parameters), the following warning message will
appear on the display:
To restore the boiler to operation, switch off the
alarm by pressing the encoder and restarting the fire-
up procedure.
9.5. Manual Mode
In this mode each individual actuator is enabled and
disabled independently of the other. In addition to the
Manual Mode function, the Blow Force function has
been provided. Blow force is appear in percentages.
This function allows you to set the blow force of
the fan while in the Manual Mode. Pressing the
ENCODER activates the fan. The fan will operate until
the ENCODER is pressed again.
Press the ENCODER to enable / disable the central
heating pump.
Press the ENCODER to enable / disable the (water
heater) hot consumption water pump.
Press the ENCODER to enable / disable the alarm.
9.6. Central Heating Pump Activation
With this function, you can set the temperature
that will activate the central heating pump (the
temperature is measured on the boiler). The pump
will start if the setpoint temperature is exceeded.
The pump will be deactivated when the boiler
temperature drops below the activation temperature
(minus hysteresis, e.g. 2°C). In this case, the pump
will stop at boiler temperature of 33°C.
9.7. H.C.W. Pump Activation
With this function, you can set the temperature
that will activate the hot consumption water pump
(the temperature is measured on the boiler). Above
the setpoint temperature (e.g.
40°C
), the pump is
activated and operates depending on the selected
operation mode. The pump will be deactivated when
the boiler temperature drops below the activation
temperature (minus hysteresis, e.g.
3°C
). In this case,
the pump will stop at boiler temperature of
37°C
.
9.8. Operation mode - by selecting one of four
operation modes
9.8.1. House Heating Priority
If you select this option, the controller will switch to
the house heating mode. The central heating pump
starts to run above the pump activation temperature
(set to
35°C
by default). Below this temperature
(minus central heating hysteresis), the pump is shut
off. While in the house heating mode, the letter D
is displayed in the bottom right corner of the main
screen.
9.8.2. H.C.W.Priority
Activating the hot consumption water priority will
cause the regulator to switch into the water heater
priority mode. In this mode, the (hot consumption
water) heater pump is activated until the set H.C.W.
temperature is reached.
Then, the
H.C.W. pump
is shut off and the
C.H. pump
is activated. The central heating pump will run
until the water heater temperature drops below the
setpoint value (and the
H.C.W. hysteresis
); then,
the C.H. pump is shut off and the
H.C.W. pump
is
activated. In this mode, the fan is operated as long
as the temperature is below
62°C
to prevent the
boiler from overheating. The hot consumption water
priority function consists in that the consumption
water is heated up before heating up water in
radiators. While in the H.C.W. Priority mode, the
letter B is displayed in the bottom right corner of
the main screen.
*
ATTENTION: The boiler should have
non-return valves mounted on the
central heating pump circuit and the hot
consumption water pump circuit. A valve
mounted on the hot consumption water
pump will prevent hot consumption water
from being drawn from the water heater.
9.8.3. Parallel Pumps
In this mode, the pumps start to run in parallel above
