The product is designed to control air-source heat pump water heaters. The multi-function design supports auxiliary heating function, waterflow warning, ventilation pump control, antifreeze function, sensors failures action, auto defrost and timer defrost function, auto restart function, exhaustion temperature protections, compressor delay and pressure protections.
with waterflow auditing, ventilation pump control, sensors failures action function.
Support checks the temperature of all sensors, and the results keeps displaying 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 adjust. “AUTO" mode: keep heating according to the setting. "SAVE" mode: only heating within three set periods. You can adjust it to suit your needs.
Multiple Control Function:
Equipped with temperature control, aux electrical heaters control, and water ventilation pump control function.
Winter Antifreezing & Auto Defrost & Timer Defrost Function:
when the outdoor temperature is ≤ 2℃, it will operate anti-freezing pumping, the pump runs 3 minutes for every 30 minutes; it will automatically stop when ≥ 3℃. When the temperature is -9~0℃ starts defrosting, and when the temperature is 2-30℃ stops defrosting.
Multiple Protections & Warning Function:
Support exhaust temperature protections function, high pressure and low pressure warning and protections, compressor delay protections, and water sensors failure warning.
Auto Restart & Restore:
with auto restart after power off, support for on/off power failure memory function, and support for recovery to factory settings.
