Main functions Mechanical control switch for commercial and civil buildings. It can control the coil motor and water valve at the end of the central air conditioning system for heating and cooling. Multifunctional Central air-conditioning control panel offers multiple working modes and multiple wiring options, including single-line (valve stop and fan not stop) or double-line (valve stop and fan stop). High performance Temperature controller contacts are fully loaded with 220V for more than 100,000 cycles, and the manual switch is more than 60,000 cycles. The constant temperature range is 10-30 C, and the service life is long. Wide application It can control the central air-conditioning terminal coil motor and water valve for heating and cooling. The logic circuit compares the measured temperature with the set temperature. Our central air-conditioning thermostats are used in commercial and civil buildings. Key benefits - Reliable control of heating and cooling at the end of central HVAC systems - Durable components with high cycle life for long service - Flexible wiring options to fit single-line or double-line installations - Precise temperature management within a broad 10-30 C range Use scenarios - Office buildings: maintain comfortable zones with dependable end-of-system control for energy efficiency. - Shopping centers or multi-zone facilities: adapt wiring options to manage different areas with one panel. - Hotels or hospitals: long-life thermostats provide consistent climate control in high-traffic spaces.
