hi there folks, was just lookin for some feedback on Mcquay chillers.. recently had call to a site to investigate unit complete shutdown, found that unit had gone over the compressor run hours.. called Mcquay for passwords and basically got fobbed off and they suggested sending one of their engineers to repair the problem for an extortionate fee.. they refused to give me the passwords so i just sat infront of the caravel control panel and started at 0001.. found the password to be 0018 to get into settings and managed to reset the run hours.. was just wandering if anyone else has experienced the not so helpfull "helpline" at mcquay?
