How To Choose A Fan Control

Fan controls benefits vary by type, but all have one thing in common: they help the homeowner or business owner save energy, which helps save money.

To choose a fan control, you must first decide which features are important to you, such as programmable, clock display, variable speeds, continuous speeds, and ability to control functions (i.e. light and fan) independently.

Some fan controls, such as a programmable bath control fan can replace a traditional wall switch for both the bathroom light and bath fan. The control enables you to operate the fan either continuously at variable speeds or intermittently, while also allowing independent light and fan control. Typical features include 24 hour programming, coupled with a LED clock display.

A fan speed control enables the user to designate a desired speed or air on a ventilation device. Variable speed controls can be controlled in increments (2 speed or 4 speed, for instance) or continuously. The multiple fan speed control is a highly desired fan control feature.

Dehumidistat and humidistat controls are helpful in turning off a ventilation system once the relative humidity reaches a predetermined level. With preset time controls, the fan is prevented from manually being shut off; an important consideration in preventing bacteria and mold growth in a bathroom, both in a residential and retail setting. While these types of controls are likely used in residential bathrooms to control excessive moisture, they are helpful in damp basements, restrooms, warehouses, and air conditioned rooms in industrial and commercial establishments alike.

Most modern fan controls are Energy Star efficient and remain programmed even in the event of a power outage.
