Functions of the heating circuit

Remote control
Apart from measuring the room temperature, the Type 5257-5 Room Panel (Pt 1000 sensor)
provides the following opportunities of influencing the control process:
4
Selection of the operating mode:
4
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
When the remote room controller (room panel) is connected and activated, the corrected
Room temperature set point is shown.

Flash adaptation
A Type 5257-5 Room Panel must be connected for the Flash adaptation function.
The flash adaptation counteracts deviations in room temperature by reducing or raising the
flow temperature by up to 30 °C. The Cycle rate determines the time between each correc-
tion of the flow temperature set point by 1 °C.
The flash adaptation is deactivated when the parameter Cycle rate (P18) is set to 0. The
measured room temperature then does not have any affect on the flow temperature control.
Note!
We recommend setting the flash adaptation initially with a cycle rate of 10 minutes. Shorter
cycle rates are more likely to have a negative effect, particularly when cooling loads such as
drafts or an open window affect the control. Then the rooms may be temporarily overheated
when the cooling load is eliminated.
