Technische Alternative UVR 16x2 User Manual

Parameters
11
Parameters
These parameters are values and settings which are specified by the user only.
They are settings which allow the user to adjust the controller to match the properties of the user's
system. This menu may also be divided into further sub-menus, depending on the function.
Hystereses
Many parameters have adjustable start and stop differentials which have the effect of a switching
hysteresis.
Example:
Demand temperature in the Heating demand function
Demand is triggered at T.dem. set + Diff. on (= 61 °C); shutdown is triggered at T.dem. set + Diff. off
(= 69 °C).
The values of Diff. on and Diff. off can also be negative, but are always added to the set temperature.
Example of a negative Diff value:
Here, demand is triggered at T.dem. set + Diff. on (= 51 °C); shutdown is triggered at T.dem. set +
Diff. off (= 60 °C).
