All internal wiring is factory mounted.
The thermostat which controls the DHW temperature (1,
fig. 10) is adjustable between 20 and 65 °C. The built in
safety thermal cut out operates at 90 °C. Should the
thermal cut out be brought into operation, the
motorized 2 port valve will be operated and shut the
primary flow to the cylinder. Press the reset button (2,
fig. 10) to reset thermal cut out and motorised valve.
Important:
Before resetting the thermal cutout or changing
the temperatur setting of the thermostat, switch
off the electrical supply.
