Controls rotation
Every hour the order of ignition of triac G1÷G4 controls is rotated in such a way to partition
evenly in time the use of all heating elements.
CONTROL OF EXTERNAL PROBE
Installation and functioning at sliding temperature
For the connection of the External Probe, it shall be used the Original Kit
FIAMMA code F.532 provided in the accessories of the electric boilers
Elektra. The electrical connection shall be done in the external terminal at
the general electric panel already prearranged in the standard cabling of
the boiler. The connection must be carried out with junction cables and wires having a
minimum section of 1,5 mm and, if possible, avoiding the insertion along with electric lines,
digital lines of inverter or other not compatible.
After the connection the external probe must be enabled by means of the introduction of a
variation of P1 parameter, changed from 0 to 1.
Then the setpoint chased by the heating delivery probe will be calculated as follows:
T
ch
[°C] = [( T
room
[°C] – T
ext
[°C]) * dc/10 ] + T
room
[°C]
T
ch
: heating setpoint calculated by the system
T
room
: ambient temperature set by the user
T
ext
: outside temperature measured by the probe
dc: dispersion coefficient of the building can be set by parameter P2.
