Closing during defrost.Rating: 1 Amp. Max.
Opens during defrost. Rating: 2 HP at 230 Vac Max.
Closed when "Y" is on. Open when "Y" is off.
Provides "off" delay time of 5 min. when "Y" opens.
With DFT closed and "Y" closed, compressor run
time is accumulated. Opening of DFT during
defrost or interval period resets the interval to 0.
