4. OPERATING OF THE DUOTROL™ SYSTEM
Our Duotrol
TM
System is state of
the art technology simplified for
quick and easy operation. The
Duotrol™ System serves two
purposes:
1. ACTS AS A MODE SELECTOR IN RUN MODE
(OFF, CONT & INTER)
•
OFF:
When the selector switch is in the OFF position the ventilation
system will not come on even if there’s a request for ventilation from
any remote controllers.
•
CONT:
When the selector switch is in the CONT position the
ventilation system will exhaust stale indoor air to the outside and will
introduce fresh outdoor air continuously on low speed except when
there is a request for ventilation by one of the remote controllers then
the ventilation system will exchange at high speed.
(Recommended
for maximum indoor air quality.)
•
INTER:
When the selector switch is in the INTER position the
ventilation system will only run on high speed when there is a request
for ventilation. At this time the unit will run on high speed until the
level of humidity is below the set point. The T-3 timer has completed
its time period or once the cycles per hour has completed its cycle.
TIP:
During hot and humid days, it is recommended that you put the
system on INTERM mode. This will reduce the amount of warm and
humid fresh air coming inside the house.
NOTE:
The following controls (EHC1.0, EHC1.5, RD-2, RD-3P, RD-3D, RD-
4P & RD-4D) will override any setting on the Duotrol
TM
all except when in
the OFF position.
2. ACTS AS VARIABLE SPEED SELECTOR
• When the
(+)
button is pushed this will increase the CONT speed of
both ventilation system motors from the previous settings.
• When the
(-)
button is pushed this will decrease the CONT speed of
both ventilation system motors from the previous settings.
NOTE:
When the LED stops blinking the unit is at its maximum high
speed or at its maximum low speed.
IMPORTANT:
If speed setting is too high, extreme dryness can occur
in home during winter months. If speed setting is too high, extreme
humidity levels can occur during hot humid days.
IMPORTANT:
If speed setting is too low, above normal humidity, stale
and contaminated air levels can occur in home.
