The presence of the jumper on the TA contact is required when the central heating / C.H. demand needs to be checked using
only CARv2.
Operation with external probe
It is possible to use the thermoregulation functions associated to an external probe.
The boiler is designed for use with an optional external probe.
With the external probe connected, the flow setpoint for room central heating / C.H. is managed by the system depending on the external
temperature measured (Par. 1.10).
It is possible to enable thermal adjustment for each individual zone. The symbol is present if the probe is connected and working.
If room probes are present, "Room temperature" appears displaying the reading of the zone room temperature.
If room probes are present, "Room Set" appears, showing the room set in progress.
Zone menu description/Information
• Operation status
- OFF = off;
- A-ECO = means that the zone is in the time slot where the central heating / C.H. has been programmed to be deactivated;
- A-COMF = means that the zone is in the time slot where the central heating / C.H. has been programmed to be activated and running
if the room thermostat is closed;
- MAN = central heating / C.H. is always active and the relative time program is not considered.
• Room thermostat status
- if open, there is no central heating / C.H. request in progress (until it is closed);
- if closed, it will go in combination with the boiler programming.
• Central heating / C.H. set
- info on the actual active set in real time (depends on the central heating / C.H. programming or any external probe).
