The Room Thermostat on Your Navien Boiler

The room thermostat tells the boiler when to provide heat. A failed or miswired thermostat causes no heat, constant heat, or erratic temperatures, and a smart thermostat upgrade can improve comfort and efficiency.

On Navien systems — including models such as NCB-240E, NCB-210E, NHB-150 — a failing room thermostat often shows up as e003 ignition failure or related symptoms. We diagnose it precisely and install the correct genuine Navien part.
