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,
• by frosty weather room temperature is
appropriate and in warmer time is too low
– it is recommended to increase
parameter Curve 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
Curve 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.
8.20 Night decrease settings
description
In the controller it is possible to set time
intervals of preset temperature reduction for
boiler, heating cycles, HUW tank, circulation
pump. Time intervals 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. Decrease of preset
temperature in selected time intervals is
indicated by the symbol on the main
screen.
To activate time intervals, set the parameter
Night time decrease for the given heating
circuit to ON. The parameter Reduction value
set the temperature reduction, one for all
time intervals. Night time decreases can be
defined separately for every day of the week
set Schedule. Select temperature reduction
and beginning and end of respective time
interval. The time intervals for 24 hours are
fixed at 30min.
Time periods.
Above are examples of night-time decrease
the preset temperature lasting from 22:00
till 06:00 and the reduction from 09:00 to
15:00.
Attention, defining time periods
during one day must be started at
00:00!
Time period is omitted by setting
period reduction for value “0” even
if scope of hours is set in it.
8.21 Working according to schedule
In the controller is possible to switch on and
switch off the boiler at defined intervals. In
the absence of demand for heat, e.g. in
summer, one can disable the operation of the
boiler at a certain time and thus reduce fuel
consumption. To activate the time intervals
must set the parameter Off, in the menu:
Work acc. schedule → On at YES.
Switching on and off the boiler in the time
interval can be set for all on separate days of
the week in the Schedule.
Work according to the schedule is the same
as that night time decrease, point 8.20
8.22 Circulation pump control
Functionality of circular pump is available in
the menu (only after connecting the
additional module B):
Night time decrease → Circular pump.
