## Description

Install a Smart Thermostat Without a C-Wire. The C-Wire provides a path for continuous power to Wi-Fi thermostats, but often homes are missing this common wire. The C-Wire Power Adapter makes Honeywell Home smart thermostats compatible with most homes that don’t have this wire.

## Features

- BEFORE PURCHASING, check to see if the Wi-Fi thermostat you will pair with this adapter is compatible with your home and determine if your home needs a C-wire power adapter. The C-wire adapter should work for all applications in which the thermostat being replaced doesn't have a common wire and does have Y and G wires attached.
- The C-Wire Power Adapter makes Honeywell Home smart thermostats compatible with most homes that don’t have a common wire.
- Quickly and easily power connected thermostats that require a c-wire.
- Use for Wi-Fi, 24v Honeywell Home thermostats when a common wire is needed but not present. Note, your home may have an unused C-Wire that should be verified before purchasing this adapter.
- Easy push terminals and an adhesive mount make installation quick and easy.
- Simple adhesive mount allows you to attach the adapter to the outside of your furnace.
- Be discreet with a closed cover to conceal internal components and wires. The sleek, modern Honeywell Home exterior keeps the installation site clean and professional.
- COMPATIBLE WITH: Forced air (gas, oil or electric), hot water and steam, and heat pumps with electric backup. Does NOT work with electric baseboard heat (120-240V).
- NOTE: The C-Wire Adapter will work with multi-stage systems including heat pumps if your Wi-Fi thermostat will work with these systems; however, please follow the installation directions carefully to avoid disconnecting incorrect wires.

## Questions & Answers

**Q: Does this product need to be plugged into an AC outlet ?**
A: No, it has to be wired into the furnace!

**Q: Will this work with a 3 wire heat only forced air system?? My system only has red,white & green wires...Or can I just use the green wire as a common.**
A: Hi Rcq78, this C wire adapter requires 4 wires. If you have only 3 wires we recommend contacting your HVAC contractor to help you run a new wire from the C on your heating system to C on the thermostat. - Maria

**Q: Will this product work with a 2 wire system?**
A: Hi Marcella,  thanks for contacting us. Since your system has 2 wires only, we recommend checking on the furnace motherboard to see if there is a C terminal and run a new wire from that C to the thermostat on C. The other option will be to Install a second transformer that provides 24Volts. The adapter won't be compatible. Please, feel free to reach us at 1-855-733-5465. We'd be glad to assist you with further information. Thank you.

**Q: Can this me used in a dual application with 2 of the same thermostat’s. First floor and second floor?**
A: No, a Honeywell Home CWIREADPTR C-Wire Power Adapter will be required for each thermostat. -Jerry
