Universal air to water heat controller Heat pump Auxiliary heating Control board Antifreeze Auto Defrost Water flow warning with sensors Failure action function

The product is designed to control air source heat pump water heaters. The multi-function design supports auxiliary heating function, water flow warning, ventilation pump control, antifreeze function, sensor failure action, auto defrost and timed defrost function, auto restart function, exhaust temperature protection, compressor delay and pressure protection.

Features:

• Multi-function design: with water flow audit, ventilation pump control, sensor failure action function.
• Temperature check: Support check the temperature of all sensors, and the results are displayed for 3 seconds.
• Water temperature setting: support set the temperature, and with the setting ranges of 10℃-70℃, the factory setting is 40℃.
• Two working mode design: There are two working modes of "AUTO" and "SAVE" for you to set. "AUTO" mode: keep heating according to the setting. "SAVE" mode: only heating within three set periods. You can set it according to your needs.
• Multiple control function: Equipped with temperature control, auxiliary electric heater control and water ventilation pump control function.
• Winter antifreeze & auto defrost & timer defrost function: When the outdoor temperature is ≤ 2℃, it will operate antifreeze pumping, the pump runs 3 minutes for every 30 minutes; it will automatically stop when ≥ 3℃.  When the temperature is -9~0℃, it starts defrosting, and when the temperature is 2-30℃, it stops defrosting.
• Multiple protection & warning function: Support exhaust temperature protection function, high pressure and low pressure warning and protection, compressor delay protection and water sensor failure warning.
• Auto Restart & Restore: With auto restart after power off, support for on/off power failure memory function, and support for restore to factory settings.
