switched off. When operating in combined mode, the three-way valve is automatically switched to heat the heating
system.
WARNING!
The maximum value of water temperature in the boiler of indirect heating +60°C
(limited to the service menu).
6.3.24 For optimal heating of water in the DHW circuit it is necessary that the temperature of the coolant at the boiler
outlet was 20 - 25°C above the set value of water temperature in the boiler (see section "Service menu" Table 3
Parameters ., ., .).
6.3.25 When activating the "Anti-Legionella" function (indicator____), the boiler heats the water in the boiler of
indirect DHW heating to a temperature of + 70 ° C and maintains it for 10 minutes. After that, the boiler returns to
operating mode. The indicator____goes out when the "Anti-Legionella" function expires.
WARNING!
The "Anti-Legionella" function is available after switching on the boiler regardless of the
selected operating mode. When activating the "Anti-Legionella" function, the value of the
operating settings of the boiler in DHW mode.

6.2.5 When the boiler is in standby mode (power supply is supplied, external circuit breaker is switched on), all protective
functions of the boiler are active, including the "Antifreeze" function. The indicator button on the display lights up in
red____.
WARNING!
"Antifreeze", are not active. Therefore, it is important to consider the ambient temperature.
coolant from the boiler, heating system and hot water supply circuit.
6.3 SELECTING AND SETTING THE OPERATING MODE
6.3.1 After switching on from the control panel, the following boiler operating modes are available:
►heating mode;
►DHW mode;
►combined mode (boiler works for DHW and HS heating).
WARNING!
Water heating in the DHW indirect heating boiler is a priority mode of boiler operation. When
heating the water in the DHW boiler, the heating system does not heat up!
6.3.2 The algorithm of the "Antifreeze" function is implemented as follows. The boiler controls the temperature of the
coolant at the boiler outlet. When the temperature drops to +5°C, the circulation pump starts automatically, the
three-way valve is moved to the "Heating system" position, and the heating of the heating system is switched on. The
message "AFr" appears on the display. Heating continues until the temperature of the coolant at the outlet of the boiler
+ 30°C. After that, the heating is switched off and the message "AFr" disappears on the display.
WARNING!
When the "Antifreeze" function is activated, the DHW circuit heating stops automatically. At
the end of the "Antifreeze" cycle, the boiler returns to its original mode.
6.3.3 The "Pump and three-way valve protection" function is activated if the pump and three-way valve have not been
operated for 24 hours. The pump will switch on for 1 minute and the three-way valve will switch and return to its original
position. When the function is activated, the message "PPr" (Pump Protection) appears on the display.
In case of prolonged disconnection of the boiler from the mains, it is recommended to periodically start the boiler at
least once a month at regular intervals.
6.3.4 Operation of the circulation pump in any operating mode of the boiler is indicated____by an indicator on the control
panel.
6.3.5 Implementation of the "Child lock" function involves locking the control panel. The control panel buttons are
automatically locked when switched off for 20 seconds or when the button is pressed briefly (1 second)____.
6.3.6 Control of operating modes and parameter settings are available from the control panel, the appearance of which
is presented in Figure 3, as well as through the appendix (the operation of the program is described in Appendix 1 to this
manual).
6.3.7 To unlock the control panel, press and hold the button for 5 second____.

► room air temperature (temperature sensor supplied with the boiler) is indicated by an indicator____;
► the value of the difference between the on and off temperatures of the boiler;
► Input value (contact status) "Thermostat".
6.3.10 With the active parameter "Coolant outlet temperature" (indicator____), the boiler maintains the coolant outlet
temperature set for the heating mode. Automatic switching on of the boiler heating elements occurs when the coolant
temperature decreases (by default - by 5 ° С from the set temperature parameter____). When the heating is switched on,
the indicator____lights up on the display. The heating will be switched off when the coolant temperature reaches the
set value.
