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
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
For details concerning connection of peripheral devices and setting of the DIP
switches please refer to the mounting instructions, M3182 [3]:
