B. STEAM AND HOT WATER HEATED MODELS
The coil solenoid may either be controlled through
the Intelliswitch™ or independently. The Intelliswitch™
is capable of providing the same voltage used for the
motor to power a solenoid up to a 5 amp load on the
call of heat. The heater circuit may be controlled by the
unit mounted sensor, a remote mounted thermostat or
manually through the Intelliswitch™ located on bottom
access cover of the air curtain Piping should be done in
accordance with local codes, regulations and standard
practices. Connect the building system supply and return
to the 1" MPT nipples on the heating coil. See Figure 8.
VII. OPERATING INSTRUCTIONS
A. GENERAL OPERATION
This air curtain comes with a built-in Berner Intelliswitch™
Digital Controller to operate the fan activation, fan speed
selection, and heat activation. The air curtain must be properly
installed before it is used.
1. For detailed instructions on how to operate the
Intelliswitch™ and select from a list of standard modes
of control, proceed to the following pages:
Quick Start Operation Guide, page 9
Frequently Asked Questions (FAQs), page 11
NOTE: For a Detailed Programming Guide, go to
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 Curtain App
NOTE: The air curtain must have been ordered
from the factory with the wi-fi controller to use this
option. The wi-fi controller allows air curtain(s) to
be programmed & operated via smart phone.
Requires on-site, secure wi-fi connection (provided by
others).
Download the "Berner APP" to your smart phone from
the Google Play store. Follow the prompts. Berner
recommends having the on-site user(s) set-up the Berner
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, loosening the nozzle
vane locking screws and adjusting vanes.
