SECTION 9
Adjusting Fan Speed for Balancing and Capacity Requirements
For high-speed adjustment/balancing, use any means to initiate high speed (e.g. ES-M1, R—Hi
jumper wire, or engage 24V R—Hi control), then:
1. Press and hold either the FRESH air or
EXHAUST air push buttons (not both) for 3
Seconds to initiate SPEED ADJUST MODE.
2. Press the corresponding button to adjust
the fresh air fan or the exhaust fan speed,
thereby changing the air flow. Each press
reduces motor speed until the default
minimum is reached, at which point
the motor will return to its peak speed.
Allowing a brief pause between presses
(about 0.5 seconds), you will press the
adjust button about 70 times before
reaching minimum speed. During the balancing procedure, you can switch between
adjusting the fresh air motor or exhaust air motor.
3. To exit balancing/speed adjust mode, stop pressing buttons for 10 seconds. This will place
the unit back in operating mode with the new speeds saved to the circuit board’s memory.
Low-Speed Adjustment/Balancing. If low speed adjustment is desired, use a jumper wire (R—
Lo) or remote control to put the unit into low speed and follow steps 1-3.
SECTION 10
Installing the Wall Control
Your unit includes a model RVC8 wall control. Your unit can also accommodate other 24 VAC
controls and can be connected in Series or Parallel.
CAUTION:
IF INSTALLING OTHER 24 VAC CONTROLS FOLLOW
ALL INSTRUCTIONS INCLUDED WITH THE CONTROL AS WELL AS ANY
LOCAL OR NATIONAL CODES THAT MAY APPLY.
CAUTION:
FOR UNITS WITHOUT A RECIRCULATION DAMPER, TURN OFF
RECIRCULATION FUNCTIONS IN CUSTOM SETTINGS.
WARNING:
ROUTE CONTROL WIRING ACCORDING TO LOCAL
BUILDING CODES.
Mounting the Control
1. Mount in a central location within the building.
2. Fits a standard 2" x 3" (nominal) electrical wall box (not
included). While your wall control comes with a screwless face
plate, you can substitute it with another to match any décor by
using a flat screwdriver to pry off the original face plate and by
removing the 5 mm screws securing the faceplate base.
3. Drywall anchors may be used where a wall box is not available.
Wiring
1. Using a 3 mm flat head screwdriver, connect 4-conductor wire
to the 12 VDC (4-wire) removable terminal block provided.
Wiring the controls involves simply matching
terminals on the control to those of the ERV/HRV
terminal block (see right).
WARNING:
DO NOT
CROSS THE +12V/12 AND GROUND
(GND/G) WIRES. FOR RVC8 CONTROLS, DOING SO
WITH POWER CONNECTED TO THE ERV/HRV MIGHT
DAMAGE THE WALL CONTROL PROCESSOR.
USING THE CONTROLLER
Backlight
Press any key to turn on the backlight. The backlight will remain
illuminated for 10 seconds after the last button is pushed.
Power
Use this key as a quick means to turn the ventilator off.
Mode
Use this button to enter the mode selection menu and to activate
a chosen mode of operation.
Timer
Use this button to activate the ventilator into high speed for 20,
40 or 60 minutes. The timer button can also be used to turn off
the high speed timer function.
Down Arrow
Use this button to decrease desired humidity setting, or to scroll through menu options.
Up Arrow
Use this button to increase desired humidity setting, or to scroll through menu options.
Fresh air
adjust button
Exhaust air
adjust button
SELECTING A MODE OF OPERATION
Press the mode button and you will see that the current mode icon
and mode number (00-06) will flash. Use the arrow buttons to scroll
up and down the numbered menu choices. To initiate a desired
mode, press the mode button once more, or, after 4 seconds of no button activity, the control
will automatically activate the last mode option displayed.
CHOOSING A HUMIDITY SETTING
Press the up or down arrow key until the present humidity setting
and % symbol are flashing. Use the up/down arrow buttons to adjust
humidity setting in 5% increments. After 4 seconds of no button activity, presently selected
humidity setting will be programmed. The current ambient humidity will then be displayed.
