The Navien Smart Plus NCR10-RW is a wireless room thermostat paired with the BCM41-RW WiFi receiver, giving Navien Blue Flame oil and NCB gas boiler installations full app-based heating control. The two devices communicate over a dedicated 868MHz two-way radio frequency (RF) link, while the BCM41-RW connects to home Wi-Fi to enable the Navien Smart Plus app, weather-based forecasting, and location-aware geofencing. Fitted alongside a compatible Navien boiler, the Smart Plus control raises the system's ErP efficiency rating from A to A+.

Compatibility
The NCR10-RW and BCM41-RW are designed specifically for integration with Navien NCB gas combi/system boilers and LCB Blue Flame oil boilers. Confirm your boiler model is listed as Smart Plus-compatible before ordering; the receiver's DIP switch settings differ by boiler range (NCB-CE and LCB700 boilers use a specific configuration, detailed in the installation manual).
How It Works
The BCM41-RW mounts near the boiler and links to it directly, then talks wirelessly to the NCR10-RW thermostat placed anywhere in the home. Once the receiver is connected to a home Wi-Fi network, the Navien Smart Plus app unlocks remote control, smart weather forecasting (via OpenWeatherMap), and geofencing that adjusts heating automatically based on the occupant's proximity to the property.
Why This Control
Wireless Room Thermostat Placement
The NCR10-RW requires no wiring back to the boiler, so it can be sited anywhere in the property — typically the room where the household spends the most time — for the most representative temperature reading.
Smart Weather Forecasting
When connected to Wi-Fi, the system checks live forecast data and adjusts heating output in advance of changing outdoor conditions, so the property stays comfortable without wasting energy heating for weather that doesn't arrive.
Geofencing
Using the smartphone app, the system can detect when the last household member leaves or is returning home and adjust the heating schedule automatically — supporting multiple users on a single system.
Raises System Efficiency to ErP A+
Fitted alongside a compatible Navien boiler, the Smart Plus control lifts the overall system ErP rating from A to A+, improving the property's EPC-relevant heating efficiency figures.
3-Zone Ready
Combined with the Smart Plus Control Pack (wiring centre and additional receivers), the system supports control of up to 3 heating zones from a single app.
Clear On-Screen Display
The thermostat's screen shows current room temperature, set temperature, operating mode, and programme information at a glance, without needing to open the app for routine adjustments.

Frequently Asked Questions
Does this control work with any boiler, or only Navien models?
The NCR10-RW and BCM41-RW are designed specifically for Navien NCB gas and LCB Blue Flame oil boilers. They are not a universal thermostat and should not be assumed compatible with other manufacturers' boilers.
Do I need a Wi-Fi connection for this to work?
Basic wireless room thermostat control between the NCR10-RW and BCM41-RW works over the 868MHz RF link without Wi-Fi. However, remote app control, Smart Forecast weather compensation, and geofencing all require the receiver to be connected to a home Wi-Fi network.
How many zones can this system control?
As supplied, this listing provides single-zone control. Up to 3 zones can be managed from one system when combined with the separately available Smart Plus Control Pack and additional wiring centre.
What batteries does the thermostat use?
The NCR10-RW wireless thermostat is powered by 2 x AA alkaline 1.5V batteries, supplied in the box.
Will this control improve my boiler's efficiency rating?
Yes. Navien state that pairing a Smart Plus control with a compatible Navien boiler raises the system ErP rating from A (92–93%) to A+ (98%).
Can I install this myself?
The receiver connects into the boiler's low-voltage control wiring, so installation should be carried out or checked by a Gas Safe registered engineer as part of a boiler installation or service visit, particularly where DIP switch configuration for the specific boiler model is required.
