6.13.3 Post-heating resistors modulating
To use the modulating resistors set the parameter PG06 = 3.
In opening the output remains at 0% as long as the request does not become greater than the parameter PB25, then
takes the value of the request. In closing, the output takes the value of the request until it is greater than PB25, then
is maintained at the value of PB25 until the request does not go to 0%.
6.13.4 Resistance in summer
You can use the resistance as an aid in midseason.
In this case the adjustment parameters follows PB23 and PB24.
6.13.5 Status of post-heating heating elements
Each of the three stages of the heating elements can assume one of the following operating states:
1. Disabled: the stage of the heating element is not managed by the controller. While in this status you will see
the symbol “---” in the user interface.
2. Off: the stage of the heating element is off. In the user interface you will see written “ON” when in this
status “OFF”.
3. Waiting for Start-up: the stage of the heating elements is about to switch-on, and is in queue for a protection
timetable. In this status in the user interface you will see written (and flashing) “WON”.
4. Waiting for shutdown: the stage of the heating elements is about to shutdown, and is in queue for a
protection timetable. In this status in the user interface you will see written (and flashing) “WOFF”.
5. On: the stage of the heating elements is on. In the user interface you will see written “ON” when in this state
“ON”.
6. Alarm: the heating elements are blocked as a result of the relative thermal alarms. In the user interface you
will see written “ALARM” when in this state.
