Electrical Connections

Electrical Connections

1.Run two 18 awg thermostat wire from each temperature sensor to the appropriate electrical circuit connections. (See Step 3 for connection options).

2.In junction box, connect leads on RTD to the 18 awg conductors using appropriate size wire nuts.

•Wires are interchangeable with one another.

3.Choose the final connection based on:

•Terminals T3, T4, T5, T6, T7, T8 (if applicable) in fan control center (KFCC).

•Terminals 9, 10, 11, 12, 13, 14, 15, 16, 17, 18 (if applicable) in control box on top of hood/utility cabinet.

CAUTION

Do not connect temperature sensor in series with fan power. This will result in damage to the temperature sensor and will require replacement.

Breaker Panel to Control Box or Fan Control Center

1.Connect a Single Pole Single Throw (SPST) switch to one of the following based on application:

•Terminals 3 & 4 in the control box.

•Terminals S1 & S1H in the fan control center.

Circuit Connections

1.Standard Interlock Control

•120V, 10 or 15 amp circuit to terminals 1 & 2

•Control voltage for fan starter activation

–120V, 24V or other control circuit (drawing on page 5)

•Control circuit power to terminal 7

•Terminal 8 to fan starter coils

•Terminals 7 & 8 to fan starter coils

2.Fan Control Center Integration (KFCC)

•Power to H1 & N1 in fan control center

•No additional control circuits are required fan starters are factory wired

Calibration

The temperature controller is preset by the factory to turn the fans on at 95°F. This is controlled by the set point on the temperature controller. The temperature set point may have to be adjusted slightly depending on both ambient and cooking conditions. The adjustment is made through the buttons on

the temperature controller. To adjust, follow these instructions:

1.Press the SET button to see the set point.

2.Press the UP/DOWN arrow button to change the set point.

3.Press the SET button to view the current temperature.

4.Check system operation before making additional adjustments.
