10. REGULATOR WORKING DESCRIPTION
Regulator's work is based on suitable controlling of the fan and heating system
circulating pump to achieve assigned boiler and room temperature. After regulator
switching on or after switching off the boiler overheating indicator, the regulator
begins boiler burning; it is shown by green indicator.
The burning process is finished if boiler temperature achieves assigned value and
green indicator will switch off.
If boiler temperature does not achieve 65ºC during 2 hours of boiler working, the
regulator will switch on the fan and shows fuel shortage indicator.
During its work regulator shows an actual boiler temperature and controls fan
speed as below:
Ø If during of the burning process boiler temperature is lower than 60ºC
the fan works in 40 - 100% ; if temperature is higher than 60ºC the fan
works in 100% of its power
Ø If boiler temperature during its normal work is lower than assigned value more
than 10ºC then fan works in 100% of its power
Ø If boiler temperature during its normal work is lower than assigned value less
than 10ºC then regulator reduce the fan speed but not less than 40% of its
power
Ø If boiler temperature is higher or equal of assigned thermostat tempe-rature the
fan switches off
Ø The fan will switch on again when boiler temperature gets down about 5ºC of
assigned value
Ø To avoid gasses accumulation during boiler outage, the regulator makes 5-
secunds blows through the boiler every 1÷9 minute. The blows can be set-up
after regulator switching on when you can see (P1….P9, P-) on the regulator
screen; pressing (P-) you will switch off the blows.
If circulating pump works:
Ø during boiler burning , until boiler achieves 65ºC, pump is switched off
Ø if, boiler temperature is higher than 65ºC pump starts to work and works until
boiler temperature gets down to 60ºC to avoid excessive boiler pre-cooling
Ø if, during boiler operation the temperature temporarily gets down to 60ºC the
pump starts to work again after temperature achieves 65ºC
FUEL SHORTAGE
If boiler temperature gets down under 65ºC and it is continued by 30 min., then
regulator switch off the fan and switch on the fuel shortage indicator.
In case of regulation repeated switching off, you should:
Ø fill up the boiler with wood or to burn the boiler again if necessary
Ø turn the thermostat handweel to the left as much as possible
Ø wait until the fuel shortage indicator starts to blink
Ø set-up boiler temperature using of thermostat handwheel
BOILER OVERHEATING
If boiler temperature achieves over 85ºC, the regulator switches off the fan and
switch on the boiler overheating indicator. Then you should:
Ø wait until boiler temperature gets down
Ø remove boiler overheating reason (e.g. water shortage )
Ø wait until the overheating boiler indicator begins to blink
Ø set-up of boiler assigned temperature turning the thermostat handweel to the
right
Warning! Filling up with water should be done if boiler temperature gets
under 40ºC
Warning! If boiler temperature gets under 60ºC before cancelling of boiler
overheating - regulator begins boiler burning
Warning! Regulator is equipped with additional internal protecting thermostat
avoiding the boiler high temperature excess. When water temperature
in the boiler increase10ºC more than assigned one - regulator
automatically disconnect the fan then disconnecting of protection
follows after temperature gets down lower than assigned value.
