General Information Heat Recovery Ventilators (HRV) are designed to supply fresh air to a building while exhausting an equal amount of stale air from the building. An energy savings is experienced during the process by reducing the heating (or cooling) requirements.

1 CONTROLLING YOUR HRV Today’s modern, tight buildings require fresh outdoor air to maintain a healthy indoor air environment. The amount of ventilation you require in the building will depend upon: • The number of occupants and their activity levels • The way the building was built • Your personal preferences for fresh air A Heat Recovery Ventilator (HRV) is an air to air energy exchanger found in modern, energy efficient homes.
2 SELECTING THE VENTILATION THAT IS RIGHT FOR YOU Operating Modes The modes of operation and speeds are used to adjust your indoor ventilation rate. Experiment with the ventilation levels in your home to evaluate the ideal amount of ventilation to suit your home and personal preferences. Operational modes available to you will depend on the main control that is installed. Some features and modes may be unavailable to you.
3 HOW THE DEHUMIDISTAT WORKS During the heating season (winter), high indoor humidity levels have become a problem in many well insulated, tight homes. Excessive condensation on the window is a visual sign of high indoor humidity levels. High indoor humidity levels can result in mold and mildew and the eventual degradation of the building structure itself. Your HRV reduces indoor humidity levels when the outdoor air is drier than the indoor air.

4 MAIN WALL CONTROLS Digital Wall Control (99-DXPL02) Operating Instructions (cont.): Setting the Mode of Operation: There are 5 modes of operation available with this control. Press the Mode Button different modes of operation: • Continuous Ventilation • 20 min. Ventilation / 40 min. Recirculation • 20 min. Ventilation / 40 min. OFF • 10 min. Ventilation / 50 min.
5 TIMERS AND REPEATERS Depending on the type of HRV installation, you may have timers in areas such as restrooms. The timer will override the operational mode (regardless of the setting) and initiate HIGH fan speed Ventilation. Upon completion of the timer cycle, the HRV will return to your selected operational mode and fan speed setting.
5 TIMERS AND REPEATERS 20/40/60 Minute Timer (99-DET01): (1) Select Button (2) 20/40/60 minute status lights Press the Select Button on the timer to initiate high speed ventilation for 20, 40, or 60 minutes. The 20/40/60 minute status lights indicate high speed operation. Lockout mode is useful if you wish to disable the timer: • Enable Lockout Mode by holding the Select Button for 5 seconds. • Disable Lockout Mode by holding the Select Button for 5 seconds.
6 MAINTENANCE INSTRUCTIONS Several maintenance procedures are required to keep your HRV in good working order. The table below provides the required maintenance, service interval, and procedural steps. Table 4.1 - Maintenance Procedures Type Inspect Exterior Hoods Interval Monthly Clean Air Filters Quarterly Procedure Make sure the exhaust and fresh air supply hoods are not blocked or restricted by leaves, grass, or snow.
