General Description

Receiving and Handling

Description

The kitchen fan control center, or KFCC, is a pre-engineered package designed to control the operation of fans in a constant volume kitchen. The package consists of a cabinet encasing one or more fan motor starters interlocked together for on/off operation. Different fan, light and thermal switch combinations may be provided to operate the kitchen hood fan(s), light(s), and heating/cooling capabilities of the supply air. The control center as a standard is equipped with additional relays prewired to the fan starter(s). These additional relays are capable of turning on the kitchen exhaust and shutting down supply regardless of the present state of the fans via integration of a ﬁre system microswitch with factory terminals. The control center can be equipped with temperature interlock, designed to automatically start kitchen fans and keep them running while heat is being generated from the cooking appliances. Hood systems should always be manually started before the cooking equipment is turned on, but if forgotten the interlock will safely trigger the fans to start once heat is detected. Other options are available.

Purpose

The purpose of the KFCC is to provide a complete control center equipped with fan motor starters. The control center provides a common connection point to interlock kitchen exhaust, supply, and hood lights with the hood’s ﬁre suppression system. The cabinet is pre-engineered with terminal blocks for most ﬁeld wiring connections. The control center can also be equipped with interlock between the exhaust fans and cooking equipment, as to meet International Mechanical Code (IMC) 2015 Section 507.1.1. In this case, the system will utilize a temperature sensor in the exhaust duct collar or capture area in the hood to detect heat generated from cooking operations and automatically activate the exhaust fans if not already running.

Product Application

The KFCC is designed for both Type I and Type II (grease and non-grease) constant volume hood systems, where starters are needed to activate fans. The control center can operate both single and three phase fans. Greenheck recommends using one KFCC per hood system (activates all fans simultaneously). When temperature interlock is provided in this package, it is not to be used in conjunction with exhaust ﬁre dampers.

Receiving

Electrical Connections

NOTE

All wiring of electrical equipment must be done to meet NEC and local codes.

NOTE

All field wire must be high temperature rated. All 115VAC field wiring (or higher) must be routed through hard or flex conduit. All low voltage field wiring should be plenum rated if not routed through conduit. Field wiring should not come in contact with the surface of the hood. To reduce the likelihood of electromagnetic disturbance, avoid routing high and low voltage cables in the same cable conduit.

The extent of ﬁeld wiring required will depend on the options and general conﬁguration of the KFCC. Each option is broken out in the next portion of this manual. Each option will either be factory wired or will require ﬁeld wiring. Use 14 AWG, 60°C copper wire unless otherwise speciﬁed.

Power for KFCC

The KFCC needs a power source to operate all inner components. This power source cannot be on a shunt trip breaker; the power must remain constant to the panel, even in the event of a kitchen ﬁre.

NOTE

Do not connect temperature sensors in series. Separate as much as possible the probe and digital input cables from inductive loads and power cables, to avoid any electromagnetic disturbances. Never lay power and probe cables in the same cable conduits (including those for the electrical panel). Loosen every screw and insert the cable end. Next, tighten the screws and gently pull the cables to check their tightness.

Digital Style Temperature Interlock Conﬁguration

NOTE

This section only applicable if the KFCC is configured with digital temperature interlock option.

Pre-programmed, digital temperature controller(s) will be provided to monitor temperatures detected by sensor(s) and engage fan(s).

The fan(s) will start running when a temperature exceeds the set point (defaulted at 90°F) plus differential (defaulted at 25°F). Once the temperature drops back below the set point AND the fan(s) have been running for a minimum run time (defaulted at 5 minutes), the fan(s) will shut off.

Thermostat Style Temperature Interlock Conﬁguration

NOTE

This section only applicable if the KFCC is configured with thermostat style temperature interlock.

Calibration

Thermostat is preset by factory to 95°F (35°C) and has a slow make and break contact. It will make contact on a temperature rise and break contact on temperature fall. The temperature set point may have to be adjusted slightly depending of both ambient and cooking conditions. The adjustment knob is located on the back of the thermostat. Use a small blade screwdriver to make the adjustments.

