Remote Control Devices

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.
