Hi-Velocity HE-Z User manual

The Hi-Velocity Systems Zoning Fan Coil features a superior design with simple setup options.
Pre-wired multi-zone controls with adjustable power open and power closed actuators make it easy to
understand and set up our zoning system. The fan coil can also be used with any off-the-shelf 24v
thermostats.
The HE-Z Zoning Package is designed for continuous air circulation when the thermostat is satisfied,
allowing for increased filtration more even air temperatures and fresh-air make-up at all times. Hi-
Velocity Systems sets another high standard and energy efficiency in the residential & light
commercial Forced Air Zoning Industry.
Zoning Controls Features
Adjustable Zone Dampers - Power Open and Power
Closed zone dampers are pre-wired and installed on
the fan coil.
Zone Capacity - The main module controls three
zones using motorized dampers and may be
expanded to 4 or 5 zones.
Compatible Controls - Controls single or two-stage
hydronic heating systems, with single or two stage air
conditioning.
Thermostats - Compatible with off the shelf 24v
Heat/Cool Thermostats. Example (1heat/1cool) or
(2heat/1cool).
Automatic Heat/Cool Changeover - Automatic
changeover from any thermostat allowing for individual
zone comfort.
Status LED - A green STATUS LED pulses as a
steady heart beat to indicate Micro- processor activity
and 24v power is present
System LEDs - Function specific colored LED’s
illuminate to indicate the HVAC system mode of
operation and active zone identification.
Damper LEDs - Green LEDs labelled Zone 1 thru
Zone 5 indicate which dampers are energized to the
open position.
See Page 3
for details.
Constant Fan Control - Any zone can activate the
indoor fan and only the dampers in zones calling for
continuous fan operation will open. Continuous fan
operation will only occur when there are no active or
pending, heat or cool demands.
Internal Fuse (F1)- CAUTION: When the Internal
Fuse is tripped it will get quite hot. To reset the Fuse:
Shut off power to the fan coil and find and repair the
short. Restore the 24VAC power.

Pre-Release 052917

Selecting the Options Using the DIP Switches
Select OAS, if you
want to delay auxiliary heat based on the
outside air temperature sensor. Select TIMER, if
you want to delay staging heat & cool based on
the adjustable on-board timer. NOTE: ‘Y2’ output
defaults to a 30 minute delay, when OAS is
chosen. An optional Outside Air Sensor (OAS) is
required to use the OAS feature.
Select OFF, if you do
not want to inhibit Y2 and/or auxiliary heat
based on the total number of zones calling.
Select ON, if you want to inhibit Y2 and/or
auxiliary heat based on the total number of
zones calling. More than half the total zones
must be calling for the same mode of operation
(heat or cool), or the zone panel will not stage
up. The 50% rule will always dominate the
staging timer and thermostat demands unless
Emergency mode is active.
Select OFF, if you do not
want to use the supply air sensor for the Zone
Control system. Select ON, if you intend to use
an optional supply air sensor (SAS).
NOTE: The indoor
fan mode is automatically set for you. There is
no need to move this switch when setting up for
operations.

Zoning Panel LED’s
The 11 function specific LED’s that indicate HVAC system operation and zone damper status.
Familiarize yourself with the LED functions and definitions, in order to accurately determine the Zoned
HVAC system status and mode of operation.

Continue: Seven Built-in Timers
timers This occurs after any initial power up or
power failure. Press the Reset button for 1
second to override.
Short Cycle Timer - When all zone demands
are satisfied, the panel will not resume the same
mode of operation for a minimum of 3 minutes.
Changeover Timer - Prevents the system from
rapidly switching between heating and cooling
modes. At the end of a call, a 4 minute timer is
started and the panel will not switch to the
opposing mode until the timer has expired.
Opposing Call Delay - A 20 minute delay must
expire, or the active zone(s) must satisfy, before
the panel will honor a demand to changeover to
the opposite mode of system operation.
Staging Timer/OAS - The STAGING TIMER
sets the amount of continuous call time in 1st
stage, before second stage heat or cool is
energized. NOTE: The potentiometer also
serves as the Outside Air Changeover Setting.
Purge Delay - The STAGING TIMER sets the
amount of continuous call time in 1st stage,
before second stage heat or cool is energized.
NOTE: The potentiometer also serves as the

The OAS LED illuminates solid to
indicate that the Outdoor Temperature

The OAS LED will blink rapidly to
indicate a shorted or open Outdoor Air
Sensor circuit.
The SAS LED illuminates solid to
indicate that the Supply Temperature
has exceeded the chosen set point on
either the HIGH TEMP LIMIT or the
LOW TEMP LIMIT. The SAS LED will
blink rapidly to indicate a shorted or

Series Fan Coils. Order HE-Z fan coil unit from our Standard Price List and add these multi-outlet
tops to your order as a separate part.
The plenum take-off outlets are 7" in height and adds to the height of the 32" fan coil. The fan coil can
be installed in the high boy, counter flow or horizontal position. When you are designing the individual
zones try to design each zone to have equal amount of vents and load.

