4 With DFT closed and “Y” closed, compressor run time is
accumulated. Opening of DFT during defrost or interval
period resets the interval to 0.
Defrost Board Operation:
Closes 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.
