Honeywell CT87K Thermostat Details

The Honeywell CT87K thermostat manual emphasizes crucial preparatory steps for safe and effective installation. Users are instructed to always turn off power to the heating system at the furnace or circuit breaker before commencing work, a vital safety measure. A specific mercury notice is included, advising proper disposal methods if an old thermostat contains this hazardous material, highlighting environmental responsibility. The package thoughtfully includes wire labels, wall anchors, screws, and an optional coverplate, ensuring users have the necessary components for a clean setup.

Installation proceeds with carefully labeling existing wires using the provided adhesive tags, corresponding to the letter designations on the old thermostat, rather than relying on wire colors. This meticulous labeling process prevents errors during reconnection. The manual then guides users through marking and drilling holes for the new thermostat's base, suggesting a level for aesthetic alignment. Once holes are prepared, the base is secured, and wires are carefully pulled through before connection.

Connecting wires involves matching the previously labeled wires to the corresponding terminals on the CT87K, ensuring a secure fit by loosening and tightening screw terminals. The manual provides explicit wiring instructions for 2-wire heat-only and 3-wire hot water heat-only systems, which are specific to the CT87K model. After wiring, excess wire should be pushed back into the wall, maintaining a tidy installation. The system requires setting internal cycle rate switches based on the heating system type (e.g., steam, hot water, gas, electric), a critical step for optimal performance.

Finishing the installation involves aligning the thermostat with its base and gently pushing it until it snaps into place, followed by restoring electrical power. Once powered, the CT87K's operation is refreshingly straightforward: users simply rotate the temperature setting dial to achieve their desired indoor temperature. The large, clear dial, characteristic of "The Round®" design, makes temperature adjustment intuitive and easy to read. This direct interaction highlights its user-friendly, non-programmable nature, focusing purely on maintaining a comfortable heating level without complex schedules.

The manual also details optional accessories that enhance the thermostat's utility and appearance. These include a decorative cover plate that can conceal unsightly wall marks from a previous thermostat or adapt mounting to an electrical box. Additionally, temperature range stops are available, providing an administrative control to limit the minimum and maximum temperature settings, which is particularly useful in public or rental properties. Should any issues arise, Honeywell provides comprehensive support, including a toll-free customer care line and website, offering guidance for installation or troubleshooting, and clearly outlining the terms of its one-year limited warranty.

Frequently Asked Questions (FAQs)

What type of heating systems is the Honeywell CT87K compatible with?

The CT87K is designed for 24 Vac heating systems, including 2-wire heat-only and 3-wire hot water heat-only systems.

What should I do before installing the CT87K thermostat?

Always turn off power to your heating system at the furnace or circuit breaker. You'll also need screwdrivers, a hammer, a pencil, and a drill with appropriate bits.

How do I properly dispose of an old thermostat containing mercury?

If your old thermostat contains mercury, contact your local waste management authority for proper disposal instructions.

How do I ensure I connect the wires correctly?

Use the wire labels provided in the package to mark each wire according to the letter designation on your old thermostat. Connect these labeled wires to the matching terminals on the CT87K base, ignoring wire colors.

What if my old thermostat has too many wires for the CT87K?

For the CT87K, if your old thermostat has 4 or more wires (not counting terminals C or C1), you might have purchased the wrong replacement thermostat. It's advised to call Honeywell Customer Care for advice.

How do I set the heat anticipator on the CT87K?

The heat anticipator indicator needs to be set by matching the setting from your old thermostat or using the provided chart, which specifies values based on your heating system type (e.g., Steam 1.2, Electric Heat 0.3).

What are the cycle rate switches for and how do I set them?

The cycle rate switches (Switch 1 and Switch 2) are internal settings that optimize the thermostat's performance for different heating system types. Refer to the manual's table to set them correctly for your system (e.g., "Steam or gravity" is On/On, "Gas or oil warm air" is Off/Off).

Can I limit the temperature range on the CT87K?

Yes, optional temperature range stops (Model 50010944-001) can be installed on the back of the thermostat to limit the minimum and maximum temperature settings.

What is 'The Round®' design?

"The Round®" is Honeywell's registered trademark for its classic, circular thermostat design, known for its intuitive temperature setting dial and simple aesthetic.

What is covered by the 1-year limited warranty?

The warranty covers defects in workmanship or materials under normal use and service for one year from the purchase date. Honeywell will repair or replace defective products at its option. It does not cover removal/reinstallation costs or damage caused by the consumer.
