Samsung EHS AE040RXEDEG/EU / AE260RNWSEG/EU firmware

Hardware Heatpump
1

Hello,

My setup is made of Samsung EHS AE260RNWSEG/EU paired with AE040RXEDEG/EU.

I was wondering if someone has the firmware for AE040RXEDEG/EU (4kW) and AE060RXEDEG/EU (6kW). I wanted to compare them, see if I could somehow flash the 6kW version to the 4kW.

I believe the hardware is identical and the only difference is in EEPROM.

Also, if someone has a changelog / firmware list for both indoor/outdoor, that would be appreciated as well. For some reason with my current firmware the Waterpump PWM is reported as 2% even when it is off (?).

Outdoor:

Main Micom: DB91-02091B 190704

Inverter1 Micom: DB91-01930A 100007

EEPROM: DB82-04382A 190410

Indoor:

Main Micom: DB91-02103B 2304C8

Thank you,

Nicolae

The best bet is to sign up for the Samsung Business portal and then email them asking for firmware. They don’t seem to update them online any more. I am waiting for the latest to be emailed to me as I want to see if they fixed the hunting issue with the 16 kW R290
