Hello friend,

Welcome to visit us again.

Here we bring up a controller system for replacement to Sundez EVI air to water heat pump in case of maintenance. (2022/12/04)

If your SDDC heat pump has problem in defrosting, please check this DEFROSTING SYSTEM Rev.04-DH2201 (2023/3/15)

In most cases, the sensor failure that installed attached to the  evaporator has created the defrost problem.

So, please try to replace the sensor, here is the specification of sensor 5K – B=3470±1%. (2024/6/4)

If you have any inquires, please feel free to CONTACT US.

Thank you.
