Attention:
in the proces of experimental
adjustement of proper heating curve it is
necessary to exlude influence of room
thermostat on controller work (irrespectively
if room thermostat is connected or not), by
adjusting parameter:
For mixer cycle:

Guidelines for correct heating curve settings:
Floor heating 0,2 – 0,6
Radiator heating 1,0 – 1,6
Buffer 1,8 - 4
Pic. 8 Heating curves.
Tips for choosing proper heating curve:
If by falling outer temperature room
temperature is increasing, then value of
chosen heating curve is too big,
If by decreasing outer temperature,
room temperature is also decreasing, then
value of chosen heating curve is too low,
If
by
frosty
weather
room
temperature is appropriate and in warmer
time is too low – it is recommended to
increase parameter
heating curve parallel
shift
and then choose lower heating curve.
If
by
frosty
weather
room
temperature is too low and in warmer time
too high – it is recommended to reduce
parameter heating curve parallel shift
and
choose higher heating curve.
Buildings which are poorly isolated require
setting heating curve with higher values, and
for better isolated buildings heating curve
will have lower value.
Preset temperature, counted according to
heating curve can be decreased or increased
by controller when it goes beyond scope of
limits of temperatures for given cycle.

NIGHT DECREASE SETTINGS
DESCRIPTION
In the controller it is possible to set time
periods of silo temperature reduction,
heating cycles, hot water silo, and circular
pump.
Time periods allow setting temperature
reduction in given time period – i.e. at night
or when user leaves the heated room.
Thanks to it preset temperature can be
reduced automatically, without loss of
heating
comfort
by
reducing
fuel
consumption.
To activate time periods use parameter
Night
reduction
for given cycle and activate it.
Night reductions can be defined separately in
working days, Saturdays and Sundays.
Pic. 9 Window of time periods choosing.
It is needed to set the beginning and the end
of given time period and value with which
the preset temperature will be reduced.
