Required "Settings" Parameters for All Confi gurations
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 entered 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 fi elds. If the
devices are connected upon fi rst 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 fi nd the parameter with
blank fi elds and parameterize as described above.
Note:
you may enter parameters in any order - eg: Vent min Pos before
ZIP Code - If the RTU is a heat pump or uses a 2 speed indoor fan, these
paramaters should be enabled fi rst, otherwise the logic may go to Setup
Complete prematurely.
Service and Commissioning (Manual Override 1 &2)
Setup Complete - Initializing Automatic Mode
The ZIP Economizer has built in commissioning processes found in
"Manual Override1 - Devices" & "Manual Override2- Forced Modes".
1.
Devices.
Use “Manual Override1- Devices” to verify RTU integrated
components in manual operation. Navigate to “Services and
Commissioning” menu, press “OK”; press the down arrow to access
“Manual Override1- Devices”. Press “ok” again to select a desired
“Timeout” duration. Press down arrow for selectable devices. The
device options are “Damper Pos”, “Compressor 1”, “Compressor 2”,
“Exhaust Fan”, and “Fan Speed”. Devices will only appear if they are
connected. Return to automatic for normal functioning of the ZIP
Economizer.
2.
Forced Modes.
Use “Manual Override2- Forced Modes” to override
outputs. Navigate to “Service and Commissioning menu, press “OK”;
press the down arrow twice to access “Manual Override2- Forced
Modes”. Press “ok” again to select a desired “Timeout” duration”.
The forced mode options are “Free Cooling”, “Integrated Cooling”,
“Mechanical Cooling”, “DCV”, and “Unoccupied”. Depending on the
mode (see “Menu Sequence” section for notes), there will be the
option to change or simulate the following: Y1 and Y2 stages, “OAT
simulation”, “SAT Simulation”, “Fan Speed”, and “C02 Simulation.
Selections will appear depending on what devices are connected.
Return to automatic for normal functionality of the ZIP Economizer.
3.
Damper Scaling.
The test will re-scale the control signal range to
maximum resolution (0...100%) over the calibrated (reduced) angle.
When using 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.)
Additional manual overrides can be found later in this document.
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).
