- Page 15 CONTROL OF MAIN HEAT EXCHANGER According to the required power during the heat request, the controls G1-G4 related to the main exchanger are turned on all or partially. The actuation of each control is reduced to a lapse of 4 seconds. Higher is the required power, more the control will remain operative in this lapse.
- Page 16 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.
- Page 17 ANTIFREEZE FUNCTION In case the delivery probe measures a temperature lower than 7°C, the circulator is activated. If the temperature goes down the value of 4°C the main heat exchanger is ignited until the delivery temperature has reached 20°C. The antifreeze function is active also with the boiler turned OFF (function in standby mode but with bright switch on).

- Page 19 HEATING REQUEST As the contact of room thermostat closes, if the mainboard is in winter mode, the system pump is only activated if the temperature of the primary heat exchanger is higher than the temperature set by parameter N°6. If the value of temperature measured by the primary heat exchanger probe is lower than the programmed delivery setpoint, the triac are ignited in sequence as per the required power.
- Page 20 “Heating elements status” The dashes located in the upper part indicate the heating elements status. Each dash corresponds to a 2 kW element. The first 6 dashes refer to heating modules of primary heat exchanger. “Heating request” When an heating request occurs, the temperature measured by the delivery probe is I I I I displayed and the symbol starts to flash.
