Features 【Performance Stable】: The measurement temperature is compared with the set temperature through the logical circuit. It is used for conversion contacts for cooling or heating/cooling applications. Dual -septum sensing elements ensure strict temperature control of all loads and applications,and stable performance. 【Smart Settings】: When the relative temperature difference is greater than 1 ° c, the fan or electric valve automatically starts. When the ambient temperature reaches the set temperature, the fan or electric valve is automatically closed. 【Scope of Application】: It is suitable for the temperature control of end -end equipment such as central air -conditioned wind -conditioning machine trays, electric valves, and electric wind valves. It is used for precision temperature control thermal predictors and is suitable for systems with a high heating rate. 【Simple Installation】: Use surface stickers to provide installation screws and convenient installation and disassembly. Safe and easy to use. Open the button, and then turn the knob to set the room temperature. When the built -in air sensor detects the preset temperature, the temperature controller will automatically suspend heating. 【Application Field】: Commercial and civil buildings, providing automatic opening/off control for all gas boilers, circulating pumps, relays, regional valves and other electric heating elements in all heating, refrigeration or heating/refrigeration installation systems. The coil motor and water valve at the end of the central air conditioner. Features: 1.The measurement temperature is compared with the set temperature through the logical circuit.
