Replacing H37XL Heating Control with H3747

[Est_Pete]

Folks,
Replacing my H37XL with new H3747. Reason being that the H37XL had stopped signaling for the HW actuator to open.
Anyway, I wasn't paying close enough attention when I "woke up" the PTD. This resulted in it setting default configuration rather then addressing that I was replacing an old controller etc. Result is the receiver was set up incorrectly. I tried a factory reset with the PTD, but this didn't seem to communicate correctly with the receiver. Despite pressing and holding the channel button for 7 secs' etc. I thought something was up with the PTD, so I pressed and held the "wake up button" on the PTD. This resulted in it zeroing time and temp' display. Now I can't get anything to work.
Is any of this salvageable? Does anyone know how to reset the PTD, so I can start from fresh?
Any tips (other than read the instructions more closely appreciated.
Thanks.

Just skimmed through the instructions what happens if you long press the menu button in top?

Hello there. It attempts to connect with the receiver. But this fails as the receiver is not set for pairing. All attempts at setting the receiver to pair by holding the channel button for greater than 7 secs’ fails. I cannot get the red pair light to come on.
