Operation manual

14

Automatic set point operation

This operation mode contains a learning function to predict
the daily hot water consumption. It will calculate and predict
the optimum tank temperature setpoint based on the user
tapping history.
Enabling this operation mode will keep the tank temperature
as low as possible but to a temperature which guarantees a
high comfort level.

The advantage of a low tank temperature setpoint are :

-

Reduced heatlosses

-

Better unit performance, the lower the tank temperature the 
better the heat up coefficient of performance (COP). 

-

Lower electric power consumption

calculation

[1-00] Renewal time for set point calculation

The automatic temperature set point calculation is done on a
daily basis. The algorithm calculates for each day of the week an
optimum domestic hot water tank temperature set point. To
calculate this temperature setpoint, the learning function
monitors per 24 hours the domestic water heating demand and
based on this demand calculates the optimum set point for that
specific day of the week.

This field setting contains the starting time for the 24 hours
monitoring period.

This field setting must be set preferably after the main heating
up of the domestic water of the day has finished.
For example: If in schedule timer operation mode the schedule
timer was set from 22 h until 6 h, the renewal time should be set
at 6 h.

[1-01] Minimum automatic temperature set point

If required the minimum temperature set point for the automatic
set point calculation can be adjusted. If, for example,
considerable heatlosses are expected on the field piping
between the hot water tap and the domestic hot water heat
pump, this temperature set point can be usefull.

[1-02] Maximum automatic temperature set point

The maximum temperature that the automatic set point can
reach.

However, if this value is set on a temperature higher than 60°C,
that maximum temperature will only be reached when field
setting [3-02] is set to 1 (ON). If the setting of [3-02] is 0, the
maximum temperature will be 60°C (only heating up by heat
pump) ignoring higher set temperatures.
