1. Lower temperature can be automatically reduced when the calculated value is too high. In this case, the
regulator will accept a value (
maximum temperature - 5°C
) as the lower temperature.
2. If the automatic upper temperature is turned on, the lower temperature principle is set as follows:
Tlower_automatic = Tupper_aut (Tlower - Tupper)
Operation modes
The buffer can be loaded only based on buffer sensors temperature, so-called continuous loading. Moreover, it
is possible to specify one time period in which buffer loading is possible. The buffer loading process will not be
triggered outside this period.
Continuous loading
Activation of this parameter results in cyclic buffer loading based on buffer sensors temperatures and lower and
upper temperature settings of the buffer.
Temporary loading
For this mode, the user must also set the time of two parameters, i.e. the beginning and the end of buffer
service. Between these hours, the buffer will be loaded the same way as it is loaded in the "continuous loading".
Buffer loading outside the set hours is blocked.
The beginning of service
Set the hour to begin the buffer loading service (see
Operation modes
).
The end of service
Set the hour to end the buffer loading service (see
Operation modes
).
Minimum temperature of pumps
In a situation when the upper buffer sensor measures a temperature that is lower than the set temperature, the
CH pump will be blocked. This eliminates needless consumption of electric energy if the buffer is discharged.
Automatic upper temperature
When this option is activated, the regulator will automatically determine the
upper temperature
parameter.
The device will be set to the desired temperature for the CH circuit. It will also determine a new boiler operation
temperature - it will amount to (
maximum temperature -2°C
). Thus, setting the value (
Upper temperature
) is
ignored. If the
automatic
.... option is disabled - the regulator will operate according to the
Upper temperature
parameter setting.
Default settings
After choosing the DEFAULT SETTINGS option, the regulator goes back to factory parameters. The scope of
settings displayed using this command depends on granted authorization.
If the user selects an option,
user settings will be displayed to the defaults only.
When the Installer selects the factory settings after entering the SERVICE option (after providing the installer
password), the regulator will show a greater extent of settings. The parameters from the user menu and the
service menu will be brought back e
xcept for submenu parameters: SERVICE-> BOILER.
