Timers are available as wired or wireless. The timer will override the operational mode of the
control (regardless of the setting) and initiate HIGH fan speed Ventilation for 20, 40 or 60
minutes. The ERV will return to the selected operational mode and fan speed setting upon
completion of the timer cycle.
Using Timers
Press the button to initiate high speed ventilation for 20, 40 or 60 minutes. The corresponding
status light will illuminate to indicate either 20, 40 or 60 minutes of high speed fan operation.
Press the button until the status lights are no longer illuminated to cancel high speed timer
operation.
Optional Lockout Mode
The Wired Timer has a lockout mode feature that can be set to disable the timer. Set the
lockout mode by holding the button for five seconds. Disable lock-out mode by holding the
button for 5 seconds. Connect to 3-wire, 20-gauge (min.) low-voltage wire and install in a
standard 2 x 4” (51 x 102 mm) electrical box.
The Wireless Timer pairs wirelessly to the control. Wireless Timers have an estimated range of 40 feet (12 meters) with no
obstructions. To increase the range of the timer, a Wireless Repeater may be used. Multiple timers can be paired to a single control.
They are designed to be mounted in a standard 2 x 4” (51 x 102 mm) electrical box or surface mounted to a wall.
This device is used to extend the range of the Wireless Timer. The Wireless Repeater plugs directly
into a 120 V power outlet.
The Wireless Repeater should be installed at the halfway point between the 20/40/60 Minute Wireless
Timer and the control if the timer is out of range.
When the Wireless Repeater is positioned correctly, a solid green LED will illuminate indicating the
Wireless Repeater has a strong connection to the main wall control and may be moved farther away if
necessary.
* Refer to “Installation and Operation of Wireless Repeater (435249)” on page 23.
Replacing The Battery
The red LED battery indicator will illuminate when the battery on the
timer needs to be replaced. Replace the battery by:
• Pulling the face plate off the wall.
• Replacing the battery located on the back of the Timer Face Plate.
• Re-attaching the face plate to the back plate. Be careful not to
