AC update questions (bear with me)

No digital panel, all mechanical. The unit is right forward in the engine room just aft of the fuel tanks.
It’s only just perceptible in the bow cabin but very noticeable in the twin guest cabins port/stbd

Take a look when it is running.

They are big mechanical devices and you may find tightening things up or a rubber pad will stop a lot of the noise

I see. Can you remind me when Seralia was built, J?
The digital panel for cabins thermostats is something relatively new in Condaria systems (early naughties, IIRC), but I would have sworn that it was used for chillers much earlier...

I stumbled on a spec difference which is puzzling me.
For my old thermostat, the webpage I previously linked specifies:
"1 potential-free changeover contact output: 10(2)A / 250V"
While the newer one shows:
"1 potential-free changeover contact output: 5(3)A / 250V"

Now, WTF does the difference which I highlighted in bold mean?

Jusr in case anyone might be interested, I found the answer to my doubt above.
The first number (10 vs. 5) refers to the max resistive load, while the one in brackets is for inductive loads.
In simpler terms, the newer thermostat can handle up to 3A when connected to fancoils, vs. 2A of the original one.
Result!

Sorry, I can't answer your question P, but if you end up buying them, maybe I can join to make a bigger order as I would like to replace mine at some point (5 or 6 I think)

Hi M, the best price I found online for these thermostats is €28.7+VAT.
I got in touch with the supplier, who offered €21+VAT for 4 or more units, plus €15 shipment - which I suppose would apply to each address in case of an order split into different locations.
Just drop me a pm or email if you are interested. Same goes for anyone else interested, of course.
