Bathroom Fan Countdown Timer

The TOPGREENER TGT08-4 replaces a standard wall switch to run lights or ventilation fans for a preset period. Eight buttons offer fixed delays of one, five, ten, thirty, forty-five minutes and one, two, four hours. A blue LED next to each button shows the active setting and can be customised. The unit is rated for 120 VAC, handling incandescent loads up to 1200 W, LED loads up to 600 W and motors up to one-half horsepower.

Neutral Wire Installation Requirement

A neutral conductor must be present in the wall box for the timer to operate. The switch uses screw terminals and fits a single-gang opening, but the decorative wall plate is sold separately. Because the device is single-pole only, it cannot be used in three-way or multi-location circuits. UL listing confirms compliance with applicable safety standards for the stated voltage and load ratings.

Simple Retrofit With One Wiring Constraint

Installation consists of removing the old switch, connecting line, load, neutral and ground to the labelled terminals, and mounting the timer in the existing box. The most common issue is discovering that no neutral wire was pulled to the switch location, which prevents the timer from powering its internal circuitry. The operating temperature range of thirty-two to one hundred four degrees Fahrenheit covers typical indoor environments. No programming or batteries are required.

Questions about this item

Will the blue LED indicators or the internal relay need replacing after extended use?

The blue LED indicators are built into each button and are not user-replaceable; the internal relay is rated for the listed 15 A / 1200 W loads and has no specified replacement interval.

What is the longest single countdown the switch can run before it must be reset?

The maximum selectable delay is 4 hours, after which the load turns off automatically and the timer must be started again for another cycle.

How much heat does the unit produce when a bathroom fan runs continuously for several hours?

Operating temperature range is 32 °F to 104 °F; the switch is designed to dissipate heat within that range during continuous 1/2 HP motor loads.
