Siemens RDG400 Single-duct heating / cooling coil, DIP Y10 = … 10 10 … 0 V inverted, Position

4.7.3Control outputs overview

(setting via DIP 4 / 5 and parameters P46 / P47)

Control outputs

Application

Single duct

Single duct and electrical heater

Single duct and radiator / floor heating

Single-duct heating / cooling coil

ON/OFF (2-position)

Modulating PWM (2-position)

Modulating 3-position

Modulating DC 0 … 10 V

The function of the control outputs is set via DIP switches 4 and 5:

ON					ON					ON					ON
OFF					OFF					OFF					OFF
1	2	3	4	5	1	2	3	4	5	1	2	3	4	5	1	2	3	4	5

3181D101

DIP 4:		Y10 =	0 … 10 V	0 … 10 V	10 … 0 V inverted	10 … 0 V inv
DIP 5:	Y1 / Y2 =		2-position	3-position	2-position	3-position
Note		Y1, Y2:

If 2-position is selected, the factory setting is on/off.

If you want PWM (pulse width modulation), set parameter P46 to 2 = PWM.

P47:

•0 = VAV box DC 0 … 10 V control signal

•1 = VAV box : 3-position control signal
