Modes of operation

1. Continuous / Ventilation Mode
In this mode of operation, both fans are operating and exchanging air with the outside. The heat recovery ventilator (HRV) constantly exchanges the air at
the rate you select, either at low or medium speed, and switches to high speed when activated by an optional remote control. The "Low" and "Med" fan
speed selection will cause the unit to operate in continuous exchange mode at a reduce exchange rate. Continuous mode is recommended, since pollutants
are slowly but constantly being generated in a building.
2. Recirculation Mode
In recirculation mode, the supply motor continues to run and a damper moves to block off air entering from outside, drawing air instead from the conditioned
space. The exhaust to outside motor is OFF when in recirculation mode.
3. Intermittent / Standby Mode
The system is always on standby and operates at high speed when activated by an optional remote control (required): "Standby" should be selected if
the user wishes to stop the unit from continuous exchange.
4. Defrost by Recirculation
A preset defrost sequence is activated at an outdoor air temperature of -5ºC (23ºF) and lower.
During the defrost sequence, the motorized damper in the bypass module (BPM) temporarily blocks the incoming fresh air stream so that the warm air
from the room can circulate through the HRV. The exhaust blower shuts down and the supply blower switches into high speed to maximize the effectiveness
of the defrost strategy. During this cycle, the unit will not create a negative pressure. Please note that these systems are configured to defrost with the
BPM devices installed on the fresh air from outside port. Alternate configuration are available by contacting our technical support department.

Setting speed

The ERV is shipped from the factory on low speed, intermittent operation can be obtained by toggling switch located on outside of cabinet. External
low voltage contacts allow for high speed operation when optional remote control is used.
