The “LEM RF” room probe is an element of the “Proair System”. When installed it reads room temperature and humidity threshold and sends the readings to the “Polaris 3X/4X” control unit.
It can be mounted very quickly on the wall thank to the push-on template which will allows you to remove the element from the wall at any time just by exerting a slight external pressure.
The “LEM RF” room probe replaces the chrono-thermostats of the ProAir system, except for the master one. The probe is configured and set directly from the “Polaris 3X/4X” control unit, from the master chrono-thermostat or app (if applicable).
A blue flashing led located on the front will advise which is the zone connected with the room probe. All the operation must be done from the Master chrono-thermostat or from the control unit.
The RF transmission signal at 868 MHz guarantees that the information is sent to the “Polaris 3X / 4X” control unit with maximum coverage and speed. The “LEM RF” room probe, powered by two 1.5V AA batteries is available just in lumix white.
N.B.: the “LEM RF” room probe cannot be a Master but it can only be a slave. To control your ProAir System you must need a “Stealth 2X” or a “Discovery 2X” chrono-thermostat.
