Operation
Self Test
The ventilator will automatically initiate a self test
sequence when power is applied. Fan motor is cycled and
then damper motor is cycled. Duration: Approximately 1.5
mins.
How much ventilation do I need?
During seasons when your windows and doors are closed
(winter and summer if air conditioned) the HRV should
operate continuously when the dwelling is occupied, and
either continuously or intermittently when not occupied.
For most installations the HRV will normally be set to oper-
ate continuously on low speed. To suit various lifestyles,
the HRV offers a selection of operating modes.
Method of Operation
Good - intermittent operation at all times
Better- continuous operation during day or occupied
conditions, intermittent at night or unoccupied
Best - recommended continuous operation of both
HRV and furnace/air handler blower
Figure1-Factory DIP Switch Settings
The factory setting of the DIP switches (located on the cir-
cuit board) provides continuous low speed ventilation.
Optional Remote Controls will initiate high speed ventila-
tion.
Remote controls with an ON/OFF switch (refer to "Remote
Control Devices" in this manual) will shut the entire sys-
tem down when the remote control is in the OFF position.
Changing the remote control from OFF to STANDBY can
be achieved by Setting the DIP Switch as per Figure 2.
Figure 2-DIP Switch Settings for Standby (When
using a Remote Control Device that has an
ON/OFF Switch)
This DIP Switch Setting can be adjusted when using a
system control that has an ON/OFF switch (refer to
"Remote Control Devices" in this manual). "STANDBY" is
achieved when the Remote Control Switch is in the "OFF"
position. The Dehumidistat and Timers will initiate high
speed ventilation regardless of the "ON/OFF" switch posi-
tion when this DIP switch configuration is used.

ON
The ventilator automatically operates on its lowest speed
when plugged in or switched on. This setting is factory
supplied from an autotransformer with two selectable low
speeds. To switch to a continuous medium low speed, an
installing contractor must interchange the red and blue
wires from the autotransformer inside the electrical box.
Whether or not this change is made, the HRV will only be
able to access a single selected low speed.
High speed is available with the use of optional remote
controls connected to the appropriate terminals inside the
electrical box.
