
Min. set return temperature
The boiler return temperature below which the electric actuator will close
the mixing valve.

Valve closing percentage
It is a value for opening the mixing valve during active return protection
function. This value is given in percentage. This value should be set in
such way, that the return temperature can raise. Attention: the return
protection function will work only in case when the set boiler temperature
will be set on sufficiently high value, otherwise there will be too many lock
ups of the actuator. Attention: The valve is locking up with the +-1% of
precision.
Min. boiler temp.
Minimal set temperature for the boiler, that can be edited by the user in
user menu and also a minimal temperature, that can be automatically set
by a controller e.g. from night decrease, weather control etc.
Max. boiler temp.
Maximal set temperature for the boiler, that can be edited by the user in
user menu and also a maximal temperature, that can be automatically set
by a controller e.g. from night decrease, weather control etc.
Boiler cooling temp.
Preventive boiler cooling temperature. When this temperature is
exceeded, the regulator switches on the hot usable water pump and opens
the mixer circuits in order to cool the boiler down. The regulator will turn
the hot usable water pump when the temperature of this water exceeds
the maximum value. The regulator will not open the mixer circuit when
mixer support = floor On .
Thermostat select
The following options are available:
deactivated
(deactivates the effect of the room thermostat on the boiler’s
operation)
universal (enables a NO-NC room thermostat on terminals 42-43,
recommended for thermostats with hysteresis below 1K)
ecoSTER (this option is available when the ecoSTER TOUCH room panel
is connected, the signals on the status of the thermostat are sent from the
room panel)
Pump Off by thermostat
Available options:
No (the CH boiler pump is not switched off when the room thermostat is
activated)
YES (the CH boiler pump is switched off when the room thermostat is
activated)
14.3 CH and HUW
CH and HUW settings
CH pump activation temperature
This parameter decides on the temperature of boiler pump activation. It
secures the boiler against retting, that can occur when the boiler is being
cooled down with cold water from the installation. Attention: deactivation
of boiler
pump doesn’t guaranteed, that the boiler is secure against retting
and therefore corrosion. It is recommended to apply additional automatics
e.g. 4-way valve or 3-way thermostatic valve.
CH pump standstill when loading
HUW
It requires a HUW sensor to be plugged in. A prolonged HUW tank loading
can, with HUW priority activated, lead to excessive cooling down of CH
installation, because with these kind of settings the CH pump is switched
off. The parameter of pause time of CH pump preventing this by periodic
operation of CH pump while HUW tank loading. The CH pump will after
this time activate for fixed set time of 30s.
CH pump standstill time by
thermostat
When the temperature of the heated rooms is reached (the contact of the
room thermostat is open), the CH pump is stopped for the
CH pump
standstill time from the thermostat , after which the CH pump operation
time from the thermostat is activated. Note: The following conditions must
be met in order to stop the pump via the room thermostat:
Boiler room thermostat selection
≠ deactivated
Pump Off by thermostat = YES
CH pump operation time by
thermostat
Min. HUW temperature
It requires a HUW sensor to be plugged in. This parameter can be used
for limitation of possibility to choose too low value of HUW set
temperature.
Max. HUW temperature
It requires a HUW sensor to be plugged in. This parameter decides on
which maximum temperature will the HUW container be heated during
