Relative humidity sensor dial
OFF / 60% / COMFORT ZONE / 30%
Overrides the ventilation system to high speed once the level of humidity is above the set point.
If the wall control is in CONT or INTERM mode the ventilation system will automatically return to its original mode once the level of humidity is below the set point.
OFF – Sends command to shut down ventilation system.
NORMAL – The ventilation system operates on installers set speeds (CONT and OVERRIDE).
REDUCE – The ventilation system operates at 30% reduction in CONT and OVERRIDE speed.
Note: REDUCE mode will not decrease below the maximum low speed of the ventilation system.
INTERM – Ventilation is halted meaning,automatically stopping and starting at intervals the ventilation system from a command from a remote wall controls.
RECIRC – The recirculation mode recycles already-heated ambient air from a selected area and distributes throughout your home. This enables the ventilation system to have an auxiliary air supply automatically during defrost sequence or when RECIRC mode is selected.
CONT – Provides a continuous ventilation rate. The ventilation system will increase to high from command of remote wall controls.(Recommended for maximum indoor air quality.)
0 – The ventilation system operates at the settings of your RD Series wall control.
20/40 – The ventilation system cycles automatically for 20 minutes at high speed and returns to previous settings (CONT, INTERM or RECIRC, pending settings on the mode selector switch or your RD series wall control.)
30/30 – The ventilation system cycles automatically for 30 minutes at high speed and returns to previous settings (CONT, INTERM or RECIRC, pending settings on the mode selector switch or your RD series wall control.)
Note: The ventilation system will go to high speed if a demand from any remote wall control is activated when in the 2nd stage of cycle. Ex: 40 or 30 minutes.
Orange light = ON (CONT / INTERM)
Green LED light = OVERRIDE (MAXIMUM SPEED)
Light is on when HRV ERV needs to be maintained.
Light is on after 90 days consecutive power to the ventilation system.
To reset the maintenance LED reminder, put the range selector switch to the OFF position.
TIPS: You can also opt to put your ventilation system on INTERM or OFF mode during the warmer months and run it only at night time once the temperature cools down.
