TWO-ZONE MANAGEMENT WIRING DIAGRAM WITH
WIRELESS ROOM PROBES
When using wireless room probes, the jumpers on terminal
boards 40-41 and 57-58 must be maintained.
The operating mode of each zone must be set on the boiler zone
menu (see the boiler instruction book).
Furthermore, on these boiler models, the Dominus device can be
used together with the Wireless Room Probes control (optional).
