On/Off Switch
Choose this option for simple, straightforward operation of a single-element Infratech heater. The heater operates at full power when switched on and turns completely off when not needed. This control is only available for single-element heaters and is a good choice when adjustable heat levels are not required.

Duplex/Stack Switch
Designed for dual-element Infratech heaters, this control allows each heating element to be operated independently. Turn on one element for approximately half heat output or both elements for full heat output. This provides simple two-stage heat adjustment without the added cost of a fully variable control system, and is the most popular option used for dual element heaters.

INF Input Regulator
The INF regulator provides adjustable heat output for compatible single-element heaters, allowing you to increase or decrease the heat based on comfort and weather conditions. Rather than functioning like a traditional dimmer, it cycles power to the heater to maintain the selected heat level. Choose this option when you want more flexibility than a basic on/off switch without upgrading to an advanced control system.

Control Configuration and Mounting Options
All three control types are available in single-control or double-control configurations. Mounting options include in-wall controls for indoor or protected outdoor areas, in-wall controls for exposed outdoor areas, and surface-mounted controls for exposed outdoor areas. Select the enclosure and mounting style that matches the control location and its level of exposure to weather.
Flush-Mount Kit
The flush-mount kit recesses the heater into the ceiling for a clean, built-in appearance. This option is only compatible with the W-Series and WD-Series heaters. Special installation considerations and requirements apply for flush-mount applications. Refer to the installation manual for complete steps, specifications, and requirements before installation.

Drop-Pole Mount
The drop-pole mount suspends the heater below a high, vaulted, or uneven ceiling, helping position it closer to the recommended heating height. The adjustable pole extends from approximately 29 to 72 inches and conceals the electrical conduit within the pole for a finished appearance. Standard options are commonly offered in white, black, and bronze, with additional finishes potentially available by special order.

Freestanding Pole Mount
The freestanding pole mount provides a permanent installation when wall or overhead mounting is not available. It supports compatible heaters using a dedicated pole, crossbar, and bracket configuration selected for the heater model and length. Proper structural support and placement are required; refer to the installation manual for mounting requirements, clearances, and installation details.

Important Mounting Considerations...
Mounting accessories are model-specific and may not be interchangeable between heater series or configurations. Verify compatibility, clearances, mounting requirements, and electrical needs before ordering. All installations must follow Infratech guidelines, local codes, and be completed by a qualified licensed electrician. For assistance selecting the right mounting solution, contact one of our professionals.
