    We install mini-splits and have used Aspen mini pumps. Would like to find an alarm for pump failure. They are set up to be wired to shut down compressor. Any suggestions.

    Most compact one I've seen is ICM340. You need 99% isopropl alcohol to clean aplace to stick the tape, and to clean the probes during maintenance. The bult in time delay eliminates a lot of nuisance trips. The two probes are nice too.
