WARNING!: If working pressure continues to

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), and pump continues to work until room
thermometer turns off. Heaters will again turn on when water
temperature fails 2°C below set temperature – if room
thermostat requires so. 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.
If relay of pump does not turn on for any reason,
heaters will not too.
-
When room temperature is reached, microprocessor turns off
heaters and pump, but after 2 min after heaters turn off – during
that time LED diode indicating work of pump will flash meaning
that countdown 2 minutes is in progress after which time the
pump will turn off.

7.3.3 Warnings about pressure
If the pressure in the system decreases to
bar, the boiler works normally, but diode indicating
pressure measurements starts to flash slowly (Figure 18).
It is necessary to re-fill installations up to P≤0.7 bar in
order to a stop automatic flashing.
If pressure increases up to P≤2.2 bar, boiler work
normally but pressure measurements indicator starts to
flash slowly (Figure 18). It is necessary to reduce the
pressure to P≤2.1 bar in order to stop automatic flashing.
P≤0.6
Pressure measurements are done by digital sensor
integrated in circular pump. If the sensor is stopped or in
circuit break, then all heaters and pump will turn off
(delayed for 2 min), and pressure measurements indicator
starts to flash quickly. Display still has present temperature

is necessary to increase temperature to T≤5°C in order to
stop automatic flashing of warning indicator.
T≤4°C,
Present temperature displayed on the screen is possible
for values T≤-9°C. Temperature below -9°C is not possible
to be displayed on the screen so the code EL will appear
on display meaning the temperature is below -9°C, or
temperature sensor is in circuit break (Figure 23).
