OPERATION MODES
The selection menu is displayed by pressing 1 button. The ▲ or ▼ buttons select the required
mode, and 4 or 1 buttons confirm the selection. Five seconds after a button is last pressed, the mode
selection menu is exited without changing the current mode. If no timer is activated, "Timers" mode
is missing from the menu list. If the clock is not set, the water heater only can switch on in "Heating”
mode. "Timers", "Smart Control" and "Self-learning" modes are inaccessible.
„Standby“ mode
This mode turns off all active operations of the water heater. Only the "Frost protection" function and
the option to enable "Delayed Start" are retained.
„Heating“ mode
The thermoregulator will maintain the user-set temperature. The heating element will switch on
when the temperature measured by the thermal sensor drops by 4 degrees below the set
temperature and will switch off when the set temperature is reached.
"Self-learning" mode
The purpose of this mode is for the thermoregulator to record, for a period of one week, when warm
water was used, so that "Smart Control" mode be able after that to make maximum electricity
savings while simultaneously provides sufficient quantity of warm water when necessary. After
completion of the full week cycle of self-learning, the thermoregulator will automatically switch to
"Smart Control" mode with "Schedule of use" priority.
Mode „Smart Control“
The "Smart Control" mode is intended for automatic selection of the most appropriate temperature
to which water will be heated, in order to achieve the lowest electricity cost under permanent provision of warm water. This
mode has three methods of operation from which the user chooses the one that best meets their needs.
The first method is with the "Low Cost Tariff" priority. This
mode will take advantage of the significantly lower
electricity price of a second tariff if available. When
selecting the most economical strategy for heating
during the current day, the thermoregulator will also
comply with the water consumption history for the last 7
days. "Eco" indicator shows if a more economical
heating algorithm operates currently, when values are to the left of the center, or more
uneconomical when values are to the right of the center. If for two or more consecutive days the
electricity consumption is low enough, the appliance will start operating in the most economical
control algorithm at "reduced power".
While the water heater is switched on in “Smart Control” mode, there is an option for forced water
heating up to the maximum temperature. This is made by pressing and holding ▲button for longer
than 2 sec. The screen displays the word "Powerful".
The second method is with the "Schedule of use" priority. In this mode, the thermoregulator
complies with the weekly warm water consumption schedule, saved by "Self-learning" mode.
The third method is with "ЕN 814" priority. This mode operates as the mode with “Schedule of use"
priority and has additional heating at certain time intervals in accordance with Directive 814/2013.
The warm water consumption graph for the current day features the current time in purple color and
the other times are in blue color.
ATTENTION!
џ
Set the system clock in order to activate the “Smart Control” mode!
џ
When the "Low Cost Tariff” priority is selected, it is important to properly enter the start and end time of that tariff!
џ
In order to operate "Smart Control" mode with "Schedule of use" or "EN 814" priority, it is necessary to have a
consumption schedule for a complete full week cycle of self-learning.
