Issue:
Verifying the ZB2 and ZB4 compatibility

Product Line:
22mm push button operators

Environment:
ZB4/ ZB5 22mm Harmony Push Buttons

Cause:
Determine if the existing ZB2 unit has to be completely replaced, or replacement parts are available.

Resolution:
No, the ZB2 operators can’t be used with the ZB4 contacts and light modules and the ZB4 operators cannot be used with the ZB2 contacts and light modules. The lines are both 22mm so the complete devices can be substituted.
