• CS704025Z Application Field and Working Principle

  The CS704025Z is a mechanical thermostat used for temperature sensing and regulation in residential or commercial applications. It provides accurate temperature measurements and turns on/off heating/cooling equipment based on user-set thresholds. The use of a mechanical thermostat ensures an efficient and reliable HVAC system.

  The CS704025Z is designed to be used in applications where space is limited and accuracy is important. It is a “mercury-free” mechanical thermostat that uses an “RN35RL” type reed switch and an “M50214” formed metal bimetal element. The thermostat is a “snap action” spring-loaded actuator which provides accurate and consistent regulation of the temperature even in low voltage applications.

  The working principle of the CS704025Z is based on the principle of thermal expansion. The bimetal element consists of two metal strips which are fused together. When the temperature changes, the two metals expand at different rates and the bimetal element bends, thus triggering the reed switch.

  The reed switch is essentially a mercury-free electro-mechanical switch that is triggered when a magnetic field is applied near its contacts. The switch is then connected to the user interface where the user can set their desired temperature set-point. The reed switch is then activated when the temperature reaches the set-point and it triggers the HVAC system to switch on/off.

  The CS704025Z is a reliable and accurate mechanical thermostat that offers accurate temperature measurements. It is ideal for use in residential or commercial buildings and its cost-effective design makes it a popular choice for a range of thermostat applications.
