COUPLING BOX K

The Euronorm (15) marking at the start of the scale indicates that the control operates starting from +14°C, but the stated control accuracy is achieved only within the actual operating range of +25…+85°C. When the knob is turned to its initial position, the thermostat operates in frost protection mode at an operating temperature of +5°C. The (100) marking indicates an alternative +100°C trigger temperature, with normal triggering occurring at 110°C. (100°C model available on special order). A control center is also required for partial and full standby heating. This product description is an automated translation of the original Finnish description.
