SEPARATE WORK OF THE DIRECT AND MIXING HEATING CIRCUIT
When using the KMS controller and the direct and mixing heating circuit are active
(scheme 407) you can chose on which heating circuit the coding switches S2 and S3 (on
the back of the DD2 room unit) will have effect.
The DD2 room unit is controlling the work of the direct and mixing heating
circuit.
The DD2 room unit is controlling the work of the direct heating circuit.

The DD2 room unit is showing the data of the controller.
Usage of the room temperature sensor is set independent from the coding
switch S2 and S3 setting.
CONNECTING THE GAS BOILER
Gas boilers can be connected to the controller KMS in three different ways::
1. With module JMP1 or JMP2 and connecting the boiler temperature sensor KF.
This application allows sliding power regulation of Junkers and Vaillant gas boilers.
2. With connection to outputs A.1 and
A.2 for burner regulation and connect-
ing the boiler temperature sensor KF.
In this case the boiler is 2-point (ON/
OFF) regulated and can be used by
all kinds of boilers. Also the burner
operation hysteresis - parameter S5.6
must be set to 10 K or higher.
3. With connection to outputs A.1 and
A.2 for burner regulation - parameter
S5.3=0.
Boiler temperature sensor connection
is not necessary. In this case control-
ler KMS permanently switches on the
boiler, when needed to. Working tem-
perature is set on the boiler controller.
