The ECtemp 316 is an electronic thermostat with enhanced functionality which can be installed in electric cabinets with DIN rail attachment. The thermostat is used for frost protection on roofs,in gutters, downpipes but also to control room and floor temperature, ventilation, cooling or to the control of snow melting on ground, pipe tracing and similar installations. The main features of the thermostat is temperature range mode,equipped with 2 additional buttons to adjust the hysteresis and the temperature value for levering in economy periods (an external timer must be used). Relay with 2 contact pairs - NO (normally opened) and NC (normally closed), and it is supposed to use termostat for heating and cooling systems. Additionally NO and NC contact pairs are not wetted by a voltage source inside thermostat and can be used for control systems with any voltage up to 250 V. It is designed so that the sensor circuit is galvanically separated from the high voltage part.
