[jriley]

Hi , im an inprover engineer and first time posting in this site so thank you for any advice you give me .
Firstly ive got 3 systems running off one portable controller all playing up doing the same, basically ive got 2 lights on the cassette evaps , one. "elec " and one operation , the units will run for roughly 2 mins then knock off meanwhile all 3 units the "elec " light is flashing , when the units run they work perfect if you get me , i just dont understand why they keep cutting out and why the light is flashing , preasures are fine also


Thanks all
