try covering zone 1 pir up set it as normal see if it arms or link zone 1 out you are going to make a bit of racket either way ? or by any chance is it above any sort of radiator or heat source ? i had that in the past years ? vents also
yes it has worked but only if zone 1 ( exit/entry) is not open/active when alarm is set. zone 1 is entry/exit.
man is coming over this week to change the mode from entry to timed...
You can change the programming of the PIR zone to e/e and the arming mode to timed and that should get rid of your issue, but find it hard to believe a pro wouldn't have changed it to that after the home owner refused to have a contact on the door for what ever reason so at least it would have worked.
