OPERATING SUMMARY
When the timer is at the HOLD position, heat is controlled by the HOLD Thermostat.
When the timer is at any other position, heat is directly controlled by PS-1 (pressure
switch). Note: Both COOK and HOLD Mode heat outputs are directed through PS-1.
It is normal for the Heat Indicator Light to cycle ON and OFF.
The Convection Fan (CFM) is only on during the cooking cycle.
