External Probe Kit

Installation and setting

The External Probe automatically manages the system delivery temperature according 
to the external temperature, so that the user does not have to adjust it manually. This 
function is also defined 

"sliding temperature"

.

** 

i.e. heating elements temperature. This adjustment does not have to be confused with ambient temperature (settable 

on ambient thermostat or on remote control, but not on boiler) which does not depend from the first one.

Installation must be carried out by a qualified technician 

following the instructions 

supplied with the kit. For connection to management board see "Boiler electric diagram:" 
on page 16. 
After having installed the external Probe, keys

 and

 described in the User 

Section will not allow setting the delivery temperature any more, but the dispersion 
coefficient 

"kd"

, e.g. the influence that the external temperature, detected by the 

probe, will have on the system delivery temperature, as shown in the following diagram.

ENG 00

the 

kd

 value must be adjusted according to the estimated quality of the 

property thermal insulation . Its range of adjustment will be from 01 to 30:

the 

highest values

 are used when there is a 

high thermal dispersion

 and therefore 

a 

less efficient insulation

 (and vice versa).

  Given the great variety of property types, it is not possible to give precise 

indications on the 

kd

 value to set. 

a correct adjustment will have to be 

evaluated case by case and will result in best comfort in all weather 

conditions 

 which require heating, i.e. a quick achievement of ambient 

temperature at cold climate conditions and absence of overheating at mild 
climate.

external Probe Kit with optional remote control

If Remote Control was present, its 

 P04

 parameter (remote ambient modulation type) 

must be set on value 

 2

 (modulating on external probe and on-off on ambient probe) 

or

 3 

(modulating on both ambient and external probe) as described in 

paragraph 5

 of the 

booklet supplied with the Remote Control Kit. Therefore, also the 

kd

 has to be set on this 

last one (ref. 

paragraph 8 .6

 of the same booklet). On the Remote Control, only because 

of a display difference, the 

kd

 range of adjustment will be 

0.1...3.0

 instead of 01...30.

Remote Control Kit

The original Remote Control 

is more 

than just a chronothermostat: 

it optimizes boiler operation

, 

interfacing with the relevant electronics. 
It incorporates a 

complete weekly 

climate programmer, easy to be set 

and used

: to switch from programmed 

to manual operation and vice versa it is 

enough to press a key

. It responds to 

all boiler controls

 and provides the 

Technician with 

diagnostic information and further functions

. Easy to install, it is 

connected in place of the Ambient Thermostat. It is powered by the boiler, in very low 
tension and therefore 

needs no batteries

.

  Remove Remote Control from its box and 

keep relevant instructions for use . 

attach them to this instruction 

booklet .

  neither the remote control 

nor the relevant cable coming 

from the boiler must be 

connected to the 230 V power 

supply, for no reason .

  In order to avoid malfunctions 

caused by disturbances, Remote Control connections and other possible low 
voltage connections must be kept separated from power supply system cables, 
e.g. letting them pass through separate sheaths.

Cable maximum length must be less than 50 m.

  The Remote Control must 

be installed at a height of 
approximately 1.5 m in a suitable 
location for measuring ambient 
temperature correctly, avoiding 
installation in recess or corners, 
behind doors or curtains, and 
install away from heat sources, 
direct sunlight and water sprays.

1 . 

Make sure that boiler is not electrically powered;

2 . 

install device as described in 

paragraph 4

 of the booklet supplied with the Kit;

3 . 

connect Remote Control connections to the "Ambient Thermostat - Remote Control" 
cable coming from the boiler using a suitable bipolar terminal. See also "Boiler 
electric diagram:" on page 16;

Note:

 Remote Control connection has no polarity.

  Check device correct operation. Electronics automatically recognises it (otherwise 

alarm 

E31

, already described in par. "Alarms - boiler shut-down" on page 

33 is triggered 

provided that

: 

•

on boiler control panel, through key 

, 

Summer

 mode is always selected. 

From now onwards, boiler operation modes (also OFF) will be selected only by 
the Remote Control;

•

board is set as in "Settings on electronic board" on page 33.
