the Exhaust and Supply Fan(s), Ultraviolet Lamps (UV), interface with the FP system and/or Building
Management System (BMS). It may also be connected to an Autostart device, Gaylord model “TST”,
in the ventilator to comply with IMC 507.2.1.1. For further information specific to a ventilator it will be
necessary to refer to the appropriate Gaylord “UV” ventilator Technical Manual.

Model Number Description:

The Model Number describes options that may be included
in the Control Cabinet.

CUV-1000

Options:

• “LS” - Includes a Light Switch built-in to cabinet

• “TR” - Includes a Trim Ring around cabinet

• “RM” - Includes a Remote Monitoring Option

• “220V” - Control is designed to be connected to 220VAC

power source

Examples:

• CUV-1000

STARTING THE EXHAUST / SUPPLY FANS AND UV LAMPS

Starting CUV-1000

THE CUV-1000 CAN BE STARTED THROUGH ONE OF THREE OPTIONS:

1. Manually - Press the “F1” (FAN ON) button

2. Autostart - Autostart thermostats in the ventilator activate the CUV-1000

3. Remotely - Remotely start the CUV-1000 from a switch or BMS

*See the following pages for more details on each of these options

Starting the Exhaust/Supply Fan(s) and UV Lamps

To start the Fan(s) press the “F1” (FAN ON) button.

Pressing the “F1” (FAN ON) button will result in:

1. Exhaust Fan On

2. Supply Fan On

3. UV Lamps On

4. Electric Dampers Open (if applicable)

6

STOPPING THE EXHAUST / SUPPLY FANS AND UV LAMPS

Stopping the Exhaust/Supply Fan(s) and UV Lamps

To stop the Fan(s) press the “F2” (FAN OFF) button.

Pressing the “F2” (FAN OFF) button will result in:

1. Exhaust Fan Off

2. Supply Fan Off

3. UV Lamps Off

4. Electric Dampers Closed (if applicable)

Note:

If the ventilator(s) connected to the CUV-1000 are equipped with Autostart thermostats (TST’s), refer to
the Autostart information on the following pages, and the temperature in the ventilator canopy is above
the 90°F, the Exhaust and Supply Fan(s) and UV Lamps will “Autostart” and continue to run until the
temperature in the ventilator canopy cools below 90°F. After the temperature cools below 90°F, the
Exhaust and Supply Fan(s) and UV Lamps will run for 60 minutes, then shut off. Pressing the “F2”
(FAN OFF) button will stop the Fans and UV, but if the temperature is still above 90°F, the Fans and
UV will “Autostart” again.

7

AUTOSTART

Code Requirements:

Some municipalities require the exhaust fan to start automatically whenever cooking operations occur,
to comply with IMC 507.2.1.1. This code requires the exhaust fan to be interlocked with the cooking
equipment such that it will start whenever cooking operations occur. This can be accomplished with
Temperature Sensing Thermostat(s) in the ventilator, Gaylord model “TST”.

Description:

The CUV-1000 is designed to start the Exhaust and Supply Fan(s) automatically when cooking starts,
IF the ventilator it is connected to is equipped with Autostart thermostats, Gaylord model “TST”. The
Autostart thermostats (TST’s) are preset at the factory to 90°F. They may be adjusted in the field, if
necessary.

Operation:

Whenever the temperature in the ventilator canopy is above 90°F, and the CUV-1000 is OFF, the
Exhaust and Supply Fan(s), and UV Lamps will start automatically in “Autostart” mode, and display the
text shown below.

8

AUTOSTART

Automatic Shutdown:

After the temperature in the ventilator canopy drops below 90°F, the CUV-1000 will start to countdown from
60 minutes. After 60 minutes the Exhaust and Supply Fan(s), and UV Lamps will shut off automatically.
Once the countdown has started the Fans and UV can be shut down by pressing the “F2” (FAN OFF)
button. This will cancel the countdown.

Note:

The Fans and UV should typically be
started manually. By pressing the “F1”
(FAN ON) button. The Autostart is
provided as a back-up when the user
forgets to start the Fans (when cooking).
While in “Autostart” mode, pressing the

“F1” (FAN ON) button will put the CUV-
1000 back into a normal “Fan On” mode.

9

REMOTE START

Description:

The CUV-1000 can be started remotely, from a Fan On/Off Switch located elsewhere, or from a Building
Management System (BMS). This is accomplished by connecting terminals “RF1” and “RF2” to a set
of normally open contacts. Please note that terminal “RF1” has 120VAC on it. Refer to the CUV-1000
Internal Wiring diagram for more details.

Operation:

When the CUV-1000 is Remotely Started, the Exhaust and Supply Fan(s), and UV Lamps will start.

Note:

The Fans and UV cannot be shut off at the CUV-1000, if it is running in “Remote Start” mode. They
must be shut off “Remotely”.
