HOT WATER HEATED MODELS
An optional water coil solenoid valve (by others or
Berner) may be controlled through the Intelliswitch™ or
independently. The Intelliswitch™ is capable of providing
the same voltage used for the motor to power a solenoid
load up to 5 amps. This call for heat may be controlled
by an optional remote thermostat or through the built-
in Intelliswitch™ thermostat located on top of the air
curtain. Piping should be done in accordance with local
codes, regulations and standard practices. Connect
the building system to the (3/4"-AE08 or 1"- AE10) MPT
supply and return header connections.
See Figure 8.

A. GENERAL OPERATION
This air curtain comes with a built-in Berner Intelliswitch™
Digital Controller and the Berner AIR™ system (wireless
controller operated by the Berner AIR™ App, downloadable to
smartphone) to control and schedule fan activation, fan speed
selection, and heat activation. The air curtain must be properly
installed before it can be used.
1. For detailed instructions on how to operate the
Intelliswitch™ or to select from a list of standard modes
of control, proceed to the following pages:

www.Berner.com/Intelliswitch
2. Unheated units will have the fans activated by a door
switch or sensor. The unit speed can be selected from
the Intelliswitch™ display.
3. Heated units will have fans activated by a door switch
or sensor, but may also be activated by the thermostat
in Comfort Plus Mode. The unit speed can
be selected from the Intelliswitch display.
4. To operate using the
Berner AIR™ App
, download the
app and follow the prompts. The Berner AIR™ App
allows air curtain(s) to be programmed & operated via
smart phone. Requires on-site, secure wi-fi connection
(provided by others).
Berner recommends having the on-site user(s) set-up
the
Berner AIR™ App
on his/her smart phone.
B. AIR STREAM ADJUSTMENT
1. With the air curtain operating and the door in its full
open position, check to see that nothing is obstructing
the airflow at the discharge nozzle vanes.
2. Find the air stream split location. Hold a handkerchief
by its corners, approximately 12” above the floor. Gently
move the handkerchief back and forth in the doorway.
Make sure the air is being directed to both the inside
and the outside.
See Figure 9.
The split location is
indicated where the handkerchief is vertical with
minimal or no fluttering.
3. The split location should be approximately 3” outside
the doorway. If necessary adjust the discharge nozzle
vanes by de-energizing the unit and firmly pushing/
pulling on the vane tip until properly located.
