Ademco Inc CT30A1005/E1 Heat Only Thermostat

Product Description

The ADEMCO INC CT30A1005/E1 is a mechanical heat-only thermostat designed for simple, low-maintenance temperature control in residential heating applications. It uses a bi-metal temperature sensor paired with a snap-action switch to provide reliable on/off control without electronic components or programming. The mercury-free design meets modern environmental standards. A decorative back plate is included for a clean wall finish. This thermostat is intended for installation by HVAC technicians or qualified service professionals on conventional heating systems only.

The CT30A1005/E1 is suited for residential spaces where a no-frills heat-only control solution is required. Its straightforward mechanical operation makes it a practical replacement or upgrade in single-stage heating systems such as gas furnaces, boilers, and electric baseboard systems that do not use a heat pump configuration. The economy design is appropriate for rental properties, light commercial spaces, or any installation where simplicity and reliability take priority over programmable features.
