B
Set the highest and lowest permitted temperature for T1. Ensure that
the value corresponds with the selected curve and possible curve
adjustments.

does not
exceed the permitted value for the type of floor used.

>> Regulator settings
The mixing valve is controlled with PID regulator in order to reach the
flow set point value when there is a need. The signal determines how
much the opening of the mixing valve should change. It is calculated with
short time intervals.

>>> Mixing valve running time
B
Set the run time that is indicated on the mixing valve and indicate
value in number of minutes.
>>> Mixing valve fully closed
B
Set how many K ( °C) below the maximum permitted flow temperature
T1 the mixing valve is to be fully closed. The maximum flow
temperature is different depending on the type of heating system
(radiator or underfloor). With an underfloor system, the mixing valve
should be fully closed at 45 °C-2K=43 °C (with factory settings).
>>> Mixing valve start closing
B
Set how many K ( °C) below the value for fully closed mixing valve the
closure of the mixing valve should begin. The result is 43 °C-2K=41 °C
(with the factory settings for underfloor heating).

Table 69 Mixing valve running time
If there is no time indication on the mixing valve, run it
manually (
Æ
Chapter 16.7 ) and measure how long it
takes to go from fully closed to a fully open mixing valve
(the mixing valve stops sounding and the endposition
switch switches off).
