• set simultaneous operation of CH and
HUW pump with the parameter No
priority.
8.14 HUW preset temperature settings
Preset temperature HUW is defined by
parameter:
HUW settings → Preset HUW temp.
8.15 Hysteresis of HUW
Below temperature Preset HUW temp. minus
HUW hysteresis the HUW pump will activate
to feed the HUW tank.
By small hysteresis value HUW
pump will activate faster after HUW
temperature decrease.
8.16 SUMMER function start-up
To activate SUMMER function which allows
feeding the silo during summer, without
necessity to activate CH installation and
mixers periods, it is required to set the
menu:
Summer/Winter → SUMMER mode for
Summer
It is not allowed to activate
function Summer when HUW pump
is disconnected or damaged.
Function SUMMER can be activated
automatically, on the basis of readings from
weather sensor. Use following parameters to
activate this function:
Summer/Winter → SUMMER Mode →
Auto
If the automatic detection of summer mode
is switched on, user can set the parameters:
Activ. temperature SUMMER, so outdoor
temp. above which the summer mode will be
switched on and Deactv. temperature
SUMMER , so outdoor temp. below which the
SUMMER mode will be switched off.
8.17 HUW container disinfection
The controller can automatically, periodically
make HUW container warm up to 70ºC. It is
done to remove bacterial flora.
It is absolutely important to inform
all the inmates about activating the
disinfection function. There is a
danger of scalding with hot water.
Once a week at night, in Monday at 2 a.m.
the controller increases temperature of HUW
container. After 10minutes of keeping the
silo at 70ºC the HUW pump is deactivated
and the silo returns to its normal operation.
It is not advisable to activate disinfection
function while the service of HUW is
deactivated.
8.18 Mixer circle settings
Mixer circuit support is only
available when an additional
expansion module B is connected.
Settings of first mixer circle are in the menu:
Mixer 1 settings
Settings for other mixers are in following
sections of the menu and are identical in
each cycle.
• Mixer settings without weather
sensor
It is required to set manually desired
temperature in mixer’s heating cycle using
parameter Preset mixer temp., e.g. 50ºC.
Such should be a value to provide required
room temperature. After connecting a room
thermostat, value of decline in preset mixer
temperature from thermostat should be set.
(parameters Mixer room thermostat, e.g.
5ºC. This value should be chosen
experimentally. A room thermostat can be a
traditional one or a room panel. After
activating the thermostat, mixer preset
temperature will be reduced. When this value
is reduced correctly then room temperature
increase will be stopped.
• Mixer settings with weather sensor
setting
Set parameter Weather mixer control in
position on. Adjust weather curve according
to point 8.19. Using parameter Curve shift
set required room temperature according to
formula:
Required room temperature = 20°C +
heating curve shift.
Example:
To reach room temperature 25°C value of
heating curve shift must be set for 5°C. To
reach room temperature 18°C value of
heating curve shift must be set for -2°C.
