Sensor Vari KNX 3L-TH-D
• Status: 19.10.2016 • Errors excepted. Subject to technical changes.
When using the control variable for a 4/6 way valve, the following applies:
0%...100% heating = 66%...100% control variable
OFF = 50% control variable
0%...100% cooling = 33%...0% control variable
6.15.1. Heating control level 1/2
If a heating control mode is configured, one or two setting sections for the heating le-
vels are displayed.
In the first level, heating is controlled by a PI controller which allows to either enter con-
trol parameters or select predetermined applications.
In the second level (therefore only in case of 2-stage heating), heating is controlled via
a PI or a 2-point-control.
In level 2, the setpoint difference between the two levels must also be specified, i.e. be-
low which setpoint deviation the second level is added.
PI control with control parameters:
This setting allows individual input of the parameters for PI control.
For heating and cooling
• separate control variables are used
• common control variables are used for
Level 1
• common control variables are used for
Level 2
• common control variables are used for
Level 1+2
