A - this menu is used to set the parameters that have numerical values (°C, RPM, time...)
example: adjust the burner fan rpm, adjusting the boiler temp. etc...
B - this menu is used to set parameters that must be selected (marked) to be enabled and there can be multiple selected
(enabled) items
NOTE: some enabled options disable another one (they can't be enabled at the same time)
example: enable additional equipment: flap, air cleaning, CM2K, Cm-WiFi-box...
C - this menu is used to set the parameters that must be selected but there can be only one selected item
example: set the type of the DHW sensor

BURNER STOP PROCEDURE / CONTROLLER STOP PROCEDURE
Correct ways to stop (turn off) the burner (get to the OFF phase):
- manual burner stop (turn off) by pressing ON/OFF button if burner is in any phase except the OFF phase (no matter if
external control is enabled or disabled)
- burner stop (turn off) by schedule (if enabled) (no matter if external control is enabled or disabled)
- burner stop (turn off) by WiFi or CM GSM (additional equipment) (no matter if external control is enabled or disabled)
Correct controller stop (turn off) procedure (main switch 0/1)
- first thing to do is to get the burner into the OFF phase – the burner is turned off (unless it is already in that phase)
- switch off the main switch 0/1 (put it into the 0 position)
- the main switch (0/1) on the controller is not intended for
switching the controller on and off
- the burner must be in the OFF phase before switching the
controller off on the main switch

BURNER START PROCEDURE (START IS ENABLED)
The ways to activate ''start is enabled'' of the burner (burner goes from the OFF phase to the A0 phase (burner
starts) or to the S7-3 waiting phase (STANDBY)):
- manual activation by pressing the ON/OFF button
- activation by schedule (if enabled)
- activation by WiFi or CM GSM module (additional equipment) (if it is enabled in drop-down menu and in "Work
mode"/"Additional equipment"/"Internet supervision")
burner in the waiting phase s7-3 (standby) – causes:
- set boiler temperature is reached (controller waits the boiler temperature to drop below set difference)
- there is no heating demand (from heating circuits and/or DHW tank) (controller is set to start according to the heating
demands
- external control, that is enabled, turned the boiler off
Notes:
Burner may get into the S7-3 waiting phase right after start is activated (from the OFF phase) because one or more of
the S7-3 waiting phase causes are fulfilled.

5.1. FORCED SHUTDOWN
This option is used to forced shut down of the burner in any working
stage. Before pressing the "FORCED SHUTDOWN" you must switch
off the burner on the ’’ON/OFF’’ switch and confimt ’’STOP’’ action on
the main display.
NOTE: after "FORCED SHUTDOWN" you must open the boiler
door with burner, and clean the burner grate before starting the
burner again.
This menu is used to check the relay outputs, the connection to the electrical parts and the operation of the electrical
parts of the boiler. Pressing the Start button starts the selected component, pressing the Stop component button stops
functioning.
Parts:
- burner fan: you can check the operation of the burner fan in 2 speed (maximum RPM and 1700 rpm) - when you turn
on the test, the measured RPM is displayed on the screen. If max. RPM printed more than 3000, measurer RPM is not
well positioned or is defective
- pellet transporter: the operation of the pellet transporter can be checked
- el. Heater + burner fan: the burner heater function (igniter) can be checked - to protect the burner el . heater, the
burner fan is automatically switched on when the heater is switched on
- pump P1 / DHW / RECIRCULATION: the operation of all connected pumps can be checked
- 1.circuit / 2. circuit: it is possible to check the operation of all mixing heating circuit elements (pumps, opening / closing
of actuator)
- mixing valve (with actuator (backflow protection))- it is possible to check the operation of the mixing valve actuator
(backflow protection)
- when in the manual test ( mixing valve ) is pushed button “START“ (close MV!)" valve must close the water flow
from the heating installation into boiler and open the bypass (case1 and case 3 or mirror image if the mixing valve is
installed on the left side of the boiler).
- when in the manual test ( mixing valve ) is pushed button “ START “ (open MV!)" valve must open the water flow
from the heating installation into boiler and close the bypass (case2 and case 4 or mirror image if the mixing valve is
installed on the left side of the boiler).
- additional equipment: menu for manual test of the installed additional equipment

5.3. PELLET TRANSPORTER
Filling feeder screw:
This option is used to initially filling of the transporter. It can also be used if the transporter is emptyed. We recommend
that you start the procedure and wait for the process to complete to make sure the transporter is full (20 min.).
Before starting this option, disconnect the plastic flexible tube from the burner and place the bucket / bag underneath.
After finishing the process, empty the pellet / bucket bag into the pellet tank and connect the plastic flexible tube back to
the burner.
Filling at start check:
This option is used to control the initially filling of the burner. By pressing the "START" key the transporter will start
working and continue continuously until the set time has elapsed (the counter starts to count down). The specified time is
set in the Initial Charge parameter in the "INSTALLATION" menu. After the transporter has stopped working it is
necessary to open the burner door and check if the pellets are covered. El. heater for correct ignition (open the lower
door and close them after checking (microswitch)) - follow the instructions on the screen. After completion of the control
and eventual correction of the initial charge time (+ 10%), the control automatically records the done change, the boiler
starts automatically without initial charge! (so you do not need to clean the pellet grate manually). If you do not want to
start automatically after the control, the "5. Operation mode-> 5.1.Forced Shutdown" may turn off the burner, but after
that you must clean the burner grate.
Possible Reasons for Correction:
If the pellets are not covered the el. heater, the pellet transporter may be either insufficiently filled or the initial filling time
should be extended (in steps of 10 seconds).
This option is used to check pellet delivery amount.
You can set the transporter working time (1) after which you want to weight the pellet.
On screen is displayed factory amount and last measuring which can be done only by authorized serviceman (if has
been done, if not factory and last weighning is the same).
In order to weigh more precisely weighing must be repeated at least 3 times.
NOTE:
If the transporter is empty, it must be filled before the burner is started.
