johnson controls on walk in freezer

[andyc425]

Client complaint ice on the floor in walking freezer, got to site Frozen droplets on ceiling and ice on floor defrost cycle obviously condensing and dripping onto floor, what I want to do is check the defrost intervals, temperature termination setpoint etc to identify problem but I cannot find how to access parameters no where anybody know
It's a cr-nt150-1 module

oh lower your defrost termination temp and have a 1-2 min drain time/dripping time, also dont start your evap fan till the evap coil is about 5 deg

thanks for the reply, I already have this manual but it does not actually tell me how to actually access the parameters im at a dead end until I can do that

throw it into the bin and put a dixel/carel or the like onto it.

they are a mega pita to navigate and get into and even harder to explain to someone over the phone compared to others.
