Selecting the Ventilation Rate That is Right for You
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.
I. Continuous Ventilation
This mode of operation provides continuous ventilation within the home. You may, for example, select Continuous Ventilation at low speed for normal operation and increase to high speed during increased activity levels, such as cooking and showering, etc.
II. 20 Minutes On, 40 Minutes Standby
This mode of operation provides 20 minutes of ventilation each hour. You can use this ventilation mode at low speed for low household activity levels or when the home is unoccupied.
III. 20 Minutes On, 40 Minutes Recirculation
Ventilates for 20 minutes and recirculates the household air every 40 minutes each hour. This mode is not applicable if your HRV is connected to a forced air system.
IV. Continuous Recirculation
Continuously recirculate your household air (no ventilation). This mode is not applicable if your HRV is connected to a forced air system.
Recirculation
Recirculates existing household air without introducing fresh air. Recirculation modes (III and IV) are not applicable if your HRV is connected to a forced air system, since your forced air system already circulates the household air. Recirculation modes are unavailable on some models.
Note
Due to ongoing research and product development, specifications, ratings, and dimensions are subject to change
without notice.
Warning
Disconnect the power from the unit before cleaning or servicing.
To prevent electrical shock, it is extremely important to confirm the polarity of the power line that is switched by
the safety (disconnect) switch. The hot line (black) is the proper line for switching. Use either a voltmeter or test lamp to confirm the absence of a voltage between the disconnect switch and ground (on the cabinet) while the door is open. This procedure must be followed, as dwellings are occasionally wired improperly. Always ensure the proper grounding of the unit.

How the Dehumidistat Works
High indoor humidity levels, during the heating season, 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. These conditions usually occur during the heating season when outdoor temperatures are less than 15oC (59oF). During the heating season, the operation of the HRV may reduce indoor humidity levels sufficiently to eliminate the need for further dehumidification. If your home requires further dehumidification, use the dehumidistat feature located on the main control. This feature aggressively addresses high indoor humidity levels by initiating high speed ventilation when the indoor humidity levels rise above the adjustable set point on the control. Refer to the Main Control instructions located in the Installation Guide for instructions on how to set the dehumidistat. The dehumidistat function should be set to off for all seasons except the heating season because a dehumidifying effect occurs only when the outdoor air is dryer than the indoor air. (Refer to the Control Instructions for information on how to set the dehumidistat).
Your Lifestyle RNC Digital Control has an adjustable dehumidistat which can be set to achieve a further dehumidification effect from your HRV. High speed ventilation will be initiated upon exceeding the dehumidistat set point regardless of the mode and speed of operation. Once the humidity in the house is reduced, the HRV will revert back to its previous setting.
We suggest operating the HRV for the first few days without use of the dehumidistat function to observe if a further dehumidification effect will be required. The dehumidistat operates in % of RH (relative humidity) with 80 being high and 20 being low. Set the dehumidistat to 80% to disable. If after a few days, further dehumidification is required (the house is still too humid), set the humidity level to a lower amount.
The average person is comfortable between 30% and 50% RH. The dehumidistat should be set to off for all seasons except the heating season. Off is achieved by setting the dehumidistat to 80.
Dehumidistat Notes
Dehumidistat Disable automatically disables the dehumidistat function on the main control when outdoor
temperatures exceed 15oC (59oF) for a full 24 hour period. All other HRV features and functions operate normally while the dehumidistat function is disabled.
Dehumidistat Re-Enable automatically re-enables the dehumidistat function if either the outdoor temperature
drops below 15oC (59oF) for a full 24 hour period or if the HRV is reset (unplugged for 30 seconds).

99-DX01 Continued
The Lifestyle RNC Digital Control Gives you 4 Mode Selection
The Lifestyle RNC Digital Control has 4 operational modes and 2 speeds on each mode to adjust indoor ventilation levels.
Experiment with the ventilation levels in your home to evaluate the best amount of ventilation to suit your home and preferences.
I. Continuous Ventilation Mode
This is the most popular mode since it provides continuous ventilation within the home. You may, for example, select Continuous Ventilation at high speed for high household activity levels or Continuous Ventilation for lower activity levels.
II. 20 minutes On, 40 minutes OFF Mode
This operational mode will provide 20 minutes of ventilation each hour. You may wish to use this ventilation mode in low speed for low household activity levels or if the home is unoccupied.
III. 20 minutes On, 40 minutes Recirculation Mode
The operational mode provides 20 minutes of ventilation (fresh air) and 40 minutes of recirculate air. Use this mode only if your HRV is not connected to a forced air system (the forced air system has already circulated household air).
IV. Continuous Recirculation Mode
This operational mode recirculates your household air (no ventilation). Use this mode only if your HRV is not connected to a forced air system.
How to Synchronize the Humidity Setting
The Lifestyle RNC Digital wall control has a feature that will allow it to be synchronized with other humidity instruments in your home.
1. Turn off the control with the ON/OFF button.
2. Simultaneously press and release the ON/OFF button and the 20/40/60 minute high speed
override button.
3. Use the Up/Down buttons to adjust the humidity indicator on the display screen to the number
of degrees difference between your humidity measuring device. Minus is indicated by flashing.
4. Press the MODE button.
Attention
Only one main control can be installed on your system. Recirculation is not available on all models. Timers will not function when mode of operation is set to “OFF”, unless specifically installed for that function. (See
