1st eries Daikin Altherma checker

[Peter_1]

Anyone experience with a logger for the very first serie Altherma's?
This can't be done with a D-checker nor Service Checker but apparently with a RAM checker.
What can be monitored?

depending on the model, you can use the transmission monitor on all units which will show the sensor values, compressor frequency and current and also fan speeds. The 11-16kw low temperature you can use the service checker and plug into the outdoor PCB and select a sky air unit.