1. Turn counterclockwise to increase the temperature set point, turn clockwise to decrease the temperature set point.

2. Quarter revolution in either direction corresponds to a 22.5°F (12.5°C) adjustment. Be sure to make small adjustments, about 1/16 of a turn (≈6°F) or less at one time.

3. Do not exceed more than one-half revolution in either direction.

4. Check system operation before making additional adjustments.

Testing

1. Turn the fan switch(es) on, then off to ensure proper fan operation before cooking equipment is started. Once this is veriﬁed, testing can proceed.

2. If applicable, turn the light switch(es) on, then off to ensure proper light operation in the hood. Once this is veriﬁed, testing can proceed.

3. Press and hold down the ﬁre suppression switch connected to the KFCC and verify that the corresponding exhaust and/or supply fan(s) react appropriately when in the ﬁre state. Verify all shunt trip breakers, alarms, and other components utilizing any of the spare relay contacts in the KFCC are activated properly.

4. If the KFCC is conﬁgured with thermostat style

temperature interlock, please follow steps 5 through 9 below. If the KFCC is conﬁgured with digital temperature interlock, please follow steps 10 through 12.

5. For testing only, locate the time delay relay. Turn the time adjustment knob counterclockwise to the ﬁrst mark in order to expedite the testing process. Make a note as to where the timed relay was originally set.

6. Heat up cooking equipment with fans off. Once the temperature reaches the set point of the thermostat the fans will start, preferably within 5 to 10 minutes. If the fans take more than 15 minutes to start, decrease the temperature set point by turning the adjustment screw 1/16 turn clockwise. Do not apply direct ﬂame to the thermostat.

7. If an adjustment was made in Step 6, repeat now.

8. After veriﬁcation of fan start-up, shut down cooking equipment. The fan switch should still be in the off position. Once cooking equipment has cooled, the thermostat will open triggering the timer function in the time delay relay to begin. Once time has expired, the fans will shut down. Thermostat operation can be veriﬁed by checking voltage (115VAC) between terminal blocks T1-B and N1 on the control panel. 115 VAC will be present when the thermostat senses heat.

9. Once proper operation has been veriﬁed, set the dial on the timed relay to its original setting (approximately 20 minute delay).

10. With the fans turned off by the fan switch, turn on at least one piece of cooking equipment under the hood. The fans should automatically start within 5 to 10 minutes. If the fans take more than 15 minutes to start, decrease the temperature set point(s) on the temperature controller (see Digital Style Temperature Interlock Conﬁguration, page 13).

11. If an adjustment was made in Step 10, repeat now.

12. After veriﬁcation of fan start-up, shut down cooking equipment. The fan switch should still be in the off position. Once cooking equipment has cooled below the set point, the fans will shut down.

CAUTION

If provided with temperature interlock, the sensors/ thermostats should never be exposed to direct ﬂame. Exposing a sensor/thermostat to direct ﬂame may render the sensor/thermostat inoperable and will void the warranty.

NOTE

During testing, if the KFCC is conﬁgured with temperature interlock and fans do not start automatically in the ﬁrst 15 minutes of cooking equipment activation, manually start fans to avoid accidental ﬁre system dump due to heat build-up.

Operation

Troubleshooting

1. Turn fans on and off using the fan switch.

2. If KFCC is conﬁgured to control hood lights, turn

hood lights on and off using the light switch.

3. If KFCC is conﬁgured with digital style

temperature interlock, it is normal for the fan(s) to remain running after the switch is turned off. The exhaust temperature controller will shut down fans after heat is no longer present under the hood and the temperature is below the set point. In the event that the cooking equipment is started without turning the fans on manually, the fans will turn on automatically and remain running with the presence of heat under the hood. Once the temperature is below the set point, the fans will shut down.

4. If KFCC is conﬁgured with thermostat style

temperature interlock, it is normal for the fan(s) to remain running after the fan switch is turned off. The exhaust thermostat will open after heat is no longer present under the hood which will activate the timed relay to begin its countdown. Once time has expired, fans will shut down. The timed relay is adjustable from 1-100 minutes. The recommended time delay setting is approximately 20 minutes.

