Control Options for Model CED

Unheated

* Recommended

*Built-in Time Delay Relay -- Provides a delay for shutting off the air curtain after the door is shut. This is

useful for doors that see a lot of foot traffic, so the unit is not constantly turning on and off during the day.
To be used in conjunction with a door switch.

*Door Switch/Magnetic -- A non-mechanical door switch that turns the air curtain on when the door is
opened.

*High/Off/Low Selector Switch (Remote or Unit Mounted) -- Switches between the high and low
speeds or turns the air curtain off.

to high amp draws according to the National Electric Code, branch fusing can be added so that the unit can
be run from a single power source.

Other Options
