smart Econ - emz-HCW - 180116

Example of a low temperature heating circuit:
The possibility of specifying four points for the heating curve allows you to select different 'bends' of
the heating curve for different outdoor temperature ranges and to optimally adapt your system to the
respective conditions (building insulation, etc.).
Note:
Points P1 to P4 must follow each other in order and give a repetitively falling heating curve.
This means that P1 is at the lowest outdoor temperature, P2 at the next higher, P3 at the next, P4 at
the highest outdoor temperature.The temperature values must differ by at least 1°C.
The same applies vice versa for the flow temperatures, P1 starting with the highest value, then
decreasing.Two flow temperatures can be the same.
Using the smart Econ room controller
The flow temperature can be controlled with one or more room controllers depending on the room
temperature.However, operation without a room controller is also possible.
The control function of the room controllers can be configured as follows:
Outdoor temperature-guided control without remote setting
No room controller is installed in this variant.
The heating circuit runs in the ›AUTOMATIC‹ operating mode as soon as the outdoor temperature
drops below the preset limits.(Heating limit during the day e.g. 18°C, heating limit at night e.g. 3°C).
The outdoor temperature-controlled flow temperature is influenced by the room setpoint tempera-
ture.The reference temperature is 20 °C, higher or lower values increase or decrease the flow tem-
perature.
Outdoor temperature-guided control with remote setting
The heating circuit runs in the ›AUTOMATIC‹ operating mode as soon as the moderated outdoor
temperature drops below the preset limits.(Heating limit during the day e.g. 18°C, heating limit at
night e.g. 3°C).
The outdoor temperature-controlled flow temperature is influenced by the room setpoint tempera-
ture.The reference temperature for the heating curve is 20 °C, higher or lower values increase or
decrease the flow temperature.
A room controller is used to change the set room temperature in the control room.
