[Trivia mode on]

Spectrum TS with 2 evaps.

- Both zones are on cool
- 1st zone shifts to defrost
- 2nd zone goes to "delayed cool"

This means very fast defrost, but what is happening in the system?

Is this "delayed cool" an electric or mechanic feature and what component in a system is actually causing it and why?

[/Trivia mode off]

I think this is easy for you guys :)

suction line check valve on zone in cool will close due to the higher suc pressure coming from zone on defrost,giving delayed cool.

That Q unfortunatly is at the heart of all multi-temp units and should be known off by heart, my way of phrasing it is:-

A box has bad door seals at the chilled rear compartment but a perfect systems. The M/T host which has a frozen load indicates reduced cooling capacity, why?
