MIN. SETPOINT
TEMPERATURE IN
HEATING MODE
Setting of minimal allowed setpoint
temperature in heating mode. Setpoint
temperature cannot be adjusted lower
as with this parameter.
5 ÷ 70 °C

MAX. SETPOINT
TEMPERATURE IN
HEATING MODE
Setting of maximal allowed setpoint
temperature in heating mode. Setpoint
temperature cannot be adjusted higher
as with this parameter.

MIXING VALVE
I - CONSTANT
Setting of mixing valve control fre-
quency - how often mixing valve posi-
tion is being controlled. Smaller value
means low frequency, higher value
means higher frequency.
0,4 ÷ 2,5
1
MIXING VALVE
P - CONSTANT
Setting of mixing valve position
correction intensity.
Smaller value means shorter
movements, higher value means
longer movements.
0,5 ÷ 2,0
1
BACKLASH OF
MIXING VALVE
Setting of mixing valve running time to
compensate the backlash of actuator
and mixing valve assembly, which
occours by change of rotation
direction.
0 ÷ 5 Sek
1
MIXING VALVE
D - CONSTANT
Sensitivity of mixing valve for stand-pipe
temperature changes. Smaller value
means low sensitivity, higher value
means high sensitivity.
0,4 ÷ 2,5

BOILER CIRCULATION
PUMP - TIME OF BOILER
TEMPERATURE
INCREASE (SECONDS)
This function is used in regulation of re-
turn in solid fuel boiler. In the set time,
the regulator determines temperature
increase of the boiler by 2°C. If an in-
crease in the boiler is determined, the
regulator activates the circular pump.

BOILER CIRCULATION
PUMP
OPERATION
1. STANDARD
2. PERMANENT
The setting informs us about the opera-
tion of the circular pump of the boiler:
1-STANDARD menas that the pump is
operating according to the minimum
set temperature of the system, and
when the difference between the boiler
and return line.
2-PERMANENT means that the pump is
operating continuously when boiler
temperature is higher than
the set minimum set temperature of
the boiler. This mode is used for pellet
boilers when there is no sensor
available in the thermal storage.
