4. INSTALLATION
4.3 Installation of electrical box for wiring
of high-temperature circulator pump
The electrical box for the wiring of the high temperature circulator pump
(not included standard) allows electrical connection of the circulator
pumps of the of high temperature zones with possible electro-thermal
heads with auxiliary micro: these (for parallel connection of the micros-
witches, in parallel see page 27), controlled by the room thermostat(s) for
the zone to which they are associated, isolate the related zone to prevent
passive circulation of the heat-carrying fluid and shut off the circulator
pump assigned to serve that zone.
For "First Box" in wall-mounted configuration (or installation directly on
the wall), install the electrical box for wiring of the high-temperature cir-
culator pump on the wall using suitable screws and plugs, using the holes
in the perforated strip located on the back of the box.
For "First Box" pre-assembled in the Metal Box, install the electrical box
for wiring the high-temperature circulator pump using the screws provided.
