Solid State Relay Panel · 2-Zone Control · Requires Analog Controller · Infratech 30-4052
What this product is for
This solid state relay panel is used to control two heating zones in an Infratech radiant heating system. It is intended for projects that need central relay switching with separate low-voltage analog control.
Use for
Use for Infratech patio and radiant heating installations where two independent zones are needed, such as seating areas, covered patios, hospitality spaces, or residential outdoor living areas. It is commonly used when the control package includes a matching analog zone controller.
Avoid for
Avoid for standalone heater control without the required analog controller, or for applications needing more than two zones from a single panel. Do not assume universal compatibility with non-Infratech heating systems unless the control design has been verified.
Best for
Best for electricians and contractors specifying Infratech solid state control packages for 2-zone layouts. Solid state switching is commonly selected where reduced mechanical wear and quieter operation are preferred over contactor-style control.
Installed in
Typically installed in residential and commercial radiant heating control setups, including patios, restaurants, hospitality venues, and covered outdoor spaces. The panel size is approximately 16 x 14 x 7 in. (406 x 356 x 178 mm), so allow practical wall space and service access during layout.
Why this product exists
This panel exists to provide dedicated relay control for two heater zones within the Infratech solid state control platform. It separates power switching from the user control interface, helping simplify multi-zone system design and coordinated heater control.
Compared with similar products
Compared with single-zone control options, this 2-relay panel supports two independently controlled heating areas from one enclosure. Compared with larger multi-relay panels, it suits smaller zone counts without oversizing the control package. As typical guidance, choosing the correct number of zones can help reduce unnecessary control cost and simplify wiring. Actual system design depends on heater load, voltage, layout, and local electrical code.
