(radiators)
ON
–
enables operation of the circuit,
OFF
–
disables operation of the circuit, then all parameters
related to this circuit are invisible and inactive.
Control method
Constant value,
Weather control
Weather
control
Constant value
–
constant preset temperature of water in
nonadjustable circuit is maintained.
Weather control
–
water preset temperature of water in the circuit
is set with consideration to external temperature sensor readings.
Parameter is invisible if no external temperature sensor is
connected. When the weather temperature sensor is defective or
not connected, the setting of the
Control method
is permanently
changed to
Constant value
.

Settings related to weather control.
➢
Heat curve
The graph
depends on four
external
temperatures
Selection in the form of a heating curve graph on which the set
temperature of the heating circuit for four intermediate weather
temperatures is set: 10°C, 0°C,
-
10°C and
-
20°C.
To set the preset temperature, touch the corresponding point and
move it up or down. The higher heating temperature, the higher
temperature of water in the heating circuit. Parameter becomes
available when
Control method
=
Weather control
. Detailed
description can be found in point 10.4
➢
Curve parallel
shift
-
20…20
0°C
Parameter enables to readjust the heating curve. Parameter
becomes available when
Control method
=
Weather control
.
➢
Thermostat
NO,YES
YES
Parameter assigns a thermostat to the heating circuit.
OFF
–
room temperature has no effect on the heating circuit,
ON
–
the thermostat has an effect on the preset water
temperature in the heating circuit, reducing it or completely
switching off the heating circuit.

Reduce constant
water temperature

10°C
When
Control method
=
Constant value
, then a constant preset
temperature of water in the circuit is decreased for regulation
modes: NIGHT, AUTO.
➢
Reduce water temp.
by thermostat
0…80
10°C
The parameter is applicable only when
Thermostat
=
ON
.
Exceeding a room preset temperature causes a decrease of
preset temperature of water in the heating circuit
Reduce water
temp. by thermostat
.
Decreasing the preset temperature takes place at the moment of
opening thermostat contact. The preset temperature of the water
in the heating circuit is not changed when the
Reduce water

= 0. The parameter disappears when the
Thermostat
=
OFF
.
Pump lock by
thermostat
NO, YES
YES
NO
–
the thermostat has no effect on the circuit operation,
YES
–
the circuit will be switched off when the temperature preset
on the thermostat is reached.
Circuit name
A…Z
H1
Enables changing name H1 circuit.
Note: H1 circuit is a nonadjustable circuit. Due to this the H1 circuit preset temperature
is the same as the heating source preset temperature. Therefore settings concerning
heat source have a direct effect in H1 circuit. The nonadjustable H1 circuit preset
temperature will be automatically increased in order to guarantee heat for H2 and H3
adjustable circuits.
