Evohome HR92 new install bound message

Hi

I have 8 HR92 valves, 1 BDR and an Evohome Controller, so a simple install. All HRs are 1 HR to 1 zone.

Installing the first 5 HRs to the rads and binding to the controller seem to work with a simple message of binding successful.

However with the 6th install, when bound the message said “1 actuator bound 2-ways”.

I can find no help on the forum or the web as to what this message means.

Hoping someone understands this,

Stephen
