1.5  REMOTE CONTROLS AND 

ROOM TIMER THERMOSTATS 

(OPTIONAL).

The boiler is prepared for the application of room 

chronothermostats or remote controls, which are 

available as optional kits (Fig. 1-3).

All Immergas timer thermostats are connected 

with 2 wires only. Carefully read the user and 

assembly instructions contained in the acces-

sory kit.
• On/Off digital chronothermostat. The timer 

thermostat allows:

  - to set two room temperature values: one for 

day (comfort temperature) and one for night 

(lower temperature);

  - to set up to four on/off differential weekly 

programs;

  - to select the required operating mode from 

the various possible alternatives:

  • permanent functioning in comfort temp;

  • permanent functioning in reduced temp;

  • permanent functioning in adjustable anti-

freeze temp.

  The timer thermostat is powered by two 1.5V 

LR 6 type alkaline batteries.

• Comando Amico Remoto

V2

 Remote Control 

Device (CAR

V2

) with climate timer thermostat 

function. In addition to the functions described 

in the previous point, the CAR

V2

 panel enables 

the user to control all the important informa-

tion regarding operation of the appliance and 

the heating system with the opportunity of eas-

ily intervening on the previously set parameters 

without having to go to the place where the ap-

pliance is installed. The panel is provided with 

self-diagnosis to display any boiler functioning 

anomalies. The climate chronothermostat in-

corporated into the remote panel enables the 

system flow temperature to be adjusted to the 

actual needs of the room being heated, in order 

to obtain the desired room temperature with 

extreme precision and therefore with evident 

saving in running costs. The timer thermostat 

is fed directly by the boiler by means of the 

same 2 wires used for the transmission of data 

between boiler and timer thermostat.

Important:

 if the system is subdivided into zones 

using the relevant kit. the CAR

V2

 must be used 

with its climate thermostat function disabled, i.e. 

it must be set to On/Off mode.

Comando Amico Remoto remote control

V2

or On/Off timer thermostat electrical con-

nections (Optional).

The operations described 

below must be performed after having removed 

the voltage from the appliance

. Any thermostat 

or On/Off environment chronothermostat must 

be connected to clamps 40 and 41 eliminating 

jumper X40 (Fig. 3-2). Make sure that the On/

Off thermostat contact is of the “clean” type, i.e. 

independent of the mains supply, otherwise the 

electronic adjustment card would be damaged. 

Any Comando Amico Remoto

V2

 remote control

must be connected to clamps 40 and 41 elimi-

nating jumper X40 on the circuit board, paying 

attention not to invert the connections (Fig. 3-2).

Important:

 if the Remote Friend Control

V2

, 

remote control

V2

 or any other On/Off chrono-

thermostat is used arrange two separate lines in 

compliance with current regulations regarding 

electrical systems. No boiler pipes must ever be 

used to earth the electric system or telephone 

lines. Ensure elimination of this risk before mak-

ing the boiler electrical connections.

1.6  EXTERNAL PROBE (OPTIONAL).

The boiler is prepared for the application of the 

external probe (Fig. 1-4), which is available as an 

optional kit. The probe can be connected directly 

to the boiler electrical system and allows the max. 

system flow temperature to be automatically de-

creased when the external temperature increases, 

in order to adjust the heat supplied to the system 

according to the change in external temperature. 

The external probe always acts when connected 

independently from the presence or type of room 

thermostat used. The correlation between system 

flow temperature and external temperature is de-

termined by the position of the selector switch on 

the boiler control panel according to the curves 

shown in the diagram (Fig. 1-5). The electric con-

nection of the external probe must be made on 

clamps 38 and 39 on the boiler P.C.B. (Fig. 3-2).
