Reduced with experience, to solve this problem it is necessary to be adjusted to current design temperature, so that water heater disclosure satisfy that use
The normal water demand at family.
In this step, the relation between outlet water temperature range is preset according to described minimum leaving water temperature and water heater, really
The positive temperature of periodical repair, can generally comprise following several situation：
1., when described minimum leaving water temperature is less than lower limit (as 38 DEG C) that outlet water temperature range preset by water heater, heat is described
The hot water deliverability of hydrophone can not meet user's request, now in order to meet user's request, needs to heighten water heater current
Design temperature, therefore can determine that described correction temperature is the first positive preset value in this case；
2., when described minimum leaving water temperature is more than the upper limit (as 45 DEG C) that outlet water temperature range preset by water heater, heat is described
The hot water deliverability of hydrophone, beyond user's request, now in order to save electric energy, should turn down the current design temperature of water heater,
Therefore can determine that described correction temperature is the second negative preset value in this case；
3. when described minimum leaving water temperature be more than or equal to water heater preset outlet water temperature range lower limit and less than or wait
When the upper limit of outlet water temperature range preset by water heater, illustrate that the hot water deliverability of now water heater disclosure satisfy that user's request
And do not constitute waste, thus may determine that described correction temperature is null value, do not need adjustment water heater current in this case
Design temperature.
Step 103：It is adjusted according to the described temperature design temperature current to water heater of revising, and by the temperature after adjustment
Degree as follow-up time heater inside design temperature to realize the control to water heater；Wherein, follow-up time refers to positioned at institute
State the time after preset time period.
In this step, it is adjusted according to the correction temperature of the step 102 determination design temperature current to water heater, and

Used, meet user's daily water consumption demand.
For example, water heater was started working November 1 and is automatically provided with 50 DEG C of a preliminary set time by water heater
(first setting can also be for manually setting), it is assumed that water heater presets outlet water temperature range as 38 DEG C～45 DEG C, is passed by temperature
The minimum leaving water temperature that sensor obtains one day on the 1st heater inside of November is 34 DEG C, then according to this minimum leaving water temperature and hot water
The relation that outlet water temperature range preset by device understands, the current hot water deliverability of water heater can not meet user's request, in order that
Water heater disclosure satisfy that user's request, need 50 DEG C of the design temperature current to water heater to be adjusted, to set described in improving
Constant temperature degree, and using adjustment after temperature (as 52 DEG C) as November water heater on the 2nd design temperature to realize the control to water heater
System.Certainly, if the minimum leaving water temperature of the water heater obtaining November 2 is still below described water heater and presets outlet water temperature range
38 DEG C of lower limit when, need again 52 DEG C current of design temperature to be adjusted, to meet user's water demand, and will adjust
Temperature (as 54 DEG C) afterwards as November water heater on the 3rd design temperature to realize the control to water heater.It is understood that
If the minimum leaving water temperature of the water heater obtaining November 2 is higher than 45 DEG C of the upper limit that outlet water temperature range preset by described water heater
When, illustrate that the current hot water deliverability of water heater, beyond user's request, in order to save electric energy, should turn down water heater current
Design temperature, and using adjustment after temperature (as 51 DEG C) as November water heater on the 3rd design temperature to realize to water heater