Constant Fan Comfort
Having the fan switch at the thermostat to the
“ON” position is strongly recommended. This
utilizes continuous air circulation for optimal
Indoor Air Quality (IAQ) and Energy Efficiency.
Independent testing has shown that utilizing the
recirculating fan with the Hi-Velocity Systems
VFD motor reduces total energy usage. This is
due to less on/off cycling of AC and Heating
equipment by constant de-stratification of the air.
The zone controller board will default the
actuators in the open position when there is no
call for constant fan, heat or cooling. If one of the
zones is calling for constant fan and the others
are not, the zones that are not calling will close.
In the event of a zone calling for heat or cooling
the zone dampers (regardless if a zone is calling
for constant fan) will close the non-calling
heat/cool zones. The actuators have been pre-
adjusted with approximately 10% bleed through,
this allows for air to circulate in a non-calling
zone. With the 10% by-pass it will not over heat
or cool a non-calling zone if the other zones are
calling heat or cooling but will add comfort as the
air will not be stagnate in the non-calling zone
and will supply more even air temperatures
throughout.
Zone Dampers Adjustment Stops
The Adjustment Stops on the
actuators have been preadjusted with
approximately 10% bleed through.
This allows for air to circulate in a
non-calling zone. This can be
adjusted by adjusting the “0" stop
limit.
Balancing Zones
In the case that there is too much
pressure through a calling zone
(usually a smaller zone on the
system) the damper can be adjusted
partially closed. Partially closing a
damper will cause back pressure on
the blowers pressure control and the
fan coil will slow down the motor.
Adjust the “1" stop to limit the
actuators opening to the level of
pressure/air required for the air flow
desired for the smaller zone.
Zone damper Wiring
The zone dampers on the HE-Z
Zoning Fan Coil comes pre-wired.
There are Seven Built-in Timers that
over ride the operation of the zone
dampers and output signals of the
zone board these are shown on
pages 2 and 3.

NOTES:
1) USE THERMOSTAT FAN SWITCH TO DISABLE/ENABLE CONTINUOUS FAN.
2) ‘C’ TERMINAL ON THERMOSTAT (COMMON) IS NOT NEEDED FOR SOME
THERMOSTATS CONSULT THERMOSTAT INSTRUCTIONS FOR DETAILS.
3) W1 AND W2 ACTIVATES AUXILIARY RELAY (A3) ON CALL AND CAN BE USED
WITH A1 AND/OR A2 AS DRY CONTACTS, ARMED 24VAC FROM THE ‘R’
TERMINAL, OR ARMED 110v FROM THE ‘L’ TERMINAL.
4) AUXILIARY HEATING RELAY TIMER ACTIVATES CIRCUIT FOR 5 MINUTES
EVERY 24 HOURS STARTING WHEN POWER IS APPLIED TO THE UNIT.
5) LED 1: INDICATOR LIGHT FOR FAN SPEED OPERATION AND AUXILIARY
RELAY OPERATION. SEE BELOW FOR LIGHT OPERATION SEQUENCE.
6) SEE INSTALLATION MANUAL FOR MORE DETAILED WIRING DIAGRAMS.
7)
8) FAILURE TO SET PROPER AIR FLOW AND/OR OPERATION OF THE SYSTEM
MAY RESULT IN DAMAGE TO EQUIPMENT.
9) FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY BEFORE
INSTALLATION COULD CAUSE PERSONAL INJURY AND/OR PROPERTY
DAMAGE.
10) ENSURE THAT THE FILTER IS KEPT CLEAN AT ALL TIMES.
11) MOTOR HAS PERMANENT LUBE BEARINGS AND DOES NOT REQUIRE
OILING.
12) WARRANTY VOID IF FAN COIL UNIT IS USED DURING CONSTRUCTION.
FOR SINGLE STAGE COOLING OPERATION USE Y2, OTHERWISE THE FREEZE
STAT WILL BE BYPASSED.
