The PIERRE Wave (Zigbee 3.0, 2.4 GHz) system consists of the following components.

Required

1. PIERRE Wave products: switches, modules, sensors, thermostats and other devices. They connect wirelessly to the gateway.
2. Gateway: a PIERRE display and/or gateway. It links all PIERRE Wave devices and handles the communication with the app.

Optional

1. Smart PIERRE app: control and monitoring from a smartphone or tablet. Not required for basic operation.
2. Router: gives the gateway internet access for remote control.

Operation: the gateway connects to the router by Wi-Fi or LAN. PIERRE Wave products communicate wirelessly with the gateway in both directions: commands are sent and status updates are received through the Smart PIERRE app.

Open window function

If an open window causes the room temperature to drop by more than 6 °C within 4 minutes, the screen shows "OP" and the valve closes. The state is cleared when the room temperature rises by 3 °C, automatically after 48 minutes, or manually.

Anti-scale function

If the valve stays partially closed or unused for a long time, deposits can block it. To prevent this, the valve head fully opens the valve every two weeks for 30 seconds. During this cycle the screen briefly shows "Ad" and then returns to normal operation.

Child lock function

To prevent accidental adjustments by children, activate the child lock function by pressing and holding the button when the device is powered on. The screen will show "LC" to indicate activation. To unlock, simply repeat the activation process.

Anti-freezing

When the valve is switched off ("OFF" on the screen) the anti-freeze function is active: the valve opens when the room temperature drops below 5 °C and closes when it rises above 8 °C.

Low voltage warning function

When the battery voltage is too low, an alarm symbol will appear on the display to remind the user to replace the battery.

Temporary mode

When in programming mode, if you want to manually change the temperature of the current programming period, turn the knob to adjust the desired temperature, which will be maintained until the end of the current programming period.

Press down on the bottom cover and unscrew it to the right.

Press and hold the battery sheet and push it out, placing the battery in the compartment.

NOTE

Insert the battery according to the "+" and "-" marks in the battery compartment.

The screen shows "LA".

Set the temperature to the maximum of 35 °C (when the top bar is flush with the bottom).

1. Valve head at fully open position

Rotate and tighten the copper ring of the valve head onto the thread of the radiator valve.

Note: if the valve connection does not match the valve head, install the matching adapter first (see Accessories).
