The controller regulates temperature of the
HUW
container, providing that the
temperature sensor is connected. When the
sensor is disconnected – the information
about it is displayed in the main window. By
selecting:
HUW settings
→
HUW Pump mode the
user is able to:
 deactivate feeding the HUW container,
parameter Off,
 setting HUW priority, by parameter
Priority – then CH pump is deactivated to
load the HUW container quicker,
 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:

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 container.
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
Attention: when boiler operates
without heating buffer and the
controller is switched into SUMMER
mode,
than Standard mode
operation is recommended.
It is not allowed to activate
function summer when HW 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
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.
