Functions of the heating circuit
6.7 Remote operation
Apart from measuring the room temperature, the Types 5257-5 and 5257-21 Room Panels
(Pt 1000 sensor) as well as Type 5244 Room Panel (PTC sensor) provide the following oppor-
tunities of influencing the control process:
−
Selecting the operating mode:
−
Automatic mode
−
Day mode
−
Night mode
−
Set point correction: during rated operation, the room temperature set point can be in-
creased or reduced by up to 5 °C using a continuously adjustable rotary knob.
With an activated room sensor, the measured room temperature is displayed when the re-
mote operation is connected and activated. Nevertheless, it is not used for control when ei-
ther the optimization,
adaptation
or
flash adaptation
function is activated.

6.8 Optimization
This function requires the use of a room sensor. Depending on the building characteristics,
the controller determines and adapts the required advance heating time (maximum 8 hours)
to ensure that the desired 'Day set point' (rated room temperature) has been reached in the
reference room when the time-of-use starts. During the advance heating period, the controller
heats with the max. flow temperature. This temperature is built up in steps of 10 °C. As soon
as the 'Day set point' has been reached, outdoor-temperature-compensated control is activat-
ed.
