Humidity Control
Designed primarily for use with our low price HRV (Heat
Recovery Ventilator) units, the Humidity Control helps control
indoor maximum humidity level during fall, winter and spring.
This control should not be installed in a house already
equipped with other main controls (except the 3-position
switch). You will find a relative humidity % scale instead of a
temperature scale meant to reduce the window condensation
problems.
3-position switch
Some model may come with a 3-position mounted switch on
the electical box on the exterior lower right front side. It is
basically an airflow control that gives the customer the choice
between the low and high speed or the OFF (REMOTE) posi-
tion. This OFF (REMOTE) position does not deactivate the
optional controls.

CAUTION
All models require a main control.
