6.4 SANITARY HOT WATER (S.H.W.)
The CMX15 and CMX18 boilers have a mixed function of modulated heating and the preparation of sanitary hot
water. The S.H.W. function has priority over the heating and so the outputs are never added together.
A 50-litre header tank lagged with CFC free insulation accumulates the sanitary hot water.
6.4.1 AJUSTING THE S.H.W. TEMPERATURE
To switch on the S.H.W. push the
button. This function can be switched off by pushing the same button (the
display will only show a small red dot).
When the S.H.W. is switched on, the display will show the actual temperature in the S.H.W. accumulation tank.
The setting of the S.H.W. temperature can be modified by pushing both the
button or the
button and
adjusting the setting that flashes on the display. The modfied setting will be stored automatically afer a few seconds,
or instantly if we push the
button.
The S.H.W. setting can be varied between 20 and 55°C.
6.4.2 SANITARY HOT WATER SAFETY
OVERHEATING OF THE S.H.W.
If the boiler detects an overheating in the sanitary hot water tank the safety thermal limiter will operate. The boiler
will be switched off, including the heating.
Once the cause of the overheating has been eliminated, the thermal limiter of the S.H.W. must be re-armed.
To do so, unscrew the black cap and push the small pin behind it until you hear a click.
The limiter will not re-arm until the temperature in the S.H.W. header tank has gone down to below 80°C.
S.H.W. SAFETY VALVE
A safety valve set at 7 kg/cm
2
will activate if the pressure in the S.H.W. accumulator tank exceeds said value,
expelling water. It is essential that this valve runs to a drain.
S.H.W. RETENTION VALVE
This prevents the S.H.W. accumulator tank from emptying even when the water supply to the dwelling is cut off.
