This WIFI timing temperature controller can realize temperature monitoring, multi-period timing heating or cooling control, and high and low temperature APP push alarm. Adopts linear isolation transformer for power supplys, high wokring performance dual-processor inside, 8-bit MCU for local control, 32-bit MCU for WIFI part, b interference resistance ability, suitable for various harsh industrial occasions, and can ensure the controller is stable and reliable for continue working. Suitable for various commercial and industrial occasions, such as heating and cooling control of HVAC systems, hot water engineering, boilers, breeding, hatching, intelligent electromechanical equipment, etc. Note: The alarm function can only be realized when both the device and the mobilephone are online. Without the network, it is like the mobilephone cannot make a call without a signal.
