The PIERRE Wave - Radiator Valve (TRV) fits in place of the manual head on a radiator valve and drives the pin under system control, so each room can hold its own setpoint and follow its own schedule without additional wiring.
It holds temperature to ±1 °C using a built-in sensor, and self-calibrates on installation to find the pin travel of the valve it is fitted to.
It runs from two AA cells and reports low battery. Anti-frost and anti-limescale routines run automatically — the first holds a minimum temperature, the second exercises the pin periodically so it does not seize over summer. A child lock disables the local dial.
It communicates over PIERRE Wave (Zigbee 3.0, 2.4 GHz) and operates from -10 °C to +40 °C.
