Installation Inspection The ECHO units are delivered on a pallet. Handles and necessary components are placed inside the unit. The inspection hatches are opened by the use of a 5/8” (16 mm) cap key, see figure below. To facilitate opening and closing of the inspection hatches, install the 2 handles that are placed inside the unit on delivery. The door handles must be locked before the unit is put into operation to ensure the required level of safety for the unit.

Installation (Cont'd) Port configuration The unit has hinged access doors on the front and removable panels on the back. The front left and right access doors are hinged for easy access to the filters, exchanger and fan motors while the back left and right panels are fastened to the unit. When facing the front access doors the outdoor and exhaust air duct connections are on the left side of the unit and the supply and return air duct connections are on the right side of the unit.
Installation (Cont'd) Installing the BYPASS module (BPM1434 module) accessory The BPM module accessory is an insulated recirculation damper box that is mounted on the side of the unit, over the outdoor air duct connection of the unit. It extends the outdoor air duct connection and has another duct connection for recirculating indoor tempered air. The purpose of the BPM1434 module accessory is to offer an alternative exchanger defrost method.
Installation (Cont'd) Weather hoods, louvers, ducts and dampers (Cont'd) Dampers are strongly recommended on both the supply & exhaust airstreams for proper unit operation and are often required to conform to regional requirements for ventilation systems. Dampers prevent unconditioned air infiltrating the space when the unit is stopped or during the exchanger defrost sequence.
Installation examples (Cont'd) * Drawings are illustrations only and actual port locations and airflow directions may vary, consult unit spec sheets. * The BPM might need to be ducted depending on location of the installation. It is the responsibility of the installer to ensure all ductwork is sized and installed as designed to ensure the system will perform as intended. The amount of air (CFM) that an HRV/ERV will deliver is directly related to the total external static pressure (E.S.P.) of the system.

Unit components and electrical connections Electrical connection box All electrical connections are made in the electrical connection box found on the front of the unit. Remove the access panel by unscrewing the fasteners.
Unit components and electrical connections (Cont'd) Main power & circuit breaker connection The main power connection of this unit must be preceded by an all pole circuit breaker. The connection from this circuit breaker to the unit main power knockout must be run in flexible conduit (field supply & specify) for the reason that the unit electrical connection box is mounted on a hinged access panel used to service the fan motors.
Unit components and electrical connections (Cont'd) Pressure transducer modules As mentioned in the previous section, this unit is equipped with two (2) pressure transducer modules referred to as Pressure transducer exhaust (PTE) and Pressure transducer supply (PTS) (see unit wiring diagram). They are located inside of the unit on the return air side and can be accessed by opening the larger hinged access panel. Each module has two (2) pressure transducer.
Unit components and electrical connections (Cont'd) Installing the supply air temperature sensor A temperature sensor, as seen in the illustration below, is enclosed in the unit packaging on delivery. This temperature sensor is the supply air sensor and it must be mounted in the supply air duct no closer than 10 ft. (3 m) away from the unit. Using a two (2) wire conductor (field supplied and specified), connect the supply air sensor to terminal TB3 30-31 (see unit wiring diagram).
Unit components and electrical connections (Cont'd) Installing the unit external display The unit external display is delivered with a 32 ft. (10 m) cable that is used to connect the display to the Corrigo™ controller in the electrical connection box. See figure below for instruction on wiring the cable to the display. Find an appropriate place to install the display within 32 ft. (10 m) of the unit. Supplied cable comes with a connector to connect the display to the corrigo.
Unit operation System operation modes This unit has the following operation modes: • Starting up: The unit is performing the start sequence • Normal run: Normal speed or reduced speed ventilation active • Stop fan: The unit is performing the stop sequence • Stopped: Ventilation stopped • Recirculation: Exhaust air fan is stopped, Supply air fan is active and BPM module is open, room air is recirculated through the unit (Only available if unit is equipped with BPM module).
Unit operation (Cont'd) Controller display & start screen On startup, the start screen will be visible on the unit controller’s external display. The first line is the unit model name followed by the date and time (24h clock) and the current system operation mode. H2800Xi YYYY-MM-DD HH : MM SYSTEM: STOPPED The unit external display is used to configure & commission the unit. It is also used to troubleshoot and handle alarms generated by the controller.
Unit operation (Cont'd) Airflow control (CAV & airflow set points) By monitoring the pressure drop over the inlet ring of both fans, the unit control can calculate the airflow moved by each fan using a technique based on the Bernoulli and continuity equations. The unit control will modulate the analog output sent to each EC fan motor in order to maintain a given airflow set point. Follow the steps below to enter the airflow set points of the supply and exhaust air fans.
Unit operation (Cont'd) Time settings & schedule The unit controller has a year-based 24h clock function. This means that a weekly schedule with holiday periods for a full year can be set. The clock also has an automatic daylight saving time change-over. To set the date and time follow the steps below. 1 Time settings Temperature Go to Time settings by using the UP/DOWN arrow buttons.
Unit operation (Cont'd) Time settings & schedule (Cont'd) The schedules are set to inactive (00:00 – 00:00 Monday to Sunday & holidays) from the factory. If it is intended to have the unit operated by schedules then they have to be programmed in the field. Once the airflow set points, the time/date and the schedules have been programed, the unit will start up and operate at the given airflow set point when a schedule is active.
