Remote Control Kit
This remote control is
more than a simple room thermostat
.
Thanks to this, it is possible to
manage the boiler in all its set-
tings like DHW and CH temperature adjustment,
boiler reset
in
case of boiler block, and of course it works as a
room thermo-
stat
both in
manual
and
weekly program
mode. It’s powered by
the boiler (in safety low voltage), so
it doesn’t need batteries.
Extract the Remote Control from its package.
Keep the
relevant user instruction booklet and annex it to this
Manual.
Nor the Remote Control neither the relevant cable coming
from the boiler must not, for any reason, be connected to
the 230Vac supply mains.
To avoid malfunctions due to electrical noise, the Remote
Control connections, as well as all low-voltage connections,
should be kept separated from power supply cables, e.g. by
enclosing it into separate raceways.
The maximum overall cable length shouldn't exceed 50 m.
1.
Cut off electricity from boiler;
2. install the device as described in the
paragraph 4
of the supplied instruction booklet;
3.
link the Remote Control wirings to the "Room Thermostat - Remote Control" cable coming out of
the boiler, by means of a suitable bipolar terminal. See also "Electrical diagram" on page 49;
Note: The Remote Control link is not polarized.
4. power supply the boiler; turn the boiler's Summer/Winter knob
on Summer otherwise the
Remote Control doesn't work and the boiler goes into alarm
31
described below;
5.
check the correct work of the device. The electronics should recognize it automatically.
Hereafter, the Summer/Winter knob should be left on Summer
; the boiler work is man-
aged by the Remote Control, including the OFF, Summer and Winter modes, and the technical
functions (such as several additional functions).
