Product Information
Full details
The Honeywell Thermostat (T87/Y87) is a versatile digital room thermostat designed for modern homes, offering precise temperature control for direct boiler operation or as part of a multi-zone system. It excels in providing reliable room temperature measurement and setpoint adjustment, with the key benefit of optional connected operation via a Honeywell RFG100 internet gateway for remote smartphone control. A potential caveat is that the RF models require 2 x AA batteries, which need periodic replacement.

FAQs
What type of batteries do the RF models use?
The RF models use 2 x AA alkaline batteries.
Can I control this thermostat remotely?
Yes, you can control it remotely via a smartphone or tablet if you have the Honeywell RFG100 internet gateway connected.
Is this thermostat compatible with my existing boiler?
The T87/Y87 is compatible with most boilers, including those with modulating (OpenTherm(R)) or on/off controls.
How do I clean the thermostat?
Wipe the thermostat with a dry or slightly damp soft cloth. Avoid harsh chemicals or abrasive cleaners.
What is OpenTherm(R)?
OpenTherm(R) is a communication protocol that allows for modulating control of your boiler, meaning it can adjust its heat output more precisely to match demand, leading to greater efficiency.
Can this thermostat be used in a multi-zone heating system?
Yes, it can be used as the room unit in a multi-zone system when paired with compatible zone controllers like Honeywell's Evohome or HCE80.
What is the wireless frequency used by the RF models?
The RF models operate on the 868MHz frequency for enhanced security and reliability.
Troubleshooting
Thermostat not powering on (RF models)
Ensure the 2 x AA alkaline batteries are correctly inserted and have sufficient charge. Replace batteries if depleted.
Heating system not responding to thermostat
Verify wiring connections for wired models. For RF models, check the wireless link to the zone controller and ensure they are within range. Confirm the thermostat is set to the correct operating mode (Heat/Off).
Inaccurate room temperature readings
Ensure the thermostat is not located near heat sources (radiators, direct sunlight) or drafts. Check that air vents on the unit are clear of dust and obstructions.
Unable to connect to the internet gateway
Confirm the RFG100 gateway is powered on and connected to your home network. Check your Wi-Fi signal strength and reboot both the gateway and your router if necessary.
App not showing correct status
Ensure your smartphone has an active internet connection. Try refreshing the app or logging out and back in. Verify the RFG100 gateway is online.

Setup, Compatibility & Care
Setup: Installation varies between wired and RF models. Wired models require connection to the heating system's control wires. RF models require pairing with a compatible zone controller (e.g., Evohome) and setting up the optional internet gateway (RFG100) for connected features. Follow the specific installation manual for your model and system.
Compatibility: This thermostat is compatible with most boilers, including those using OpenTherm(R) (modulating) or standard on/off controls. It integrates with Honeywell's Evohome and HCE80 zone controllers for multi-zone applications.
Care: Keep the thermostat clean by wiping it with a dry or slightly damp soft cloth. Avoid using abrasive cleaners or solvents. Ensure vents on the unit are not obstructed to maintain accurate temperature readings. For RF models, replace the 2 x AA alkaline batteries when indicated by the low battery warning.
