Fitting the electric actuator to the mixing valve:
12)
Remove the white plastic protection from the e-Cartridge.
Keep this for manual adjustment.
13)
Remove the black cap from the e-Cartridge
(see page 7)
and screw the mixed water
temperature probe (cable marked E) to the cartridge.
14)
Connect the cables marked E and C by clipping the RJ connectors to the actuator.
This must be done before screwing the actuator onto the e-Cartridge.
15)
Screw the actuator onto the e-Cartridge.
Tighten the floating nut (by hand only) until it stops.
16)
At this point, supply water to the system again.
Installing and connecting the programming control unit:
Provide a watertight cabinet appropriate to the location where the control unit is
installed to guard against splashing and a damp or corrosive environment.
17)
Unscrew and remove the cover from the programming control unit, then fix it to the wall.
18)
Connect cable C (red) to the programming control unit.
19)
Connect cable D (blue) to the programming control unit and position the external
probe on the pipe
(see pipe layout diagram on page 11)
using aluminium tape. Optional:
if probe D is not connected, the mixed water probe F is used to monitor thermal shock.
Connecting the relays (depending on the system):
20)
Connecting the alarm relay (figure on page 14).
21)
Connecting the
circulation pump
relay:
- For a system with closed loop (figure on page 14): if the circulator is being controlled
by a timer, wire the circulation pump relay in parallel with the timer.
- For systems with open loop (figure on page 14): connect the circulation pump
activation relay to the flush solenoid valve power supply. In this scenario, the system
does not include a circulation pump.
22)
Connect the
DHW production
relay if the hot water production temperature needs
to be increased for thermal shock cycles (figure on page 14).
23)
Connecting the
flush
relay:
- For systems with a recirculation loop (figure on page 14): connect the flush relay to
the flush valve power supply.
- For systems without a recirculation loop: the relay is not used, as the flush solenoid
valve is activated by the circulation pump relay
(see step 21 above)
.
24)
Connect the
power supply
(230 VAC 50 Hz).
