CONTROL OF EXERNAL 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 N°1 parameter, changed from 0 to 1.
Then the setpoint chased by the heating delivery probe will be calculated as follows:
Ti = [ (Troom – T e) * K e / 10 ] + Troom
Example of calculation for several values of Ke
The coefficient Ke is the leakage of the building and it can be set by N°2 parameter.
Te, is the temperature measured by the external probe.
Troom is the setpoint related to the desired room temperature.
