FUNCTION & CONTROL Model 500 Only

Operating the ControlAir 15

Self Test

Plugging in the HRV/ERV energizes the unit. A self test function will be performed every time the HRV/ERV is energized (refer to “Self Test” for more details). After the self test has completed successfully the HRV/ERV will default to Speed 1. This is the factory default setting. Follow the instructions found on the HRV/ERV door to select desired mode and speed, or refer to the instructions found on the following page.

Each time the HRV/ERV is powered/energized the self test function will automatically initiate. During the self test the HRV/ERV will cycle through all the speeds available (1-5), test the damper motor operation and will default back to the previous mode/speed selection, (factory default is Speed 1). Total self test duration is approximately 1 min. 30 sec.

Automatic Defrost Operation

(Not on all models)

The advanced technology of the digital microprocessor automatically activates the defrost system only as it is needed. To be an efficient heat recovery device, the HRV/ERV must effectively provide for core defrost as well as providing efficient heat exchange. As outdoor conditions cool, the temperature sensor (thermistor) tracks the supply air temperature. The thermistor then sends its signal to the microprocessor (circuit board) which initiates only the defrost cycle time required to clear the core. On recirculating defrost models, the core is defrosted when the supply air port is automatically blocked off and exhaust air is redirected back through the HRV/ERV. On damper defrost models, the core is defrosted when the supply air port is automatically blocked off and the warm air surrounding the HRV/ERV is drawn in through the defrost port. The mode indicator will flash RED during the defrost cycle. This dramatic advance makes more energy available for recovery as the unit spends less time in defrost mode. By optimizing the defrost cycle, the HRV/ERV combines money saving performance with a well designed and reliable control system.

Removing and relocating the Control Pad

The Control Pad can be removed and installed in a remote location (100’ wire length max). The Control Pad can be installed in a 2x4 box with a “Decora” type cover plate or can be installed in the optional “Ventilation Dehumidistat” or “Air Sentry”. When the Control Pad is installed in a remote location, all optional controls will still be wired to the Control Module on the HRV/ERV. When remotely mounted on its own, the Control Pad is wired to the Control Module by 3 wire (min. 20 gauge). Connect the colour coded terminals to the corresponding terminals on the Control Module. When the Control Pad is remotely mounted in the Ventilation Dehumidistat or Air Sentry, refer to optional controls page for wiring requirements.

Glossary

DEFROST MODE - to ensure reliable operation during cold weather, the HRV/ERV will automatically cycle through its defrost mode as needed. (not on all models)

DEHUMIDISTAT - a control device that senses the amount of moisture in the air and will activate high speed fan operation when the air moisture level exceeds the control setting. The optimum air moisture level (or relative humidity [Rh]) in the typical home is in the range of 30 to 40% Rh.

RESET - whenever resetting of the HRV/ERV is required, simply disconnect power for 30 seconds.

STANDBY MODE - the HRV/ERV is energized and waiting for fan operation to be initiated by a remote device or manual override.

THERMISTOR - the HRV/ERV's temperature sensor which measures electrical resistance in a known manner, as outdoor temperatures fluctuate.
