Optional Main Controls
The amount of ventilation required in your home will fluctuate
according to the activity level in the house. Higher activity levels
require more ventilation.
Main controls can be mounted in a central location of the home
(i.e. beside the furnace thermostat) which will provide the user
with complete control over their ventilation system from a conve-
nient location.
The ON/OFF Switch
The ON/OFF Switch will turn the HRV ON or OFF. Controls with
an ON/OFF switch can be modified to ON/Standby by adjusting
the circuit board DIP Switches (Refer to "Mode DIP Switch
Settings").
The Dehumidstat Dial
Main controls feature a dehumidistat dial. The dehumidistat is
used to reduce high winter humidity levels. The dehumidistat
activates high speed ventilation when the indoor humidity level
exceeds selected setting.
Optional Timers
Timers should be present when the HRV is exhausting from
specific locations i.e bathrooms, laundry rooms. The 20 Minute
Timer is the best selection, however, the crank timer will be nec-
essary if only 2 lead low voltage wires are present.
Only one main control can be installed on your
system.
