Your advice on setting up window display controllers is very much needed.
Please tell me how to adjust the controller. I have one defective showcase - +23 on the top shelf, +10 on the bottom, so I realized that I needed a repair and an additional fan. Please, if possible, tell me where I can buy fans for shop windows?
"General idea: - setpoint hold from +12 to +18, taking into account the fact that the temperature in the ianboer.com.au showcase differs from the room by no more than 8-10 degrees - make the delta (differential) in 2 degrees - disable defrosting - set the compressor protection (the interval between inclusions in 3 minutes) Put a home electronic thermometer in the showcase and, after setting up the controller, look at some time (for example during a shift) at the readings of this thermometer by moving it to different places in the showcase."
