ERV / HRV

DEHUM - will only turn on if humidity is 3% over setpoint. The speed is determined by indoor humidity and outdoor temperature.

Cooling:

AUTO - the ventilator selects the speed based on indoor humidity and outdoor temperature. It may cycle on/off every 30 minutes depending on humidity and outside temperature.

LOW - low speed all of the time. HIGH - high speed all of the time.

If the fan speed is set to Auto and the ventilator wants to run, the fan speed will run at High continuous speed. Otherwise, the fan will stay at the chosen continuous fan speed.

BOOT SEQUENCE

The unit boot sequence is similar to a personal computer boot sequence. Each time the unit is plugged after being unplugged, or after a power failure, the unit will perform a 30-second booting sequence before starting to operate. During the booting sequence, the integrated control LED will light GREEN or AMBER for 5 seconds, and then will shut off for 2 seconds. After that, the LED will light RED for the rest of the booting sequence. During this RED light phase, the unit is checking and resetting the motorized damper position.

Once the motorized damper position completely set, the RED light turns off and the booting sequence is done.

NOTE: No command will be taken until the unit is fully booted.

ELECTRICAL CONNECTIONS

115-VAC Wiring

The ERV/HRV operates on 115VAC. It comes with a power cord attached to unit and ready to plug into a fused outlet. Unit must be grounded for proper operation.

All electrical connections must comply with National and Local Electrical Codes, or other ordinances that might apply.

!WARNING

ELECTRICAL SHOCK / FIRE HAZARD

Failure to follow this warning could result in personal injury, death and/or property damage.

Do not use an extension cord as a power source for operating the ERV/HRV.

12VDC Wiring

The ERV/HRV circuit board, wall control, and accessories operate on 12VDC. See Wall Control section, item Wiring and Fig. 5 and 10 for more information.

ACCESSORIES

20 Minute Timer

A push button timer can be used to override the wall control and put the ERV/HRV into high speed for 20 minutes. Connect switches in parallel and connect leads to ERV/HRV terminals I, OC, and OL (See Fig. 12). Push button locations are ideal in special activity areas, such as, bathroom, or kitchen, where high-speed exhaust operation is needed for a short period of time.

NOTE: The 20 minute timer will not function properly unless ERV/HRV wall control is applied and working correctly. Timing function is internal to electronic circuit board, it is activated by a momentary contact between OC and OL. The I connection is to illuminate the push button. The maximum number of push button timers that can be applied is 5.

60 Minute Adjustable Timer

A 60 minute adjustable timer can also be used to override wall control and put HRV into high-speed operation for a select amount of time. Connect timer in parallel with push button timers, or to ERV/HRV terminals OC and OL. (See Fig. 12.)

The 60 minute timer will provide a minimum of 10 minutes, and a maximum of 60 minutes of ventilation at high speed.
