Press “PUSH” until the desired ventilation operation is selected.
There are three selections: High, Low, Intermittent. The power
indicator light indicates which mode has been selected.
High — This mode is recommended for the removal of excess
pollutants and humidity. The ventilator will operate at its
maximum speed continuously. The power indicator light will be lit
red when this mode is selected.
Low — This mode is recommended for normal daily operation.
The ventilator will operate at its minimum speed continuously. The
power indicator light will be lit yellow when this mode is selected.
Intermittent — This mode is recommended when the inside air is too
dry in the heating season or too humid in the cooling season. The ven-
tilator will operate at its minimum speed for 20 minutes per hour and
be off for 40 minutes per hour. The power indicator light will be lit
green when this mode is selected.
Off — To turn the ventilator off, press “Push” until the power indica-
tor light is turned off.
ERV with Latent Control
A07621
Your ERV is designed to operate as an integral part of your total heat-
ing and cooling system.
Low Exchange Mode—If the relative humidity inside the building
is lower than selected, air exchange would occur with the outside at
high speed. If the relative humidity level inside the building is higher
than selected, air exchange would occur outside at low speed. This en-
sures continuous air exchange for constant air quality.
Intermittent Mode—If the relative humidity inside the building is
higher than selected, no air exchange would occur, and the system
would turn off. If the relative humidity inside the building is lower
than selected, air exchange would occur with outside at high speed.
This mode is ideal for maintaining the proper humidity level when the
continuous mode cannot.
