7.3 Regulation of heating

Circulating pump and electrical heaters turn on by
command of room thermostat

When boiler reaches set temperature of water in the
system, heaters turn off (with intervals of 3 sec to eliminate
shock to electric power net). When the current water
temperature drops 2 ° C below the set - the heaters are
switched on again, but not all, but 1/3 of the set power. The
controller monitors the dynamic temperature rise and based
on that determines the minimum engaged power of the
heater, which is sufficient to maintain the set temperature
of the boiler, ie minimizes electricity consumption. Energy
Microprocessor thermo-regulator measures time of work for
each heater, changes heaters (if there is inactive heater
available) after 30 min of continual work. Such working
mode provides equal load of all heaters and relays, and
their life-time is significantly longer

When room temperature is reached, microprocessor turns
off heaters.
7.3.1 Boiler set temperature adjusting
Using buttons
‘‘▼’’
or
▲
select mod to display set temperature
- LED diode near the sign
„
Set temp
“
is on. Press button
’’ P“
,
LED diode near to the
sign „
Set Temp
“
starts to flash, which
means it is possible to increase/decrease given temperature of
the boiler using button
‘‘▼’’
or
▲
(image 16). Each touch to the
button will increase/decrease given temperature of the boiler
for 1 °C. Working temperature range is 10 °C ÷ 80 °C
.
Confirmation of change must be done by pressing button
’’P“
.
If change is not confirmed, 15 sec after pressing any button
(except
’’ P“
), controller continues to work on old value of set
temperature and exits adjusting mode.
When change is confirmed pressing button
’’
P
’’
, display keeps
the new value of temperature for 15 sec, and then returns back
to basic representation, or the present temperature will appear
on display
.
7.3.2 Boiler given power adjusting
Use the
‘‘▼’’
or
▲
buttons to select the mode for setting the
default power - the LED next to the " Sets power " indicator
lights up. Now press the
“P”
button - the LED blinks next to
" Set Power ", which means that it is possible to increase or
decrease the default power boiler using the
‘‘▼’’
or
▲
buttons.
Each keystroke increases or decreases the default power
boiler 1 step power (see Table 6).
In order for the change to be accepted it must be confirmed by
pressing the
“P”
key. If the change is not confirmed, within 15
sec. by pressing any key (except for
“P”
), the control resumes
operation according to the old default power value and exits
from the setting mode.
When the default power change is confirmed by pressing the
“P”
key, the display will display a new setpoint of 15 sec and
then return to the basic display, the display will show the
current temperature.
