• 120 VAC is sent from terminal 6 of connector X12 on the Control Board
(A10) to the Dehumidification Valve (Y2) to pull the humidity out of the
cabinet down the drain.
◊ In the light and medium modes (one and two drops in the display) the Y2
valve will be energized until the bypass probe (B5) is satisfied.
◊ In the full mode (3 drops in the display) the Y2 valve will be energized
continuously.
h When the timer counts to 0 or the core temp probe (B10) reaches the set amount
the cycle ends and the steam generator reverts to the standby temperature of 190
degree F
.
•
i The heat circuit will remain energized until the cabinet set temperature is reached
j When the condensate box is heated to 140 degrees F at the B3 probe, 120 VAC is
sent from terminal 5 of connector X12 to the condenser valve (Y1) until the
temperature drops.
