3.6 Installing a DHW storage tank Sanit (Optional)
The procedure for suitably connecting a Sanit DHW tank to the Evolution EV HFC boiler is as
follows:
- Unplug the boiler from the mains.
- Connect a DHW temperature sensor (supplied optionally) to sensor terminal strip
J3
(terminals
16 and 17), first removing the resistance ( Ra ) supplied by default (see “Electrical Connection
Diagram").
- Insert the temperature sensor bulb in the bulb-holder sheath provided on the hot water tank.
- Connect the hot water tank feed pump to the supply terminal strip
J2 (BV; terminals N and 5)
see “Electrical Connection Diagram").
For correct hydraulic installation, carefully follow the assembly and connection instructions
enclosed with the hot water tank.
3.7 Anti-legionella function (with hot water tank only)
The Evolution EV HFC boiler allows the activation of the legionella prevention function for The
Evolution EV HFC boiler with a Sanit hot water tank installed has a legionella prevention function
that can be enabled for the domestic hot water in the tank.
This function must be activated by sufficiently qualified personnel. The function is enabled by
changing the boiler model selectors on the display card inside the control panel.
Before carrying out any work on the inside of the boiler, unplug it from the mains. To activate the
anti-legionella function, remove the top cover of the boiler then remove the lid of the control panel
box using a screwdriver to remove the two screws holding it in place. When this cover has been
removed, the electronic circuit board of the display, containing the programming switches, can be
accessed.
Select the anti-legionella function by turning selector 4 to ON (see "Electrical Diagram").
3.8 Installing the SRFC2/EV Underfloor Heating Kit (Optional)
The procedure for suitably connecting the SRFC2/EV Underfloor Heating Kit to the Evolution EV
HFC boiler is as follows:
- Unplug the boiler from the mains.
- Connect a flow temperature sensor (supplied with the kit) to sensor terminal strip J3 (terminals
15 and 16), first removing the resistance ( Rr ) supplied by default (see “Electrical Connection
Diagram").
- Fit the temperature sensor bulb according to the instructions enclosed with the kit.
- Connect the heating pump to supply terminal strip
J2 on the circuit 1 pump connection (pump
BC
1
; terminals N and 7) (see “Electrical Connection Diagram").
- Connect the PWM
C
cable to sensor terminal strip
J3
(terminals 13 and 14) (see “Electrical
Connection Diagram").
- Connect the 3-way mixer valve motor to supply terminal strip
J2
(terminals N, 8 (+) and 9 (-))
(see “Electrical Connection Diagram").
For correct hydraulic installation, carefully follow the assembly and connection instructions
enclosed with the SRFC2/EV kit.
