I have a RB ESP Modular controller with 8 zones. Recently I have had a problem with zones running when there is zero time programmed for the zone. For example, last night I set a program to run zones 1,2 & 4 starting at 5 o'clock this morning. Those zones ran correctly but when zone 4 finished, zone 5 started. I spun the dial to zone 5 and the time to run read zero. This controller is capable of using 4 start times per program but I verified that only the 1st start time was set...the others read 00. Last week a similar thing happened. I set zones 5 thru 8 to run, which they did, but when zone 8 finished zone 1 started. When I checked the controller zones 1 thru 4 had zero time. I installed this controller back in January and it has worked great up until now. Has anyone seen this sort of thing before?
