Temperature sensors
The connection cable of the temperature sensor should be as short as possible,
it should not be route it in close proximity to the power cords and do not
twist around other cords.
The DHW cylinder temperature sensor can be optionally replaced thermostat, to
do this switch the input type Tcyl [CONFIGURATION> DHW TEMPERATURE>
REGULATION> OUTSIDE] and connect the NO contacts of the thermostat to the Tcyl
terminals.
Master appliance (entry MA)
In order to limit the power used, i.e. the boiler can cooperate with other
appliances such as an electric water heater. In order to do so, an electrician
should install in line an extra open contact to the MA entry (voltage free
entry), so that when a master appliance gets on, the contact opens, and the
boiler switches off- it results in heating blockage and pump’s standstill.
External adjustment of selected room temperature (inlet FN)
Closing FN contact shifts boiler’s work to the mode of maintaining the
temperature previously set in the configuration menu [CONFIGURATION> ENTRY
FN].
RT – room temperature regulator
Optional controlling the boiler operation depending on the room temperature.
RT entry should be activated [CONFIGURATION> ROOM TEMP.> TEMP. SENSOR> RT] –
then opening the voltage free contact will result in the switch off heating up
the CH.
Three-way valve control (TWV entry)
Switching the boiler operation to central heating or heating water in the coil
of DHW cylinder is carried out using a three-way dividing valve with an
actuator. Depending on the model used, the device should be connected as shown
on the diagrams, page no. 8 and the manual of valve and servomotor. Note: In
case of activation DHW cylinder you should follow Service / Configuration –

select command „delete” and press the dial. To add new time frame, select last
defined time frame and by pressing the dial go to command position, select
command „add” and press the dial to add new time frame (edition of new time
frames described above) .
If there are no defined time frames, then after selecting „new” the time frame 00:00am to 23:59pm will be set , which should be edited in accordance with user’s needs.
The daily program will be saved to the boiler’s settings by pressing the command „END”.
TURBO function
If the facility is cold and if it is necessary to heat it up quickly, there is
a possibility to turn on the TURBO function. This function, when conditions to
turn on the heating are fulfilled, starts central heating installation with
maximum parameters and continues until required temperature is reached in a
room. This function can start automatically when room’s temperature falls down
by the set room temperature hysteresis.
Automatic work is set in menu CONFIGURATION > AUT. TURBO MODE. Selection of
„Hot water tank- NO” will result in switching off hot water heating priority
for the time of using Turbo function. In menu PARTY/ HOLIDAY/ MANUAL it is
possible to turn on this function manually (without hot water heating up
priority), in condition that the room’s temperature is lower than the
programmed one. Sensor Tr is required to turn on Turbo function
Frost protection
Frost protection is activated automatically during stand- by and HOLIDAY mode
(power mode only on cylinder). It can be activated in the time frames for
installations of CH and DHW or during the HOLIDAY mode. The installation
protection will be activated if the outside temperature falls below 2°C or the
room temperature drops below 7°C. In this case, the CH circulation will be
activated.
The temperature will be set according to the heating curve estimations or
manually set according to the regulation. Tr sensor is required to activate
this function.
The function is disabled when the boiler is controlled by an external room
controller or other external sensor connected to the RT input. In this case,
the frost protection mode must be enabled on the external controller, the
boiler will maintain temperature set manually or based on heating curves.
Heating curve
Boiler’s controller is responsible for maintaining proper temperature in
central heating installation depending on the outside temperature. While the
temperature outside the facility is low, heat demand within the facility is
higher, whereas while the temperature outside is high, analogically, there’s
no need to maintain high temperature within the installation. Correlation
between outside temperature and heating installation’s temperature can be
presented in a graphical form of so called heating curve. The diagram below
presents a compilation of heating curves for the set point of room temperature
equal 22°C. Depending on the facility characteristics, climate zone, and the
type of heating installation one must select appropriate heating curve.
In case of the need to offset the heating curve, it is necessary to change the parameter [heating curve]. The diagram below presents heating curve no. 12 with the offset -10°C and 10°C.
