Abnormality detection condition
Hot water supply temperature (TH5)
above 60qC for 30sec, at condition
where water fully open is detected.
Step 1 (normal): During hot water
supply, hot water supply, hot water
supply temp (TH5) is hot water
setting temp. +10k. When above
mentioned condition continues for
30sec., shift to Step 2.
Step 2 (normal): Control to fully close
at flow adjust valve. When it is at full
close position, shift to Step 3. During
full close control, check hot water
supply temp. (TH5), if hot water
supply temp. is below setting temp.
+10k, shift to Step 1.
Step 3 (normal): When condition of
hot water supply temp. (TH5) is
above setting temp. +10k has
continued for 30sec., check hot water
supply temp. abnormality (H87).
Step 1 (normal): When operate to
water side with Maximum speed
(250pps), do the "valve fully open to
water side sequence" for 45sec. and
if cannot detect water full open
position, shift to step 2.
Step 2: Stop PUMP 1
Step 3: Do the "valve fully open to
water side sequence" for 45sec. and
if still cannot detect water full open
position, shift to step 2.
