GENERAL
OPERATION WITH REMOTE CONTROL (OPTIONAL)
The boiler can be operated with a RC03.54 remote control.
The RC03.54 remote control is an intelligent hourly programmer complete with ambient sensor suitable for adjustment and
control of wall-mounted gas boilers for heating and production of sanitary hot water mainly for installation in residential
buildings.
With the remote control connected to the boiler, the controls are divided as follows:
Controls on control panel:
- Operating mode selector: OFF/SUMMER/WINTER
- Parameter setting menu
- Reset (see “LOCK/RESET on page 58)
The following controls are managed by the remote control:
- Sanitary water temperature setting
- Delivery temperature setting.
If communication is interrupted or the remote terminal is disconnected, the system continues operating for a certain
time with the same setting as before the interruption waiting for communication to be re-established (“communication
timeout”).
If communication is not re-established after the timeout, the system goes into normal operating mode as if the remote
control were not connected, resuming all the controls.
As well as the programming function the remote control also allows:
- Setting and displaying the parameters
1
Boiler model - 0 Fast with plates - 1 Bithermal - 2 Water heater - 3 Water heater
2
Gas type selection - 0 Natural gas - 1 LPG
3
Maximum heat output: Range 0-100% (preset to 100%)
4
Heating restart timing: Range 0-20 = tmin 0-10 (preset to 4 = 2 min)
5
Ignition power: Range 0-75% (preset to natural gas 40% and LPG 35%)
6
Heating temperature adjustment range (preset to 1=30 - 83°C). Range 0=30 - 45°C (floor heating)
7
Heating pump post-circulation time setting: Range 0-20 (0-10 minutes)(Preset to 4 = 2 minutes)
8
Anti-Legionella function activation with boiler/water heater: 1 active, 0 inactive (preset to 1)
9
Activation/deactivation of the test function: 1 Active; 0 Inactive (preset to 0)

The remote control is connected directly to the board as shown in the connection diagram.
Electrical characteristics of the communication line:
Number of wires:
2 to be connected to the TA contacts (ambient thermostat)
Cable type:
bipolar (*)
Maximum line length:
50 metres
Maximum cable resistance:
2x5Ώ
Polarity:
no polarity.
(*) In environments with high electrical noise, a screened or twisted cable must be used.
