Setting the Humidity:

1. At any time, press the knob and the setpoint %RH will

ash.

2. Turn the knob to the value you desire.

3. Press the knob to set the value.

For use with the Retherm Control:

1. On the Retherm control, when selecting the COOK

temperature, the humidity setpoint will be ashing on

the Aquatemp control.

2. Turn the knob on the humidity control to the desired “Cook Humidity” value.

3. On the Retherm control, when selecting the HOLD temperature setpoint, the humidity setpoint will be

ashing on the Aquatemp control.

4. Turn the knob on the humidity control to the desired “Hold Humidity” value.

NOTE: These humidity values then are set and switch

automatically based upon which Retherm mode it is in.

How to use the Automatic Water Fill:

There is a water ll connection under the bottom left rear

of the oven. Remove the plug on the end of the connector.

1. Connect the plastic tubing provided to the connector and the other end to your water supply. Turn water supply on.

2. Press and hold both the DISPLAY button and the knob

of the AquaTemp humidity control for ve seconds.

3. Turn the knob until when the display shows FILL, select “Y” for yes and press the knob to set.

4. Go to END to exit the menu. Auto water ll should start.

To shut down:

1. Press and hold both the DISPLAY button and the knob of the Aquatemp humidity control.

2. Turn the knob to FILL and push to enter. Select “N”

for no; go to END to exit the menu.

3. Turn off your water supply and clean out the water pan after it cools (See “Maintenance Instructions” on page 8).

NOTES: It is recommended to use treated water to

prevent failure of ll valve.

If water supply pressure is high, it is recommended to

regulate it to make sure the ll valve closes reliably.

The DISPLAY BUTTON momentarily shows the approximate relative humidity in the oven. When water level is low, %RH is not correct, so no value is displayed and the water heater does not heat.
