Ademco Inc CT87N1001/E1 Round Heat Cool Thermostat

Product Description

The ADEMCO INC CT87N1001/E1 is a round, mercury-free thermostat designed for residential heating and cooling control. It uses classic round styling with a decorative cover ring that conceals wall marks left by previous thermostat installations. The unit delivers precise temperature control across standard heating and cooling systems, including heat pumps operating without auxiliary heat. Licensed HVAC technicians install this thermostat as a straightforward replacement in residential applications where a clean, reliable mechanical thermostat is preferred over a programmable or digital unit.

This thermostat is suited for residential HVAC installations requiring dependable heat-cool switching. Its round form factor and cover ring make it a practical choice when upgrading or replacing older round thermostats on standard walls. It is compatible with heat pump systems that do not rely on auxiliary or emergency heat stages, making it appropriate for single-stage heat pump configurations in homes and light commercial spaces. The mercury-free design meets current environmental standards for thermostat disposal and replacement.

Installation Notes

A licensed HVAC technician should power down the system at the breaker before removing the existing thermostat and wiring the CT87N1001/E1. Low-voltage thermostat wiring typically falls under NEC guidelines, and local codes may require a licensed installer. Verify that the existing system does not rely on auxiliary or emergency heat stages before installing this unit, as it does not support those configurations. Mount the thermostat level on an interior wall away from direct sunlight, drafts, and heat sources for accurate temperature sensing.
