Hi All,

A little help needed please......I have a 3 unit system running off one controller, not sure on models at moment. If the controller is switched on the whole system shuts off after 1hr. There is NO timer set.
One thing I did notice is that the controller even if set at full fan and louvers on swing, after 5mins of running reverts to half speed fan and louvers pointing down and that a message is then seen in the controller saying, 1hr ONLY.

Any help very much appreciated.

Thanks All

mr slims-if it shows 1hr only, hi condensate will cut it out - pull the drain plug check how much water u get out of each unit. p6 freeze protection and p5 drain probs are common,as well as the infamous p8 outdoor issues, bit more info would be helpfull

Sorry for lack of details but no codes show on controller, literally just goes off. I am back at site tomorrow with podium to gain access to indoor and outdoor units. So if I dont get it working then at least I may have more info.

Thanks for reply :)

if no fault code then check for external pumps with failsafes wired in on cn33
