I put together my DIY STC-100 control box this weekend to use with a True GDM-12 merchandiser.
With the GDM turned all the way up and the STC set at 4.5C, 2 degree variance and 3 minute compressor delay the unit cycles on for 45 seconds every 6 minutes.
I looked up recommended CPH and it sounds like it shouldn't cycle more than 5 times an hour.
When I adjusted the controller to 3 degree variance it cycles on for a little over a minute every 12+ minutes.
I should mention its empty right now except for a couple thawing turkeys. I use a Speidel 30L so I suspect it will hold temp a little better with that much volume, especially since it will be at 60 instead of 40.
3 degree variance with about 5 cycles per hour should be alright, no?
