Heat Zones

A heat zone is determined by the product assigned to a Holding Unit pan. A heat zone is represented with a red dashed outline that appears around a pan or a groups of pans. Heat zone tolerances are determined by the Parent Brand and the equipment manufacturer. The size and configuration of the Holding Unit determines the heat zone range of one or more pans.

When a product is assigned to a pan, the surrounding pans within the heat zone automatically fill with the same product. Products with the same heat zone tolerance may be reassigned to the surrounding pans. An "Out of Heat Range" advisory message appears next to the products that do not have the same heat zone tolerance.

Mirror Option

Use the Mirror Option when a holding unit is accessible from both sides.


Create a view for both the "front" and "back" of the holding unit to allow the kitchen staff to view the holding unit from their point-of-view.

To create a Mirror viewing option:

  1. Create a view that reflects the PHU from the front.

  2. Create another view that reflects the PHU from the front, but select Mirrored.

  3. From the menu list on the left of The Portal, select Sync Changes to Restaurants.

    For more information, see Sync Changes.

When a PHU view is marked as Mirrored, a Mirrored icon appears next to the PHU on the Chef display.
