 set HUW priority, using the Priority
parameter - in this case, the CH pump is
deactivated to speed up filling of the
HUW tank.
 set simultaneous operation of the CH and
HUW pump, using parameter No priority.
8.11 Setting HUW preset
temperature
Preset HUW temperature is defined by
parameter:
HUW settings
→
HUW preset temp.
8.12 HUW container hysteresis
Below HUW preset temp. – HUW container
hysteresis starts HUW pump to load the HUW
container.
After setting a low hysteresis value,
HUW pump will run faster when
HUW temperature falls.
8.13 HUW circulation
The settings can be found in:
HUW Settings
→
Schedule - circulation
pumps
and
Service settings
→
CH and HUW settings
Setting of circulating pump control is
analogical to night decrease setting.
Circulating pump switches on in selected
time intervals. In disregarded time intervals
circulating pump will start and remain in
operation for the period of time set in
Circulating pump operation time , then will
stop and remain out of operation for the
period of time set in Circulating pump
standstill time.
8.14 Enabling the SUMMER function
In order to activate the SUMMER function,
which enables to load the HUW tank in the
summer, without the need for activating the
CH system and mixer cycles, set the
parameter SUMMER mode to Summer.
Summer/Winter
→
SUMMER mode
In Summer mode, all heat
receivers may be shut off, so
before enabling it please make
sure that the boiler does not
overheat.
If the weather sensor is connected SUMMER
function can be activated automatically with
the Auto parameter including settings for
SUMMER mode act. temperature, SUMMER
mode deact. temperature.
8.15 Disinfection HUW container
The regulator has a function of automatic,
periodic heating of HUW container to 70°C to
eliminate bacterial flora from the HUW
container.
Keep the tenants informed of
activating the disinfection function
as there is risk of being burnt with
hot usable water.
The regulator increases the HUW container
temperature once a week, at 2:00 a.m.
Monday. After 10 minutes of maintaining the
temperature at 70°C, the HUW pump is
switched off and the boiler returns to normal
operation. Do not activate the disinfection
function when the HUW support is off.
8.16 Mixer circuits settings
Settings for the first mixer circuit can be
found in the menu: Mixer 1 settings
Settings for other mixers can be accessed in
next menu items and they are identical for
each circuit.
Settings for mixer without weather
sensor
It is necessary to manually set the required
water temperature in the heating mixer
circuit using parameter Preset mixer temp.,
e.g. at a value of 50°C. The value should
allow
to obtain the required room
temperature.
After connecting room thermostat, it is
necessary to set a value of decrease in
preset mixer temperature by thermostat
(parameters Mixer room therm.) e.g. at 5°C.
This value should be selected by trial and
error. The room thermostat can be a
traditional thermostat (NO-NC), or room
panel ecoSTER TOUCH. Upon activation of
the thermostat, the preset mixer circuit
temperature will be decreased, which, if
proper decrease value is selected, will stop
growth of temperature in the heated room.
