OPERATION

General

Heated Zone Merchandisers are setup at the factory for 

energy-saving, automatic operation (Sensors ON operation). 

Refer to “Factory Setpoints” in the SPECIFICATIONS section 

for factory setpoint information. Use the following information 

and procedures to operate a Heated Zone Merchandiser.

WARNING

Read all safety messages in the IMPORTANT SAFETY 

INFORMATION section before operating this equipment.
Do not place food product directly onto hardcoat surface. 

Food product must be wrapped, boxed, or on a food pan.

NOTICE

Do not slide pans across hardcoat surface, use rough-

bottomed pans, or drop anything on hardcoat surface. 

Scratching may occur. Damage to hardcoat surface 

caused by misuse is not covered under warranty.

Theory of Operation

The Heated Zone Merchandiser is designed for efficient and 

environmentally-friendly operation by heating specific “zones” 

only when product is present. The operation of the Heated Zone 

Merchandiser is controlled by a series of optical sensors and 

the LCD controller. The sensors are located along the sides 

of each hardcoat shelf. Larger units have additional sensors 

located in zone dividers that separate each shelf into multiple 

overhead heat zones. 
For all sizes of units, each hardcoat shelf is equipped with 

separate front and rear heating elements. These two elements 

operate independently during Sensors ON operation.
The number of overhead ribbon heating elements is determined 

by the size of the unit. The overhead elements above each 

hardcoat shelf are considered individual heat zones. This 

means that the number of zones on each shelf is either two, 

four, or six—depending on the size of the unit. Each overhead 

element operates independently during Sensors ON operation.

NOTE: Each shelf on a dual shelf Heated Zone Merchandiser 

can be set to a different operating mode.

Sensors ON Operation
At startup in Sensors ON operation, all shelf heating elements 

and overhead heating elements in an empty Heated Zone 

Merchandiser will be in 

Stand-By

. The front and rear shelf 

elements will heat at their 

Stand-By

 power percentage to the 

setpoint temperature. All overhead elements remain off. When 

product is placed on a shelf, the optical sensors signal the LCD 

controller, and the controller activates the appropriate shelf 

elements and overhead elements. Each of the shelf elements 

affected by the placement of product will heat at full wattage 

to the setpoint temperature. Each of the overhead elements 

affected by the placement of product will heat at its setpoint 

power percentage. All affected elements will remain activated 

until all product is removed from the “zone.” Anytime a zone is 

emptied of product, the zone will return to 

Stand-By

.

Sensors OFF Operation
At startup in Sensors OFF operation, all shelf heating elements 

will heat at full wattage to the setpoint temperature, and all 

overhead heating elements will heat at their setpoint power 

percentage. All shelf elements will remain at full wattage and 

all overhead elements will remain at their setpoint power 

percentage the entire time the unit is on.

Lights Only Operation
At startup in Lights Only operation, all shelf heating elements 

and overhead heating elements are disabled. Only the LED 

lights above each shelf will illuminate. This mode provides 

ambient lighting for the display of non-heated product.

Startup

  1.  Move the Power I/O (on/off) switch to the I (on) position.
 

• The LED lights will illuminate.

 

• The LCD controller will startup. After the startup screens 

and during operation, the display will cycle through the 

overhead heat zones showing their current status and 

temperature. 

 • 

Sensors ON = All shelf elements will heat at 

Stand-By 

power percentage to the setpoint temperature. All 

overhead elements remain off.

  

Sensors OFF = All shelf elements will heat at full wattage 

to the setpoint temperature. All overhead elements will 

heat at their setpoint power percentage.

  

Lights Only = All heating elements are disabled—for 

ambient lighting only.

Warning

NOTE: If the warning light comes on at any time, the unit is 

overheating/malfunctioning. Turn off and unplug the 

unit. Contact an Authorized Service Agent or Hatco for 

assistance.

CAUTION

BURN HAZARD: Some exterior surfaces on unit will get 

hot. Use caution when touching these areas.

  2.  When unit is at operating temperature, place pre-heated, 

wrapped food product onto the desired shelf.

 • 

Sensors ON = The optical sensors will signal the LCD 

controller, and the controller will activate the appropriate 

zone(s).

  3. Continue to load and empty the shelves on the unit as 

desired. 

 • 

Sensors ON = The various zones in the unit will adjust 

automatically to the levels of product on the shelves—

ensuring maximum efficiency.

NOTE: To change the shelf setpoint temperature(s), operating 

mode, or the element power percentages, refer to the 

appropriate procedure in this section.

Shutdown

  1.  Move the Power I/O (on/off) switch to the O (off) position. 

All LED lights, heating elements, and the LCD controller 

will shut off.
