This is an unused example. The packaging has a bit of squashing and damage however so I removed it to check it was working. As you can see it is. Please note the paperwork is absent, the remaining contents are in new condition. The RF link will only be established once the RF unit is inserted. Please ensure you have a compatible boiler prior to purchase. I have a couple of these available, both are in the same condition. Since it is well protected within the packaging I will likely post it as is in a plastic mailing bag or similar. Just let me know when ordering if you require additional or alternative packaging.
