only heating within three set periods. You can adjust it to suit your needs.

Multiple Control Function: Equipped with tempeure control, aux electrical s control, and water ventilation pump control function.

Winter Antizing & Auto Defrost & Timer Defrost Function: when the outdoor tempeure is ≤ 2℃, it will opee anti-zing pumping, the pump runs 3 minutes for every 30 minutes; it will automatically stop when ≥ 3℃. When the tempeure is 9~0℃ starts defrosting, and when the tempeure is 2-30℃ stops defrosting.

Multiple Protections & Warning Function: Support exhaust tempeure 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.
