RT10 room thermostat, connected to the RS output inside the external socket in the front of the
boiler.
4.4 Ignition function
If this function is activated, the boiler responds to the instruction from the room thermostat by
switching off/on immediately.
If this function is deactivated, the boiler responds to the no-heat instruction from the room
thermostat by lowering the set CH temperature by the value set in the Reduce Temperature by
Thermostat function. This solution is advantageous for heating systems with a large volume of water
in the system, where complete deactivation of the boiler would mean a large drop in system
temperature and a long reheating.
4.5 CH pump - room
thermostat
CH pump is started and deactivated together with the boiler on the basis of an instruction from the
room thermostat. If the boiler switches off, the CH pump is switched off and vice versa.
4.6 Temperature reduction
by thermostat
The boiler responds to a shutdown instruction from the room thermostat by lowering the CH
temperature by the set limit. In case the item Ignition function is deactivated, then in this item you
set by how many °C the set CH temperature should be decreased so that the boiler operates at a
lower temperature and thus saves fuel by automatically modulating the power downwards.

Connect the thermostat standard 1, 2 to the output "Room reg 1,2 and Com" in the control unit.

Connect the OPOP controller (type RT10) to one of the RS data outputs in the control unit.
5. Lambda *
Regulates the residual oxygen in the boiler using a lambda probe.
5.1 First time for update
Delay of the first regulation intervention. During this time, the lambda sensor is waiting
for preheating. After the automatic ignition, it is necessary to wait around 5 minutes for
the flame to stabilise, then the lambda probe starts to adjust the combustion process.
5min.
5.2 Update period
Correction period, how often the regulation intervention and O
2
adjustment occurs in the
boiler.
The recommended time is 3-5min. The larger the burner, the longer the time must be.
3-5min.
5.3 Oxygen surge
Correction factor for pellet dosing in %. How big is 1 regulation intervention to the pellet
feed. The regulation will be according to the set time in the Update Period function.
2%
5.4 Fan surge
Correction factor for fan speed in %. How big is 1 regulation intervention for fan speed.
The regulation will be according to the set time in the Update Period function.
2%
5.5 Sum
Should the correction factor (oxygen surge, fan surge) be summed at each Update Period
until the specified O
2
is reached?
Yes
5.6 Min. change
Set the lower level of the correction range. The unit will not go lower than this limit when
trying to achieve the desired O
2
. If the Sum function is activated. If the Lambda probe
interferes with the operation of the external feeder and fan to such an extent that it
reduces the boiler maximum power, then the value set in this function is too high. It
should be set closer to 0% so that the Lambda probe cannot interfere so much with the
boiler power.
The Lambda probe is only to correct the flame not to maintain the unburned oxygen set
point in the boiler by forcing the boiler power down or up.
-10%
5.7 Max. change
Set the upper level of the correction range. The unit will not go higher than this limit
when trying to achieve the desired O
2
. If the Sum function is activated.
If the Lambda probe interferes with the operation of the external feeder and fan to such
an extent that it reduces the boiler maximum power, then the value set in this function is
too high. It should be set closer to 0% so that the Lambda probe cannot interfere so
much with the boiler power. The Lambda probe is only to correct the flame not to
maintain the unburned oxygen set point in the boiler by forcing the boiler power down
or up.

in % for maximum boiler power. Keep in mind that the lambda probe itself
has a certain measurement tolerance which is + - 1%. The boiler control unit is therefore
able to maintain the required oxygen in the boiler within 1 - 1% of the set value. We are
also talking about the average value of oxygen maintained in the boiler throughout its
operation. Short-term deviations of oxygen from the set value are perfectly normal due
to external factors such as changes in chimney draft, cleaning the burner by increasing
the fan speed (Burner Cleaning function in the Main Settings), etc.
