DEHUMIDISTAT
Optional Main Control Features
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 convenient
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
Main controls feature a dehumidistat which is used to reduce high
indoor humidity levels during the heating season. The control has a
selector knob with setpoints ranging from 20% to 80% relative
humidity (RH). Most people are comfortable when indoor relative
humidity levels are in a range from 30% to 45%.
The dehumidistat switches the HRV to high speed ventilation when the
moisture level in the home exceeds the desired setpoint. The
dehumidistat should only be used during the heating season. It must be
set to the OFF position throughout the rest of the year.
