Help to install the Relay in a SIME Format Low NOx

Post by miguelayesan »

Daer all,

some days ago i bought a netatmo thermostat and i'm struggling to connect the relay.

The boiler brand is : SIME Format Low NOx

I attach a picture with the terminsla available and how i conected them...

• Terminals 5 and 6 ...where having a black cable connecting them..and are marked as TA ...so i suppossed that they are the thermostat terminsla...so i conected here the black and grey cables...

• I was not sure about which ones were the terminals for the power ...so i tried to connect the blue and brown cales to 4 and 3 first...But no light blinking in the relay....

... later i tried to connect them to the terminals 1 and 2 ...

But no sucess in any of the options ... the relay simply does not get iluminated ....(A white light is supposed to come, i undersood)

Could someone please help me on this? I'd really appreciate... we are very cold at home and would need to solve it asap.-..

:-)

Thanks a lot in adavance...



Miguel

Black and Grey to 5 and 6 (TA) should be correct.
However Brown and Blue need to be connected to a power source or added the boiler's power source.

The 3-4 (SE) terminals are for an external temperature sensor.
Home: Weather Station (V3 + Rain & Wind Gauge, 3 additional Indoor Modules, Shield), Valves Starter Pack + 7 Valves, Video Doorbell
Office: Thermostat (V2), Healthy Home Coach, Smoke Alarm, 2 2in1 Sensors
