5.6.4
SUMMER MODE
In this mode, only DHW pump is active (enabled when the DHW pump activation threshold is reached) and the CH valves are
closed in order not to heat the house unnecessarily. If the CH boiler temperature is too high, the valve will open in an emergency
procedure.

EEKLY CONTROL
This function enables the user to program daily changes of the pre-set CH boiler temperature (CH boiler weekly control
submenu) for particular time and day of the week.
NOTE
To ensure that this function works properly, it is necessary to set current time and date.
In order to activate the weekly control function, select Mode 1 or Mode 2. Advanced settings of these modes are available
further in the submenu: Set mode 1 and Set mode 2.
Once a given mode has been selected, the main screen displays the value of current temperature deviation (below the pre-set
CH temperature, alternately with Pre-set). It also indicates that the weekly control function is active.
How to change weekly control settings:
The EU-800 PID regulator offers two ways of configuring weekly control:
MODE 1 – the user sets the temperature deviations for each day of the week separately;
MODE 2 – the user sets the temperature deviations for all working days (Monday-Friday) and for the weekend (Saturday-
Sunday) separately.
How to configure mode 1:
To program mode 1, select Set mode 1 - the display shows a screen with individual days of the week.
After selecting the day of the week to be edited, the editing screen appears: the current deviation setting is displayed in the
upper line, and the time period in the lower line. Turn the pulser knob to move to the next time period. To edit the setting, pre
the pulser knob and select Change.
In order to copy the settings to the following hours, use the pulser knob and select Copy.
