Installation
You can mount the ZIP Economizer in any orientation; it is
recommended that you mount it in a position that will allow
full utilization of the LCD and key pad and proper clearance for
installation, servicing, wiring, and removal.
Take the overall dimensions of 6.63" [168.5] x 7.12" [181] x 2"
[50.8]and mount in the interior of the RTU in a convenient location
that you can access. Secure the ZIP utilizing #8 self-tapping screws
(included). A minumum of two tabs need to be secured, one which is
a top tab. Ideally secure all four tabs. Wire the electrical connection
using ¼” female insulated spade connectors to prevent corrosion.

Functions
1. “Monitor Live Conditions” is used to display settings and live values.
2. “Settings” is used to parameterize the ZIP Economizer. Unless otherwise
prompted; default entry is “Auto” or “Off”. (Note: Devices 1 is for CC1,
CC2, EF, IF; Devices 2 is for OAH, RAH)
3. “Present Devices” is used to verify that the ZIP Economizer's Auto Detected
connections are terminated properly. If established I/O is not shown,
verify wiring. If wiring has continuity and device is verified operational
re-enter “Settings” and enable missing device by changing from “Auto” to
“Available” or “Installed”.
4. “Alarms” is used to view current and historical alarms and delete
inadvertently caused alarms.
5. “Service and Commissioning” submenu is used to operate the RTU in
“Manual Mode” or to perform “Acceptance Test”. “Settings” must to be
completed to access.
6. “Status” is a display of the current operating mode. It can be accessed
by pressing ”esc”. The action of pressing any key will drop the user down
from Status to the next level, so repeatedly pressing “esc” will toggle the
display between Status and Monitor Live Conditions. (Note: If status
“Setup Incomplete” is displayed the RTU cooling operation will be
disabled.)
Installation
1. Shut off power to RTU before beginning installation.
2. Note orientation, opening rotation, and spring return rotation of damper
assembly. Mount Actuator to Outside Air and Return Damper assembly.
To ensure tight outside air shutoff; while tightening actuator clamp push
damper closed.
3. Terminate required Inputs and Outputs(I/O): For the ZIP Economizer to
function correctly, the following I/O, at a minimum, are required to be
terminated, wired, and functioning (R, C, Y1, Y2, G, CC1, OAT, SAT, ACT1,
ACT2, ACT3, ACT5). See diagram above.
4. Sensor configuation: The ZIP Economizer automatically detects sensors
attached and automatically configures for single dry bulb, single enthalpy,
differential dry bulb and differential enthalpy.
Settings
“Settings” is the menu displayed when the ZIP Economizer is first powered.
Press “OK” to parameterize required settings. Reference above Keypad Key
definition instructions and navigate as needed.
WARNING Live Electrical Components!
During installation, testing, servicing and troubleshooting of this product, it
may be necessary to work with live electrical components. Have a quali-
fied licensed electrician or other individual who has been properly trained in
handling live electrical components perform these tasks. Failure to follow all
electrical safety precautions when exposed to live electrical
components could result in death or serious injury.

QUICK SETUP
ZIP Economizer Base Module
Required "Settings" Parameters for All Configurations
1. ZIP Code US or Canada (sets the free cooling changeover high limit and
temperature units F/C)
a. When the Zip Code submenu is displayed enter “OK” to begin “US” Zip
Code parameterization. If “Canada” Postal Code is desired press the up/
down arrow to access.
i. Press OK to access digit 1 (flashing) then use the up/down arrow
to parameterize; enter OK when complete. Repeat until all digits
are complete. If a mistake is made press “esc” and repeat from
beginning
ii. When all Zip Code or Postal Code digits are parameterized press
“esc” to move up a level then press the up/down arrow to access
next settings parameter.
2. Vent Min Pos (Outdoor Air Damper Ventilation Minimum Position)
a. When the “Vent Min Pos” submenu is displayed press “OK” to
parameterize (flashing).
b. Use the up/down arrow to parameterize, press “OK” when complete.
The actuator will immediately drive the damper to the minimum position.
3. Additional Parameters may require setting. The ZIP Economizer will auto-
detect added Devices such as a CO2 sensor etc. When the ZIP Economizer
detects a new device, it will prompt the user in the Status level; navigate to
Settings and parameterize blank fields. If the devices are connected upon
first start up their settings will require parameterization then.
4. When all parameters have been set, the ZIP Economizer will show “Setup
Complete” if there are still parameters to set, there will be no action. You
can verify by pushing esc until status level is reached and it will display
“Setup Incomplete”. If this is the case, re-enter settings menu and use up
down arrows to find the parameter with blank fields and parameterize as
described above.
Note: you may enter parametersin any order - eg: Vent min Pos before ZIP
Code - If the RTU is a heat pumpor uses a 2 speed indoor fan, these
paramaters should be enabled first, otherwise the logic may go to Setup
Complete prematurely.
Service and Commissioning (Acceptance Test & Manual Mode)
Setup Complete - Initializing Automatic Mode
1. The ZIP Economizer has built in commissioning processes found in
Acceptance Test. Use “Economizer Test” to verify RTU Integrated
Economizer operation and also if it is known that the actuator stroke is
mechanically limited to less than 90 degree rotation. The test will re-
scale the control signal range to maximum resolution (0-100%) over the
calibrated (reduced) angle.
a. Navigate to the “Service and Commissioning” menu, press “OK”; press
the down arrow to access “Acceptance Test”. Press OK again when
“Economizer Test” appears. Press “OK” again to confirm running test.
Follow prompts during test. This test will open damper to 100% (re-
scale control signal if needed), enable power exhaust fan (if connected),
enable 1st stage of Mechanical Cooling, reverse this process and then
drive to Vent Min Position. When used with a Belimo actuator, the
actuator will speed up to reduce test time. (Note: failure to identify
obstructions or improper setup of damper assembly may result
in an improper scaling and operation of the damper.)
b. This can be done by pressing “OK”... displayed or is automatically
done after 8hrs has passed.
2. Manual Mode is used to override outputs after entering a “Timeout”
duration.
1. When all entries have been completed, the ZIP Economizer will switch to
Status display and show “Setup Complete”, and will immediately show a
“Damper scaling starts in 10secs” and will countdown to 0 (be aware,
at 0 the damper will start to move at high speed) . A message will scroll
saying “Damper scaling for better operation if obstruction is present
rescale damper in commissioning menu”. (For detailed instructions on
this – please see the section “Service and Commissioning” below. This will
open damper to 100% (re-scale control signal if needed). (Note: failure to
identify obstructions or improper setup of damper assembly may result in
an improper scaling and operation of the damper.)
Once scaling is complete, a message will appear saying “Damper scaling
successful”. The ZIP will then show “maximum at 80° = 100%” That
message will show maximum rotation of the damper. This process ensures
the damper is always operating and displayed from 0-100%.
2. Once the message has appeared, the actuator immediately closes the
damper and a countdown begins, until the unit starts to operate in
Automatic Mode (be aware, when countdown complete, the RTU
will respond to thermostat calls which may enable mechanical
cooling).
