The temperature control range is from 0°C to 60°C, perfect for controlling heaters, filter fans, cooling devices and other signal equipment in your home, market and so on. * It has a large data scale and an adjustable button for easy and convenient setting of temperature, and the button colour (red/blue) of the thermostat can be selected for you. * Standard rail clip design, 4 foot brackets, easy to install and disassemble. * Circuit interfaces at the bottom of the thermostat can make the wire connection more stable and safer. * Setting recommendations: The hysteresis (switching difference) of the temperature control should be considered: 7K ± 4K (K= Kelvin) To determine the actual set value of the normally closed contact and switching contact (when used as a normal closed contact), the maximum rated hysteresis should be to the required min. added . Example for Red KTO011 for heating: minimum temperature required in the housing: 5 °C (12 °F) hysteresis of temperature control: +11 K (=7 K ± 4 K) set value at the adjustment button: 16 °C (4 °F) *Applications: the small mechanical temperature regulator small mechanical temperature regulator are used to control electric heaters or cooling fans i n electrical cabinets caused by accidents. Temperature factors. Widely used in communications, wind power generation, fire brigade equipment, ships, petrochemicals, large factories, coastal factories, docks, water treatment equipment, etc. In addition, they can also be used as switching contacts for signal devices as low or high temperature alarms. The adjustment range is 0 to 60. This product has the characteristics of easy installation, small size and long service life. It can automatically start electric heaters and fans, create condensation drops, maintain a good working environment and protect components. It can be attached to DIN rails (DIN15, DIN32, DIN35).
