    Dixell control XR06CX question

    Today i was working on a walk in freezer. I noticed the 2 evap fans would run for 1 minute then off for 1 minute. It could continue on that timed sequence. My internet sucked and could not pull up the manual. I figured maybe the control is set wrong. So i attached the manual pdf. I see ther is an option "FS" = fan stop. It says on page 2 under the section for Fans. So i am guessing this is the fan delay setting. Usually a bimetal type fixed at 32 degrees obviously to freeze moisture onto the coil before kicking on the fans. This will make sense after reading the manual. I think the temp was set for 15 degrees or something like that. This will make sense the fans kicks on the supply air raises up to box temp about 28 degrees then boom fans kick off. Coil starts to freeze then fans kick on. I will go back and try to adjust before condeming the control.

    HoHoHo. I just went thru years of having collected Dixell literature and put that literature in numerical order. I am just starting to study this massive amount of info and this seems CRAZY to be considered an advancement in technology and a superior way to control freezer/refrigerators. Some of their controls(and this one) have DOZENS & DOZENS of settings and fault codes which boggle the mind. JHC, who "knows" all of this stuff ?, not me,not yet, I'm just starting. So at the moment I'm just another ignorant fool,but I'm willing to learn , I think, I hope and Pray. LOL.

    So, I guess I'll be looking for some Factory TechSup later today as long as they are available and willing and able to connect with my feeble brain. I'll let you know what I find out. Good Luck to you,and me and everyone else.

    For sure so many setting leaving it universal and able to tweak many different settings.

    I think after reading the manual it makes sense. But Im always open for more information/ confirmation.
    Besides that I am in Miami,Fl. I see your in New York. Hows the coronavirus over there? On the news it looks like New York is by far the most cases. Hope your not in the concentrated area???

    Just this past Sunday I used my 4 year old truck stock of a Dixell Universal 115v control which made me realize my lack of knowledge on these things. Today I had "curb side only delivery" from Sid's of a replacement 115v control and I added a 230v control to my truck stock. Lordy, Lordy have mercy.

    Part # XR60CX-4N1F1-UR(115v)
    Part# XR60CX-5N1F1-UR(230v)

    The FS ( Fan Stop ) setting is a safety feature.
    On a mechanical setup your FDTS ( Fan Delay Termination Switch ) will do the same thing, typically around 55f.
    Your electronic controller which uses thermistors ( one in coil one for ambient ) will sense coil temperature to determine when fans should come on ( coming out of defrost ) or when to shut off ( rise in temperature above setting ).
    Note that the control will shutoff the fans in a defrost mode as well.

    If the control parameters are set properly then I'd be looking for a system problem. Possibly low on refrigerant / starving TEV etc.
    This could cause the coil to not reach a proper temperature and creating the cycling you've witnessed.

    Its more than likely the Fan Delay sensor going bad

    I assume you made sure the sight glass is clear

    Verify the refrigerant charge before you start changing controls

    Maybe I'll take a bike(pedal) ride over to the Weiss/Dixell Factory which is about 2 miles from here in Holtsville,NY. I'll even talk to a Janitor,lol.

    Dixell has a 41 pg "Electronic Control Handbook" from September 2000.

    Can someone justify the cost difference between a Dixell controller over a A12-701 on a refrigerator?
