After setting the upper and lower limits are automatically adjusted, for example, if the setting is 100 degrees, it will be 100 degrees as the standard, the positive and negative difference is 1 degree, the heating is lower than 99 degrees, and the cooling is higher than 101 degrees, for example, the required temperature is 50 degrees Celsius, high temperature is 51 degrees Celsius, and the low temperature is 19 degrees Celsius, which can make sure that your 50 degrees is constant.
Setting and wiring method:
1, if 220 coil equipment control with contactor: as long as the thermostat working power of the l wire stakes lead to the stakes on the normally open stakes for the thermostat control, and the other catch stakes device is used to control one end of the contactor coil. The other end of the device contactor coil is connected to the N wire.
2, 380V coil equipment control with contactor: the thermostat working power L wire stakes on a wire lead to the thermostat control on one end of the normally open pile, thermostat control on the other end of the normally open pile and equipment contactor coil is connected to one end of the contactor coil of the equipment, the other end of the contactor coil of the equipment will be connected to the three-phase power supply of the B-phase.
Expanded Information:
1. If the thermostat is used under the following conditions, such as nuclear power control, medical equipment, automobiles, trains, airplanes, aviation, recreational or safety devices, it is necessary to install a safety protection device or to contact the thermostat manufacturer for information, otherwise it may cause serious damage, fire or personal injury.
2. Do not touch the terminals while the thermostat is energized or you may be electrocuted.
3. Do not remove or replace the thermostat. If necessary, contact the thermostat manufacturer, or electric shock or fire may result.
4.When connecting the power cord or signal input, check the terminal number or it may cause the thermostat to burn out or catch fire.
5, The thermostat can not be used outdoors, otherwise it will shorten the life of the thermostat or electric shock accident.
6, the temperature controller should be avoided in flammable, explosive, humid, heat radiation, severe vibration and other places, otherwise it may lead to the temperature controller can not work properly.
7, the thermostat should not have dust or sediment, otherwise it may lead to electrical failure or fire.
8, do not use gasoline or chemical solvents to clean the thermostat shell. The use of these solvents will damage the instrument housing. Use a soft, damp cloth to clean the plastic housing.
9, when the thermostat adopts the internal automatic compensation method, the compensation line should be connected directly to the terminal on the back cover of the thermostat, and the middle part should not be converted to a common line, otherwise it will produce measurement errors.
10, when the thermostat control output for the relay contact, it is recommended to use the intermediate relay, and then use the intermediate relay contact to control the contactor, so as to extend the service life of the built-in instrument relay, but also isolate the isolator inductive load on the interference of the instrument, is very conducive to ensuring that the temperature control system for long-term reliable and safe operation.
