∆ T
= preset temperature heat source –
temperature measured at sensor H1-S.
10.12 Weather control settings
Make weather control settings in order to
stabilize room temperature. Weather control
should be enabled separately for each
heating circuit in service settings. Weather
control is influenced by:
- heating curve setting,
- heating curve shift setting.
Preset temperature of water in heating circuit
is calculated automatically depending on the
external temperature value. Due to this,
proper selection of a heating curve will
guarantee room temperature stability –
independently of the external temperature.
This is why proper selection of a heating
curve is very important.
Heating curves.
Guidelines for proper setting of a heating
curve:
- floor heating
0,2 -0,6
- radiator heating 1,0 - 1,6
Guidelines for selecting a proper heating
curve:
- if at dropping external temperature, room
temperature increases, the selected heating
curve is too high,
- if at dropping external temperature, room
temperature also drops, the selected heating
curve is too low,
- if during frost, room temperature is proper
and too low when the weather is warmer, it
is recommended to increase heating curve
parallel shift and decrease the heating curve,
- if during frost, room temperature is too low
and too high when the weather is warmer, it
is recommended to decrease heating curve
parallel shift and increase the heating curve.
Poorly warmed buildings require setting
higher heating curves. Whereas for well
heating buildings, heating curve will have a
smaller value.
Preset temperature calculated from a heating
curve can be decreased or increased by the
controller outside maximum or minimum
temperature range for a particular object.
10.13 Room thermostat settings
In order to stabilize room temperature,
settings concerning room thermostat should
be made. Room thermostat complements
weather
control and corrects water
temperature in the heating circuit in case
room temperature is still improper. It is
recommended to use the control panel as a
room thermostat. Room thermostat should
be assigned to each heating circuit. In order
to do this, set the parameter:
menu
→
service settings
→
H1,H2,H3 circuit
→
Room thermostat selection = Panel 1
Next, set the parameter:
menu
→
service settings
→
H1,H2,H3 circuit
→
Room thermostat function = temperature
correction
Set the proper parameter value:
menu
→
service settings
→
H1,H2,H3 circuit
→
room temperature correction
The higher room temperature correction
parameter value, the higher correction of
preset temperature of water in the heating
circuit. Caution: setting too high room
temperature correction value can lead to
cyclical value fluctuations.
