the set time on the Timer Switch (20 min, 40 min, 60 min).
When a timed cycle is complete the unit returns to normal run mode set on the Wall Control unit. When a Timer Switch is
activated, the other Timer Switch blinks its LED and Wall Mount Unit lights up its REMOTE icon on the LCD screen indicating that
the ERV has been forced into High Speed Mode.
If there are more than one Timer Switches activated, the Timer Switch with the longest time takes control, and only that Timer
Switch can turn o the timer switch operation. All 3 LEDs will blink to indicate error if the Control Board reports error or the Timer
Switch loses communication with the Control Board.
