Hi ... I am asking for help for configuration of various brands of precision ac ... I want to ask is how do I change the auto settings for ac precision over which different brands and types, for example between the Liebert-hirros-citec-RC, is it possible to be combined? what devices can be used ?.....

If they have the same microprocessor or at least they have the same signal logic management, yes, but I'm prone to think that each brand has their own control logic for changeover, and therefore it is most probably difficult if not impossible.

Hi Nick ..... if the air conditioning unit listed should use the R407 refrigerant but we fill these units with the R22 is there a problem?Because most customers complain about the price of R407 which is very expensive ....

Off topic here, but the answer to your question is yes. Sorry for your customer, but if you repair the leaks, they will not have to pay for R407c anymore.

Hi Eep,

You could probably operate/control the units, remote on/off, timer, change over on fault condition etc. via a trend controller (e.g. IQ3), all depends on what inputs and outputs the units controllers can support.
