OPERATION (CONT'D)

PRACTICAL

TIPS

To avoid window condensation:

•It is not necessary to change the humidity control every day. Monitor the average weekly temperature or experiment with various settings until you find a level that is comfortable for you. Adjust the control when needed.

OPTIONAL REMOTE CONTROLS	gauge wire is recommended.
	* All controls are low voltage. 18 to 24

Dehumidistat - MD-2W- The wall mount dehumidistat monitors the humidity level in the area it is installed. When the humidity level rises above the desired set-point, the HRV will activate to high speed/override mode. Once the humidity level returns to desired condition, the unit will return to the normal mode.

Dehumidistat - MD-4W- The wall mount dehumidistat offers the same features of the dehumidistat I plus additional off/on control for the HRV. Dial illuminates when in override mode.

NOTE:

A dehumidistat is ideal for use in energy efficient houses where indoor humidity (during the heating season) is higher than outdoor levels. High humidity is a major cause of structure damage and IAQ problems such as mold and mildew.

Air Quality Sensor - AQS - The wall mount Air Quality Sensor (AQS) monitors indoor air quality and activates the override mode when carbon monoxide, formaldehyde, benzene, volatile organic compounds and other pollutants are detected. The unit will then return to normal mode once the air pollutants are reduced to a pre-determined lower level.

* This control is not a warning device.

15-min Timer - RT-15M- The 15-minute remote timer is typically installed in areas where contaminated such as moisture and odors, are produced. Simply push the button and the HRV will activate to high speed for 15 minutes. Up to 5 electronic timers can be installed throughout the building at a distance of up to 500 feet (152 meters) from the HRV.

PRACTICAL TIPS

NOTE:

OPTIONAL DIGITAL CONTROL

DIGITAL DISPLAY DEHUMIDISTAT CONTROL DMFC-REC

When an digital control is installed, the rocker switch located on the right hand side of the HRV will be automatically deactivated giving the user complete control from wherever he/she wishes to mount the control pad.

NOTE:

The override speed cannot be set at a fan speed lower or equal to the normal operating fan speed. For example, if the unit is normally operating at a medium fan speed, the override fan speed will be automatically set to high.

NOTE:

DMFC-REC model, changing the override speed will change default override speed for other external controls.

EXAMPLES:

Shows Indoor Humidity Level This control will not read below 29% RH

OVERRIDE TIMER

When pressed, unit will provide high speed ventilation for one 15,

30 or 60 minute period.

MAINTENANCE LIGHT

Light comes on when it’s time to clean unit.
