Optional Connections:
The unit has an optional terminal block for 24V AC HVAC/AHU blower integration.
The user can connect the HVAC/AHU 24V AC dry contact relay to the terminal block so that when the ERV is operating, the HVAC/AHU blower
operates to help distribute the fresh air through the existing ductwork if needed.
The unit has an optional terminal block for a MANUAL OVERRIDE SWITCH (MOS) connection.
Connect an ON/OFF switch to the terminal block to
manually switch the unit to high speed. When the switch is off, the unit returns to the low speed operation per the OA, RA, and T knobs.
The optional terminal block is not required for the unit.
