f
The heat circuit will remain energized until the cabinet set temperature is reached
g
When the condensate box is heated to 140 degrees F at the B3probe, 120 VAC is
sent from terminal 5 of connector X12 to the condenser valve (Y1) until the
temperature drops.
h
If the “Crisp and Tasty” mode is selected
•
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.
i
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.
5
With the combi in the Combi mode with time on the timer, the door closed and the
start switch is depressed
a
The front display will include a lighted bar under the Combi symbol
•
When the heat circuit is energized the heat symbol will be energized
•
The cooking mode symbol will be energized.
•
The time display will invert and begin to count down.
b
The fan circuit is energized by the Control Board (A10) transmitting and
receiving a signal from terminals 5,6,7 and 8 on connector X10 to terminals 3,4,5
and 6 of connector X28 on the Gas Board (A20)
c
The Gas board (A20) Transmits a signal from terminal 4 of connector X26 to the
Motor Drive.
•
The motor Drive Board sends a signal through the thermal switch in the motor
from Terminal 5 and receives on terminal 6
•
If the thermal switch is not open the Motor Drive Board (U10) sends 220
VAC 3 phase to the motor.
•
The motor reverses direction every 120 seconds with a 15 second coast.
•
NOTE:
If the set temperature is less than 212 degrees F than fan will be
pulsed on for 2 seconds every 60 seconds after the cabinet set temp (B6).
d
The steam generator heat circuit is energized. Steam production takes precedence
in the Combi mode
•
A signal is sent from terminal 8 of connector X24 on the Gas Board (A20) to
terminal 4 of connector X2 on the Steam Power Burner and Fan Control
(U21) selecting the set speed of the combustion blower.
