ATTENTION! Do not install the socket under the housing of the
boiler or near hot pipes because it may damage the parts of the
device or compromise wireless (radio-frequency) connection.
WARNING! Modifying the socket can cause electric shock or
product failure.
Plug the COMPUTHERM Q1RX device into a power socket near the
location of the device to be controlled. A few seconds after the LED
lights of the device flash once, the device becomes ready for operation.
After this, you can start tuning the socket and the thermostat(s) (or the
socket, the receiver of the thermostat and the thermostat) together.
