An effective humidity shutter and modified water pan grill enable more precise manual adjustment of humidity in an Ovation 28 & 56 Advance and Eco model.
The humidity shutter works by allowing you to control how much steam is allowed to eascape through the pan grill that covers the water trough. The shutter allows you to cover some of the holes on the pan grill meaning less himdity and more accurate control of the humidity within the machine.
On an Ovation Advance simply adjust the shutter to adjust the humidity in the machine according to your requirements and monitor with the digital humidity display.
On an Ovation 28 Eco model there is no built in hygrometer. Simply follow our recommendations or purchase a separate hygrometer.
