Wiring Diagram (cont’d) 3 Furnace / Fan-Coil / Heat Pump Interlock: ! WARNING ! Never connect a 120 volt AC circuit to the terminals of the furnace/fan-coil/heat pump interlock (Standard Wiring). Only use the low voltage class 2 circuit.
HRV/ERV Operational Modes Functionality 4 Off Mode: HRV/ERV fans are off. Defrost damper is closed to prevent cold air from entering the unit. Normal Mode: In Normal mode HRV/ERV fans run and the unit exchanges indoor air with outdoor air. The airflow exchange can be adjusted in four preset airflow values. Normal Mode is intended to be requested by the user for long time HRV/ERV operation.
Programming Instructions for Wall Control Unit (WC100) MODE + _ 5 Normally there will be only one Wall Control Unit connected to Control Board. Multi Wall Control Unit (up to three) is also supported (see page 2). All Wall Control Units will have the same priorities over each other. It means that if multiple Wall Control Units command Control Board differently, the latest command will be executed by the Control Board. Each Wall Control Unit has different address for communication purpose.
Programming Instructions for Wall Control Unit (cont’d) NOTE: There are totally 9 Defrost Maps. Map1-3 are for Aluminum Core (RHRV-D100A). Map 4-6 are for Polypropylene Core (RHRV-D100P). Map 7-9 are for ERV Core (RERV-D100). Factory programmed default DEFR values are Map-1 for RHRV-D100A, Map-4 for RHRV-D100P & Map-7 for RERV- D100. Setting Internal Programming Parameters Mode OFF.
Programming Instructions for Wall Control Unit (cont’d) PROGRAM NO BAL Press + button. The value is changed to disabled. (Manual Balancing mode - for units without built in automatic Electronic Air Balancing) Press + button again. The value is changed to enabled. When you select the desired setting, press MODE button. The setting is reprogrammed with the new value. If Airflow Balancing is enabled, after pressing the MODE button, the unit jumps to Wall Mount address setting.
HRV and ERV Typical Installations (Deluxe Series) 8 Typical Installations for House Fully Ducted System This is a stand alone HRV/ERV system which is not connected to a force air system. Stale air is drawn from key areas of the home (bathroom, kitchen) while fresh air is supplied to main living areas. 2 Single Vents SVE-50 and SVI-50 Shown. “Fresh Air/ Exhaust Air Vents Installation” Wall Cap Exhaust/Intake WCE-5, WCI-5 shown *Re - Circulation Efficiency If distance “X” is 5ft - 99.7% “X” is 3ft - 96.
HRV and ERV Typical Installations (cont’d) 9 HORIZONTAL • 32” clearance is recommended for cleaning of the core/servicing the unit. (use appropriate access door size) • Dampers are installed for horizontal installation. For vertical installation both dampers have to be turned so they can open properly and close when there is any backdraft. • Make sure no screw will interfere the function of the backdraft damper flaps while installing the duct work to the HRV/ERV.

Air Flow Balancing 11 For units without built-in true Automatic Electronic Air-balancing and for cross verification only Balancing Procedure It is required to have balanced air flows in an HRV/ERV. The volume of air brought in from the outside must equal the volume of air exhausted by the unit while running at normal speed.
Air Flow Balancing (cont’d) 12 DUCT DIAM. CROSS SECTION AREA *For balancing, extension box cover plate is 5" 0.136 sq. ft. provided with 3 holes on supply side and 3 6" 0.196 sq. ft. holes on exhaust side. *Do not use pitot tube to open holes in the insulation as it may block/damage the pitot tube. *Take 3 readings on each hole and average all 9 readings for supply and same for exhaust. *After finish balancing, plug all six holes with plastic plugs provided with the unit. Opening area: 0.136 sq.ft.
Maintenance (cont’d) 13 Annual Maintenance Repeat steps 1 to 5 from the previous section and continue with the following steps: 1.
Troubleshooting (cont’d) PROBLEMS 14 POSSIBLE CAUSES SOLUTION - loss of communication with the Control - check wall control connections - Error Code “E1" 4. “Wall Mount Board. HRV/ERV switched to OFF mode Unit” showing automatically. error Codes: - clean temperature sensor, if it still - defrosting Temperature Sensor Failure. - Error Code “E2" Blinks with the current operational display. shows “E2" error replace temperature HRV/ERV does not perform defrost cycles.
