Q: What does ITC-308 PT (compressor delay) mean?

A: When the time interval between two refrigeration operation is larger than preset delay, the equipment will start refrigeration immediately; when the time interval between two refrigeration is less than preset delay, the equipment won’t start refrigeration until preset delay is satisfied.

For example, set PT=3. (Compressor Delay 3 minutes)

For the first time, when temperature reached TS+CD, it will turn on the cooling outlet, turn off at TS. It takes 1 minute to reach TS+CD again. At this time, the cooling outlet will not turn on immediately, it will wait 2 minutes.
