•  If the bypass probe (B5) drops below the set level the steam circuit will start 

again. 

e

  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. 

f

  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. 

g

  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. 

7

  With the combi in the Rethermalization 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 Retherm 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

  Hot air heat circuit is energized 

•  A signal is sent from terminal 8 of connector X15 on the Control Board (A10) 

to terminal 4 of connector X2 on the Hot Air Power Burner and Fan Control 
(U20) selecting the set speed of the combustion blower. 
◊

  When this speed is attained the signal is sent from terminal 2 of connector 

X2 on the Hot Air Power Burner and Fan Control (U20) to terminal 2 of 
connector X15 on the Control Board (A10) 

•  A request for heat is sent from terminal 3 of connector X12 on the Control 

Board (A10) to terminal 10 on connector X1 on the Hot Air Control Module 
(N20) 
◊

  24 VAC is sent from terminal 2 of connector X2 on the Hot Air Control 

Module (N20) to the hot surface igniter (R20).
