M.A.R.V.E.L. System Overview
General Description
Halton’s M.A.R.V.E.L. (Model based Automated Regulation of Ventilation Exhaust Levels) system offers
a demand control ventilation (DCV) solution. M.A.R.V.E.L. builds upon the existing Halton product
line, such as the Capture Jet®technology, to deliver a product that reduces energy costs by scheduling
and adjusting exhaust airflow based on hours of operation and appliance use.
Halton has partnered with current energy (CE), a Texas-based international company specializing
in comprehensive energy solutions. By integrating CE’s OEM controls and IRIS™ infrared sensor
technology, Halton’s M.A.R.V.E.L. delivers:
Hood exhaust airflow adjustment depending on cooking activities•
Control of common exhaust fan for minimum energy consumption at all times•
Automatic or on schedule start/ stops•
Automatic balancing dampers•
Early fire warning signals•
Internet monitoring and programming•
M.A.R.V.E.L. Unique Design
Starting with the Halton extensive product line of commercial foodservice ventilation solutions,
M.A.R.V.E.L. adds the following four unique components:
IRIS™ infrared temperature sensors: Used to measure the rate of change of the cooking surface
temperature, the sensor acquires a “heat signature” of the equipment positioned below each sensor.
The thermopile-based device is placed in the ball socket fixture in the Capture Jet®plenum. An air jet
exits the plenum around the sensor to protect the optic sensor from dirt and cooking debris.The sensor
can be easily moved and re-aligned as needed using the provided CE Laser Alignment Tool.
IRISTM Sensor mounted in
Capture Jet®Plenum

M.A.R.V.E.L. Installation Operation & Maintenance Manual
MARVELIO&M/022009/rev1/EN
MC8 Controller: The heart of the system, the controller features 22 inputs/outputs and is designed
to collect real time information and to implement various automation control algorithms. The MC8
Controller responds to the infrared sensor(s) and duct temperature sensor to measure changes in
cooking status.
Example:
Differential Pressure Transducer: Used in conjunction with the value from the temperature sensor and
IR Index to measure and control the airflow thru each hood. In addition, for multiple units with a
common exhaust fan, there is an additional differential pressure transducer mounted on the common
exhaust duct.
Temperature Sensor: Located in the hood collar, the temperature sensor is used in conjunction with
the pressure transducer value and IR Index to control the airflow.

Minimal exhaust flow captures any appliance-generated heat. Default is 60%•
of design air flow or as adjusted to meet requirements.
After idle mode, enters Active mode.•
Active Mode System moves into Active mode when an IRIS™ sensor detects cooking•
activities under the hood.
Exhaust fan speed increased to design air flow and balancing dampers (if•
present) adjusts the airflow in the hood to design level to assure sufficient
capture and containment.
Air flow in the hood is maintained for a predetermined cooking time before•
returning to the Idle mode.
NOTE: If during this time more cooking activities are detected, the cooking
timer will be restarted.
Override Mode Used to override pre programmed operation.•
Two modes:•
Press and hold for 1 second to accelerate the exhaust rate to 100% of the1.
design air flow for a pre programmed period of time (default 5 minutes).

MARVELIO&M/022009/rev1/EN
6. Calibrate and align IRIS™ Sensor
NOTE: The IRIS™ Sensor is calibrated after installation in the hoods.
The sensor is tested using a ‘black body’ (does not reflect IR light) such as a sheet metal with a diameter
of at least 16” (aluminum) and painted black). Always store this calibration tool away from direct sunlight
and where the space temperature can be measured.
The IRIS™ sensor calibration is done in the factory. It has to be done in the field only when the sensor is
replaced.
To calibrate the IRIS™ Sensor, follow these steps:
1. Install the IR sensors in the hood and terminate them.
2. Direct the IR sensors vertically down.
3. Start the control system and launch the Konsole™ software.
4. Bring the calibration tool closer to the sensor (approximately 3-5” from the sensor).
The distance between the sensor and the tool should guarantee the field of view of
the sensor will be completely within the black body surface.
5. Register the space temperature t (in ˚F).
6. Register the IR _Temp reading T (in ˚F).
7. Calculate the calibration offset: Calib_Offset = t – T
8. Assign this value in the Konsole™ screen to the appropriate parameter.
9. Check the IR_Temp reading. The reading should be equal to the hood’s space
temperature reading.
10. Align the IRIS™ sensor(s). See IRIS™ Sensor Alignment (Quarterly or as required),
page 18 for details.
9. Calibrate the Capture Jet®exhaust air flows
Calibrate the Capture Jet®exhaust air flows using the T.A.B.™ (Testing and Balancing Ports).
To determine the correct T.A.B. port reading for the exhaust hoods, follow these steps:
Ensure that the equipment is operating to create a thermal plume prior to the air1.
