SEQUENCE OF OPERATION (ERU-1 ONLY)

The sequence of operation displayed below is Innovent's interpretation of what is required for this project. This is subject to review by controls contractor. Innovent will not be responsible for any costs associated with modification of this sequence after the equipment has shipped.

Energy recovery unit DDC specs

STAND ALONE DDC CONTROLLER.

• Provided with required sensors and programming.

• Factory programmed, mounted, and tested.

• User terminal with LCD readout for changing set points and monitoring unit operation.

• User terminal can be unit mounted or remote mounted and is connected by straight through six wire flat cable

SEQUENCE OF OPERATION. The Stand-alone DDC controller shall perform the following control sequence.

UNIT START COMMAND

• Actuators for the outside air heat exchanger face damper and outside air heat exchanger bypass damper are powered.

• DDC controller checks damper actuator end switch status.

• Exhaust fan starts after dampers are open (minimum of 120sec delay, adjustable).

• Supply fan starts 5sec (adjustable) after the exhaust fan.

• Face & bypass operation per below.

UNIT STOP COMMAND (OR DE-ENERGIZED)

• Fans are de-energized

• All damper actuators are de-energized and spring return to their fail position after a 120sec on delay.

DEFROST

• The outside air heat exchanger face & bypass dampers modulate (bypassing outside air around the heat exchanger) to maintain the exhaust air temperature above the defrost set point (set point=34°F).

SUPPLY TEMPERATURE SET POINT

• The unit shall not control to a supply temperature. Any time the existing air handler in the building is in operation, ERU-1 shall operate as a pre-cool/pre-heat for the existing air handler in the building

REMOTE ON/OFF. Unit DDC shall have an input allowing the unit to be started/stopped by others.

ALARM INDICATION. DDC shall have one digital output for remote indication of an alarm condition. (i.e. Blower current/differential pressure switch, damper end switches, freeze stat, fire stat, smoke, dirty filters…).

SEQUENCE OF OPERATION (EVAP-1, 2 ONLY)

The sequence of operation displayed below is Innovent's interpretation of what is required for this project. This is subject to review by controls contractor. Innovent will not be responsible for any costs associated with modification of this sequence after the equipment has shipped.

AHU unit DDC specs

STAND ALONE DDC CONTROLLER.

• Provided with required sensors and programming.

• Factory programmed, mounted, and tested.

• User terminal with LCD readout for changing set points and monitoring unit operation.

• User terminal can be unit mounted or remote mounted and is connected by straight through six wire flat cable

SEQUENCE OF OPERATION. The Stand-alone DDC controller shall perform the following control sequence.

UNIT START COMMAND

• Actuator for the outside air damper is powered.

• DDC controller checks damper actuator end switch status.

• Supply fan starts after damper is open (minimum of 120sec delay, adjustable).

• Cooling operation per below.

UNIT STOP COMMAND (OR DE-ENERGIZED)

• Fans are de-energized

• All damper actuators are de-energized and spring return to their fail position after a 120sec on delay.

COOLING

• Cooling lockout: The cooling will be locked out when the outside air is < 55°F - 2°F hysteresis, adjustable.

SUPPLY TEMPERATURE SET POINT

• The DDC controller will reset the supply temperature set point up & down between the values listed below, in order to maintain the room temperature set point (set point=72°F, adjustable).

• Supply discharge minimum set point: 64 °F, adjustable.

• Supply discharge maximum set point: 80 °F, adjustable.

EVAPORATIVE COOLING SUMP CONTROL.

• Sump drain-out set point: 40°F

• Drain-down: When the outside air temperature falls below the sump drain-out set point, the automatic drain-down system will be energized to drain all water from the evaporative cooling system.

• Sump fill: The sump will fill when the outside air temperature rises above the sump drain-out set point.

• A bleed off valve, positioned between the sump and spray distribution system, is provided to aid in scale build up control

OCCUPIED/UNOCCUPIED MODES.

• Occupied/Unoccupied mode shall be based on an internal 7-day time clock. The schedule shall be set by the end user.

• Occupied mode:

• Supply fan ON.

• Outside air damper open

• Cooling per above.

• Unoccupied mode:

• Supply fan OFF.

• Outside air damper closed.

• When the room thermostat falls out of its set point, a signal shall be sent to energize the unit. Unit shall then operate in occupied mode until signaled to return to unoccupied mode.

REMOTE ON/OFF. Unit DDC shall have an input allowing the unit to be started/stopped by others.

SUPPLY DISCHARGE LOW LIMIT. If the supply discharge temperature drops below 40°F (adjustable), the DDC shall de-energize the unit after a preset time delay.

ALARM INDICATION. DDC shall have one digital output for remote indication of an alarm condition. (i.e. Blower current/differential pressure switch, damper end switches, supply discharge low limit/freeze stat, fire stat, smoke, dirty filters…).

EVENT SHALL SELLER BE LIABLE TO BUYER FOR ANY INCIDENTAL,
