Enerlites Air Circulators are designed to automate a ventilation fan hourly to cycle out stale air and maintain fresh air indoors. There are two models available – DWTS, a single load fan-only control, and DWTOS, a dual load wall switch that controls both a light and a fan. The dual load switch includes a PIR motion sensor for lighting control, which can detect motion in an area up to 600 square feet to activate a light. Both Air Circulators include easily adjustable timer settings and a manual ON/OFF switch to override automation. Running a fan periodically increases the airway to ensure that the indoor air is always fresh, clean, and comfortable. Complies with ASHRAE 62.2.

Hourly Automation with Countdown Timer

his switch timer features a manual ON/OFF button so that you can control the air circulator as you please. After the fan has been turned ON manually, it will shut OFF after a pre-selected amount of time to conserve energy and ensure that the fan is never left on by mistake. This timer setting is adjustable.

PIR Motion Detection

This in-wall fan timer also includes a built-in motion sensor light switch. The PIR motion sensor detects movement in a space up to 600 square feet to activate the lights accordingly. This device includes both occupancy and vacancy modes, as well as a manual ON/OFF switch and adjustable time delay.

Fresh & Clean Indoor Air Quality

Ideal for keeping indoor air fresh in both high humidity regions and colder regions where doors and windows may be closed for nearly 24 hours each day.
