I have this CL4-GSM 3 years ago and everything works great; But I have a question.
Is there any way that the CL4-GSM does not store the messages in the chip and deletes them automatically?
Because I have to constantly remove the chip to transfer it to a cell phone and delete the messages; This is because it reaches 25 messages stored in the chip and the equipment crashes.
Then it does not work again until the messages on the chip are deleted.
And every 1 week I have to remove the chip, transfer it to a cell phone to delete the messages and reinstall it in the CL4-GSM.
Thanks

Will this work on this AC: klimatizacija.hr/fujitsu-standard-eco-inverter-34-kw-proizvod-1659/
Or is it better to use CL2 controller?

I purchased this but for some reason there is no connection. The light flashes and i do everything exactly like in your video, but it just does not work. Could it be because my SIM-card supports 3G? Or some other reason?

+Madis Metsalu Hey Madis. Sounds like that could be the problem, it seems that this only supports Band GSM 850/900/1800/1900MHz

[@madismet1]

+Banggood Thanks for the reply. These bands are used here (in Estonia) as well - all current SIM cards support them. Could the problem be that the device requires a non-USIM card, i.e. a 2G-only SIM card? I think these have been phased out here, all SIMs support at least 3G, as well as 2G.
