Control Operation
Control Panel
The controls for the Duke drywell maintain the temperature of the channels. Each channel
has two heat zones. Zones 1 and 2 are in the channel closest to the operator. Zones 3 and
4 are in the channel furthest from the operator. The control monitors each zone’s tempera-
ture and activates a relay to supply power to the heater for that zone. The display will cycle
through the temperature of each zone followed by any fault messages. If the “Up” arrow is
pressed, the system will cycle through the zone temperatures, displaying their actual tem-
peratures. If the “Down” arrow is pressed, the system will cycle through the set point tem-
perature of each zone. The “Heat On” LED will be lit to indicate whether a relay is activated
for the zone being displayed, (No LED – Off; Red – Heat On; Green – Channel Ready). A fault
message will be displayed to indicate any zone that does not reach the set point tempera-
ture within 45 minutes of power up. The default set point is 275 F.
To comply with sanitation requirements, do not set the temperature
control to hold product lower than 170
