Open and Closed Adjustment Stops
The
Adjustment Stops
can be
adjusted to stop rotating before it
reaches its stops. These can be
moved to any position without harm.
1. Loosen the end stops.
Caution: be
cautious not to unscrew from the
captive nut under the slot.
2. Move the stops (2.5° steps) to the
desired position and re-tighten the
screw.
Manual Override Button
Press the
Manual Override Button
and the gear train is dis-engaged so
the damper shaft can be moved
manually. Release the button and the
gear train is re-engaged.
To lock in manual mode press down
the Manual Override Button and push
in the side locking tab. To release,
push down the Manual Override
Button and release this will disengage
lock.

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.
