13.1 H1 circuit service settings
Direct circuit (nonadjustable)
Name Range** Setting** Description
Support ON (radiators),OFF
ON
(radiators)
ON (Radiators)
– enables operation of the circuit,
OFF
– disables operation of the circuit,
Adjustment method Fixed value, weather weather
fixed value
– constant preset temperature of water in
nonadjustable circuit is maintained
weather
– 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.
Weather control

Heating curve
0,1 … 4,0
1,2
The higher heating temperature, the higher temperature of water in
the heating circuit. Recommended settings:
floor heating:
0,2 -0,6
radiator heating: 1,0 - 1,6
Parameter becomes available when Adjustment method = weather .

heating curve shift -
20 … 20 °C
Parameter enables to readjust the heating curve.
Parameter becomes available when
Adjustment method = weather .

Constant water preset
temperature
20
… 85
45
°C
When Adjustment method = fixed value, heat source is disabled
when constant water preset temperature is reached. Source is
enabled again after the temperature drops by heat source
hysteresis value. Parameter is not available if Adjustment method =
weather .

Decreasing constant
water temperature
0…80 10°C
When Regulation method = constant value, then a constant set
temperature of water in the circuit is decreased for regulation
modes: NIGHT, AUTO, OUTSIDE HOME, HOLIDAY.

Room thermostat
selection
No
Panel 1
T1
…T3
Panel 1
Parameter assigns a room thermostat to the heating circuit.
No
– room temperature has no effect on the heating circuit,
Panel 1
– room temperature readings are received from the control
panel and they have an effect on a preset temperature of water in
th
e heating circuit. Name “Panel 1” can be changed in the main
menu to, e.g. “Living room” in case the panel is assembled in a
living room.
T1
… T3 – the controller receives ON/OFF signal from the universal
room thermostat. Caution: after using the universal room thermostat
connected to controller terminals, there is no further possibility of
correcting temperature of water in the circuit from the room
temperature! Therefore it is recommended to use the control panel
as a room thermostat.

The
correction
Correction
Reduction
– exceeding a room preset temperature causes a
decrease of preset temperature of water in the heating circuit by
Water temperature reduction from thermostat value.
Correction
– exceeding a room preset temperature causes a
temperature correction of water in the heating circuit. Correction is
proportional to a
temperature correction value and to a difference
between preset and measured room temperature.
Thermostat + correction
– exceeding a room preset temperature
causes a temperature correction of water in the heating circuit and
decrease of preset temperature of water in the heating circuit by
Water temperature reduction from thermostat value. The correction
is proportional to the parameter value room temperature correction
and proportional to the temperature difference between the set
temperature and the measured room temperature.

Room temperature
correction
0
…100
20
The higher parameter value the higher correction of set temperature
in the heat circuit.
Set water temperature in the heat circuit will be corrected by delT
value:
delT = (TsetR
– TmR)*
temperature correction / 10,
where:
TsetR - set room temperature,
TmR - measured room temperature.
Set temperature of water in the heat circuit will not be corrected in
