Is there a unit that is both hot and cold at the same time?
We have units that can function as both a hot and a cold food well, but none that can function at differing temperatures simultaneously.
Is it temperature controlled?
Yes, all units (with the exception of Iced Food Wells) are temperature controlled. Hot Food Wells feature thermostatic or infinite controls having separate controls for each well. Some cold food wells also have thermostatic controls for each well while others have their interior temperature factory set.
Do I need to put water/ice in the bottom of it?
Generally speaking, filling the water pan is required for hot temperatures. Depending on the unit, ice can be allowed for colder temperatures. Check product’s spec sheet and owner manual to confirm proper operation.
