Afternoon gents,

Reference this site quite a lot, never had a reason to post until now.
Trying to help a colleague of mine.
Our company has inherited a site with 2 x GeoClima chillers GHA-B 2140/66/SP/ECO with the MicroSmart contollers dated 2006.
We are looking for the manufacturers password. We have the user and service codes. The manufacturers password is four digits long, we can't even seem to be able to select the four asterix to enter the password. Have tried holding down set, menu and various button configurations etc. Are we missing something?

Any help would be greatly appreciated

Thanks in advance

Ian

Why you will need manufacturer password? It is for editing software, which is proprietary of GeoClima! In that case, you should contact GeoClima!

we need to access the parameters as the EEV does not appear to close down below 15% and floods the evaporator on low load. We think something is limiting the EEV from closing past 15% within the program as the other chiller closes fully.

Hi N&B.
Are you getting low discharge Superheat as well.
Before condemning the exp valve.
Check your KPA across the evap.
Only poor and low flows will cause liquid to flood back!
Just a thought?
