SAFETY CONSIDERATIONS

Recognize safety information. This is the safety-alert symbol ! When you see this symbol on the unit and in instructions or manuals, be alert to the potential for personal injury.

Understand these signal words; DANGER, WARNING, and CAUTION. These words are used with the safety-alert symbol. DANGER identifies the most serious hazards which will result in severe personal injury or death. WARNING signifies hazards which could result in personal injury or death. CAUTION is used to identify unsafe practices which may result in minor personal injury or product and property damage. NOTE is used to highlight suggestions which will result in enhanced installation, reliability, or operation.

OPERATING YOUR HEAT RECOVERY

VENTILATOR (HRV) WITH ONETOUCHt CONTROL:

Press “PUSH” until the desired ventilation operation is selected. There are three selections: High, Low, Intermittent. The power indi- cator light indicates which mode has been selected.

High: This mode is recommended for the removal of excess pollu- tants and humidity. The ventilator will operate at its maximum speed continuously. The power indicator light will be lit red when this mode is selected.

Low: This mode is recommended for normal daily operation. The ventilator will operate at its minimum speed continuously. The power indicator light will be lit yellow when this mode is selected.

Intermittent: This mode is recommended when the inside air is too dry in the heating season or too humid in the cooling season. The ventilator will operate at its minimum speed for 20 minutes per hour and be off for 40 minutes per hour. The power indicator light will be lit green when this mode is selected.

Off: To turn the ventilator off, press “Push” until the power indicator light is turned off.

OPERATING YOUR HEAT RECOVERY VENTILATOR (HRV) WITH BASIC, STANDARD AND AUTOMATIC CONTROL

Your HRV is designed to operate as an integral part of your total heating and cooling system. With the exception of high capacity models, which are available with standard controls only, all HRVs offer 4 control options (See Fig. 2).

SBasic Controls: Allow the user to manually set the unit to low- or high-fan speed as required to maximize comfort. Controls may be unit mounted.

SStandard Controls: Offer automatic dehumidistat control and the option to select low speed or intermittent fan during heating season.

SAutomatic Controls: In addition to the operational features found with standard controls, automatic controls feature a recirculation mode. Not for use with forced-air HVAC systems.

Fan Speed Control—Enables user to modulate fan speed from low to high.

Dehumidistat Control—Allows the user to select the relative hu- midity level at which the unit would change fan speed to avoid con- densation problems while heating during the winter months. (See Table 1).

Continuous Mode—If the relative humidity inside the building is lower than selected, air exchange would occur with the outside at low speed. If the relative humidity level inside the building is higher than selected, air exchange would occur outside at high speed. This ensures continuous air exchange for constant air quality.

Intermittent Mode—If the relative humidity inside the building is lower than selected, no air exchange would occur, and the system would turn off. If the relative humidity inside the building is higher than selected, air exchange would occur with outside at high speed. This ensures minimum air exchange level when the building is un- occupied to minimize operating cost.

Recirculation Mode—If the relative humidity inside the building is lower than selected, indoor air would be circulated and filtered at high speed. If the relative humidity inside the house is higher an se- lected, air exchange would occur with outside at high speed. This ensures continuous movement and filtration of air for maximum comfort.

!WARNING

ELECTRICAL SHOCK HAZARD

Failure to follow this warning could result in personal injury or death.

Before servicing system, always turn off main power to system. Turn off accessory heater power if applicable. There may be more than 1 disconnect switch.
