DIP-SWITCH SETTING
Turn off the power to the unit. This
operation should be carried out in the
installation phase, by suitably trained
and qualified personnel only.
The dip-switches are on the electronic
board.
**Warning: if the thermostats are
inserted in systems with Centralised
Control or Supervisor (e.g. VMF-E5),
it is necessary to set: Dip1=ON and
Dip2=OFF. The setting takes priority
over the presence of the valve and the
position of the probe.