When ambient humidity exceeds the chosen setpoint a water drop icon will appear and the
ventilator will operate in high speed until the humidity level drops below setpoint. Available
humidity setting range: 20-80%.
In cases where humidity control is not desired or practical, use the arrow keys to toggle the
humidity “setpoint” to one click above 80% or one click below 20%. Also use arrow keys to
reactivate humidity control.
NOTE:
Generally, a humidity setting of 40-60% is desired. While your ventilator is not a
dehumidifier, ventilation can have the effect of reducing indoor humidity when exchanging
moisture-laden air from the interior space with less humid, fresh air from outside.
OPERATION MODES
OFF:
Ventilator is off, but the control itself is on and will display ambient
humidity level.
STANDBY:
Ventilator is idle. During this mode, a static pause icon will display.
During standby mode the ventilator will temporarily switch to high speed on
demand from the lumina humidity sensor or a timer.
LOW SPEED:
Ventilator runs in low speed continuously. During this mode, an
animated 3-blade fan will display. During low speed mode the ventilator will
temporarily switch to high speed on demand from the lumina humidity sensor
or a timer.
HIGH SPEED:
Ventilator runs in high speed continuously. During this mode,
an animated 6-blade fan will display. Ventilator will remain in high speed on
demand from the lumina humidity sensor or a timer and continue in high speed
after the humidity/timer demand is met.
20 LO/40 STANDBY:
Ventilator cycles continuously between 20 minutes of low
speed operation and 40 minutes of standby operation. During low speed cycle,
the fan 3-blade fan icon will animate and the pause symbol will flash twice
every 5 seconds. During the standby cycle, the pause icon will be static and
the fan icon will flash twice every 5 seconds. During 20 lo/40 standby mode the ventilator will
temporarily switch to high speed on demand from the lumina humidity sensor or a timer.
RECIRCULATION MODES
RECIRCULATION:
Ventilator continuously recirculates air within the home and
does not bring in air from outside, i.E. Air exchange does not occur. During this
mode an animated cycling arrow will display. During recirculation mode the
ventilator will temporarily switch to high speed on demand from the humidity
sensor or an external timer.
20 LO/40 RECIRCULATION:
Ventilator cycles continuously between 20 minutes
of low speed operation and 40 minutes of recirculation operation. During the low
speed cycle, the fan will animate and the recirculation ring will flash twice every
5 seconds. During the recirculation cycle, the recirculation arrow will animate and
the fan icon will flash twice every 5 seconds. During 20 lo/40 recirculation mode the ventilator
will temporarily switch to high speed on demand from the lumina humidity sensor or a timer.
USING THE HIGH SPEED TIMER
For timed high speed operation, press the hourglass button once for 20
minutes, twice for 40 minutes, or three times for 60 minutes. Hourglass
icons will appear from left to right at the bottom right of the LCD display
and a high speed fan icon will appear on the screen. After 3 seconds of
no button activity the high speed cycle will begin. As each 20 minute cycle
expires, one hourglass icon will disappear from right to left. You can manually turn off the timer
cycle by pressing the hour glass button until all the hourglass icons disappear.
If you would like to view or change modes during a high speed call, simply use the mode and
arrow keys and the chosen mode will resume/commence after the timer cycle has expired.
NOTE:
Additional timers are compatible with your control, however, the control will not indicate
that these external timers are active (i.E. It will continue to display present mode of operation
only). You can change the desired mode of operation during a timer cycle; it will commence after
the timer cycle has expired.
MAINTENANCE INDICATOR/RESETTING MAINTENANCE CLOCK
Your control has a maintenance run clock (it only counts time when the
ventilator is turned on). Factory default for the maintenance clock is 3
months, at which time a wrench icon will appear in the upper right of
the LCD screen and a yellow led will light. This indicates that it is time to
check your ventilator to see if it needs cleaning and to see if your filters
