I do heating and ac for residential.. I would like to switch over to refrigeration. Do you have any advice on how i should start? Thanks Love the video!!
I have same control for my meat case. Its not keeping the temp between 35-40 in meat case. Even at night time when curtains are closed. Its freezing up. What could be the problem here sir?
@minesh I’d definitely check to make sure the settings on the digital controller are accurate(35 set point, 4 or 5 degree diff). You’ll also need to check to see if you have a defrost control and that it’s set properly and actively working. Ensure that your crew is closing the door after entering/exiting. If those check out then you’ll have to check the condenser and make sure it’s not low on refrigerant. Those are the basic items. It could be a number of other items but at that point I’d recommend having a service company identify the problem as they would need special tools to diagnose.
Gus Garcia thank you for your response. This is Brand New meat case only a year old. Its 3 cases connected to eachother approximately 32ft long. Right now i am having issue where 1 case is at 35, 2nd is at 27, and 3rd is staying at 20. I am not understanding whats causing it even the cooler service guy having hard time figuring out.
Wow, where is the thermostat sensor located? Supply air, return air or in the coil? And did this issue just start or have there been problems all along? The tech will need to check all fans and ensure nothing is blocking air flow. They’ll also need to check superheat on the TEV’s. If all checks out then they would need to install solenoids and separate thermostats for each case. These recommendations are vary vague as I haven’t had eyes on the unit.
Thanks , your video reminded me to program it, haven’t installed one in 6 years and forgot 🤣

Hi Gus. Thank you for posting this very informative video. The manual is not very clear in how to change the settings to Celsius. Can you help?