1. Fan(s) do not turn on automatically upon cooking equipment activation

• Conﬁrm that the KFCC has been conﬁgured with temperature interlock, either thermostat style or digital style.

• Check wiring to control panel. With thermostat style interlock, thermostats must be wired in parallel. With digital style interlock, sensors must be wired to the control panel separately.

• Temperature set point is too high, decrease set point.

• No power to fan(s), check breakers/starters/relays.

2. Controller(s) in KFCC display EP1 or EP2 and EP3

fan(s) will not shut off.

• EP1, EP2 and EP3 represent sensor errors.

• Disconnect the sensor from the system, and check resistance between the two wires on the sensor. At room temperature (77°F or 25°C), the sensor should read 1097.4 ohms.

• Check wiring connections between the sensor and control cabinet.

3. Fan(s) do not shut off.

• Fan switch must be in the off position.

• If the KFCC is conﬁgured with digital style temperature interlock, check the controller to determine if there is a sensor error of EP1, EP2 and/ or EP3. If yes, refer to the controller display error message, item2 above.

• Cooking equipment is still hot, and the KFCC is conﬁgured with temperature interlock. Wait for the equipment to cool.

• Temperature set point for temperature interlock is set too low, increase set point.

• Check control circuit (fan starter) wiring.

4. Exhaust fan(s) will not shut off, and supply fan(s)

will not turn on.

• Check hood for ﬁre system dump.

• If no ﬁre system dump has occurred, check ﬁre system wiring between ﬁre system microswitch and control panel.

®

5. Fan(s) do not turn on quick enough.

• Decrease temperature set point

Maintenance

Daily

If KFCC is conﬁgured with temperature interlock, clean thermostat or sensor with cloth and degreaser. Keep clean for best performance; can clean weekly depending upon grease accumulation.

Weekly

Depending on grease production and grease ﬁlter type in the hood, temperature thermostats or sensors can be cleaned weekly.

Seasonal

If KFCC is conﬁgured with temperature interlock, may have to change temperature settings if ambient kitchen temperatures ﬂuctuate between summer and winter seasons.

Frequently Asked Questions Regarding Temperature Interlock

What temperature is the thermostat/temperature interlock set from the factory?

Thermostat style: 95ºF

Digital style: 95ºF set point + 25ºF hysteresis

How do I determine if the KFCC is conﬁgured with thermostat style or digital style temperature interlock?

Thermostat style interlock uses 5/8-inch diameter

sensor(s) mounted in either the hood capture area or exhaust collar(s). The KFCC will include a solidstate relay with a 1-100 minute off-delay dial. Inspect the sensor diameter or look inside the KFCC for this solid-state relay.

Digital style interlock uses 1/4-inch diameter sensor(s)

mounted in either the hood capture area or exhaust collar(s). The KFCC will include a controller with a digital read out, capable of displaying different temperature values. Inspect the sensor diameter or look inside the KFCC for this digital-displaying controller.

Will the temperature interlock automatically start/ stop the fans?

When connected properly to the fan starters the

temperature interlock will automatically control the fans without input from the user. However, the intended use of the temperature interlock is as a back-up to manual control.

With thermostat style interlock, what is the purpose of the timer in the KFCC?

The timer is used to delay the shut down of the fans,

to prevent fan on/off cycling while the temperature in the exhaust duct can reach steady state. Without the delay, cycling could occur both on startup or shutdown of cooking equipment. The delay is typically set at 20minutes.

How many individual breakers does the KFCC require?

The number of individual breakers depends the

number of fans controlled and options included in the KFCC. Each individual fan typically requires its own breaker. The KFCC main power requires its own breaker. Each light circuit is typically put on individual breakers.

Kitchen Fan Control Center

20

Can I still turn my fan on and off?

Yes, the temperature interlock is designed to operate

with a typical on/off switch. The fan may not turn off immediately after turning the fan switch off, it will sense when the cooking operations have cooled and then turn off.
