Analog Heater Controller · 2 Zone · Digital Timer · Infratech 30-4046

What this product is for

This two-zone analog controller is used to manage heat output for compatible Infratech radiant heating systems. It provides separate control of two heating zones and adds timed shutoff for applications where users want straightforward manual adjustment with scheduled run time.

Use for

Use for patios, covered outdoor living areas, hospitality spaces, restaurants, and other residential or commercial radiant heating layouts where two separate target areas need independent heat intensity control. It is designed for use with a compatible Infratech solid state relay panel and low-voltage control wiring.

Avoid for

Avoid using this controller as a standalone heater control without the required compatible relay panel. Avoid direct weather exposure where the installation is not protected, and avoid applications that require fully digital programming, smart controls, or more than two independently controlled zones.

Best for

Best for electricians and contractors specifying a simple wall-mounted control package for two-zone radiant heat systems. It suits projects where staff or homeowners want manual intensity adjustment plus timer-based shutoff without moving to a more complex custom control system.

Installed in

Typically installed in-wall in indoor or outdoor protected areas. The controller enclosure measures 4-1/2 in x 12-1/4 in x 2-1/2 in (approximately 114 x 311 x 64 mm), with a face plate size of 5-1/2 in x 13-3/16 in (approximately 140 x 335 mm). It requires 120V, 1A local power and is wired to the relay control panel using CAT5 or comparable low-voltage cable.

Why this product exists

This controller exists to give users practical zone-by-zone heat adjustment and automatic shutoff in larger radiant heating layouts. In trade use, separate zones are commonly used to match seating areas or occupancy patterns so heat is applied only where needed, which can help reduce unnecessary runtime. Actual energy use depends on heater sizing, layout, exposure, and operating habits.

Compared with similar products

Compared with a basic on/off switch, this model adds variable analog intensity control and a built-in digital timer. Compared with larger multi-zone packages, it is a better fit where only two zones are required. Each zone analog intensity control knob can control up to three relays in the compatible solid state relay panel, which is useful when multiple heaters operate together within one zone.
