Exist properly functioning, and if temperature T1 at domestic water inlet is higher than domestic water exit
Temperature T2, then there is error running.Depending on there is properly functioning or error running, control dress
Put and can be run in different patterns in other words by different programs.
At this it is particularly preferred that store one of three below state in a memorizer:
0: need to check,
1: properly functioning,
2: error running,
Wherein, when Straight-through heater initializes and/or when longer downtime, memorizer is set to
Position is " 0 ", wherein, especially repeats the inspection to through-flow direction in error running.At delivery shape
In state, i.e. before the initialization first or first start of Straight-through heater, store in memory
Need to check.Therefore check when first start, see that hot water line and cold water pipeline are the most correct
Be connected.Add heat-heat exchanger for this and detect the temperature at domestic water inlet.When needed
Additionally detect the temperature in domestic water exit and compare with the temperature at domestic water inlet.Also
It is contemplated that detect whether to carry out liquid discharge by flow transducer.If domestic water inlet now
The temperature at place, higher than the temperature in domestic water exit, stores, Straight-through heater the most in memory
Error running works.If the temperature in domestic water exit is increased beyond at domestic water inlet
Temperature, then storage, Straight-through heater is in properly functioning middle work.In error running,
This user sets and is the most reliably limited, and wherein, such as can not realize during this operates in economic model,
Thus do not carry out the unnecessary cooling of heat exchanger.Specify in error running at this, carry out through-flow direction
The inspection updated periodically.
Preferably keep in error running at this temperature of heat exchanger temperature upper limit and lowest temperature it
Between.This can such as be carried out by Fuzzy tuning.
Preferably use ratio at properly functioning middle high rated value in error running.Thereby guarantee that, even if
The liquid of enough heat is also arranged by the incorrect connection of cold water pipeline and hot water line from heat exchanger
Go out to hot water line.Wrong identification is improved at the same time by the rated value improved, because rated value
Improve and cause the temperature of the increase when drain to improve.

And the actual temperature at domestic water inlet 21 is adjusted.Although thermal source 52 provides heat energy to arrive heat
Exchanger 2, but if the temperature at domestic water inlet 21 declines, then cold water pipeline 31 and heat
Water lines 32 is properly connected and realizes properly functioning, and wherein hot water exports 22 at domestic water
It is discharged, thus the temperature that domestic water exports at 22 is adjusted to rated temperature.
The Straight-through heater 1 heating when load running first is independently carried out with situations below at this,
I.e. which pattern of Straight-through heater 1 is set, i.e. for example whether have selected economic model, at warp
In Ji pattern, the heating of heat exchanger 2 is carried out the most when needed.
If being also carried out now domestic water outlet in addition to the temperature detection at domestic water inlet 21
Temperature detection on 22, then determine through-flow direction simply by the comparison of two temperature is comparable.
If domestic water exports the temperature at 22 and exceedes at domestic water inlet 21 during drain
Temperature, then Straight-through heater be positioned at properly functioning in.If the temperature at domestic water inlet 21
When exporting the temperature rising at 22 relative to domestic water on the contrary, then Straight-through heater 1 is positioned at mistake
In operation.Wrong identification can be at this additionally by arranging a flow transducer improvement.
If do not cooled down on domestic water inlet 21 when drain, the most not under occurrence temperature
Fall, then error running it may be provided that.
Allow the most additionally be added and also add in existing through type according to the method for the present invention
Hot device is reequiped.Only when cold water pipeline 31 and hot water line 32 connect improperly, the method is
Come into force.During here, i.e. box lunch does not carry out correct connection, i.e. when Straight-through heater 1 is in mistake
When operation works, it still is able to reliably export the liquid of heating.The identification of mistake can be very simultaneously
Realize simply, thus repair can carry out very fast and thus only result in few expense.
Unrelated with the pattern of regulation by checking at this of the through-flow direction of the heating of Straight-through heater 1
Whether ground is carried out, the most such as, run unrelated in economic model or comfort mode with Straight-through heater 1.
In error running, the temperature of heat exchanger 2 is maintained between lowest temperature and temperature upper limit, the hottest
Exchanger 2 remains in the temperature of raising.In properly functioning, at this such as in economic model
Setting in likely, it is allowed to the cooling to a great extent of heat exchanger 2, in order to save energy
Amount.
It is delivered to the heat energy liquid to be discharged in a conventional manner according to output quilt from heat exchanger 2
Control, according to present invention provide that, the temperature at detection domestic water inlet 21, thus i.e. box lunch cold water
When pipeline 31 and hot water line 32 miss change ground connect, it still is able to the temperature of the realization liquid to exporting
Regulation.
