Geoclima chiller issue

Hi chaps,

I have a Geoclima TMA 2A450A EC turbomiser chiller on site with an issue.
When it initially fires up, it starts the built in water pump. The pump runs for a minute or so and then turns itself off. A fault code comes up saying no water flow. Now, there is indeed flow, and I've checked the flow switch which works fine, in other words it is indeed sending a signal back to the panel to indicate a flow.

The chiller (on it's own) then does the same again. After this happens a few times it just shuts down.

Trouble is, I can find little to no info on this chiller - even a user manual for the controller. The controller just says Microsmart on it and that's it.

Any help appreciated, or where to find a manual.

Well,

AFAIK, Cooltherm are the main players in the UK for these. Emailed them asking for a service manual etc and no reply!!
Any of you guys had any luck with them??
