With high-performance variable-frequency main control chips, the temperature control is precise and stable, with faster response for cooling and heating, and more reliable operation. The full DC variable-frequency drive technology significantly improves energy efficiency, saves electricity and is quiet, making it more economical for long-term use. Multiple safety protection circuits, including overvoltage, overcurrent, overload, and lightning protection, ensure safer and more durable use. The high-precision dual temperature sensing system monitors the room temperature and pipe temperature in real time, maintaining a constant and comfortable temperature without sudden changes. The low-power intelligent standby mode has extremely low energy consumption, does not waste electricity, and is more environmentally friendly and cost-effective for long-term standby., Manufacturer: qxl0403
