Flow temperature 10 °C: the heating circuit pump will be switched on for 10 minutes
at 6-hour intervals
Flow temperature 5 °C: the heating circuit pump runs continuously
Frost protection for the plant can be deactivated, if required.
Frost protection for the building acts as minimum room temperature limitation and pro-
tects the rooms from too low temperatures. It can be achieved with or without room
unit, provided the heating curve slope is correctly set.
Without room unit:
Attenuated outside temperature 5 °C: the control is switched on and the flow tem-
perature is controlled such that a room temperature of 5 °C will be maintained
Attenuated outside temperature >6 °C: the control is switched off
With room unit and quick setback active:
Room temperature 5 °C: the control is switched on and the flow temperature is
controlled such that a room temperature of 5 °C will be maintained
Room temperature >6 °C: the control is switched off
With room unit, without quick setback:
Same as without room unit
Frost protection for the building can be deactivated, if required.
Pump overrun: heating circuit pump and d.h.w. charging pump with six minutes overrun
Pump kick: all pumps are periodically switched on for one minute
When changing from the reduced temperature or protection mode to the normal tem-
perature, the room temperature setpoint is raised by 5 K. When the room temperature
reaches a level which lies 0.25 K below the setpoint of the normal temperature, boost
heating will be switched off.
Boost heating necessitates a room unit.
When changing from the normal temperature to the reduced temperature or protection
mode, the heating will be shut down until the respective room temperature setpoint is
reached.
Quick setback necessitates a room unit. This function can be deactivated, if required.
The ECO automatic energy saver controls the heating depending on demand. It
switches the heating off if permitted by outside temperature conditions while consider-
ing the actual, the attenuated and the composite outside temperature as well as the
adjustable heating limit.
The ECO automatic energy saver necessitates an outside sensor. It can be deactivat-
ed, if required.
Flow and boiler temperature: with a LG-Ni 1000 sensor
Outside temperature: with a LG-Ni 1000 or NTC 575 sensor; the controller identifies
the type of sensor used
Room temperature: with a room unit
The controller is equipped with a plug-in type time switch for entering a 24-hour or
weekly heating program. Backup is ensured.
The following choices are available:
Analog 24-hour time switch
Resolution of switching points: 15 minutes
Shortest on or off times: 15 minutes
Analog weekly time switch
Resolution of switching points: one hour
Shortest on or off times: two hours
Digital time switch
Any of these three time switches can also be fitted at a later time.
