Can I link two relays to operate from the same button

Dont know for certain, but it is likely if configured in the learning process.

Can’t program relays separately. Very poor programming instructions. Provide please more detailed programming. Thanks

They can be programed seperatly but you cant have one toggled and one momentarily...dont know why...just cheap rubbish i suppose

What type of plug do I need to connect the unit to the mains in uk?

This unit must not be plugged directly into the mains. It works via a power pack which will need to have a D.C. output of suitable voltage (presumably 12 to 24v) There was a suitable power supply within my door closing unit, so I utilised this. Hope this helps.

what is the range of the remotes?

In my experience the range is between 3m and 6m varies between fobs.
