3.1.4.1 Low voltage terminal block (12 pole; 3.5mm spacing)
Note: The parameters are set up in Visionline; see the section To set up a thermostat profile for details.
Note:
For connection examples, click the links in the left column of Table 1 below.
Switch output
Warning: The switch output must not be used to switch the mains voltage.
Max 24V AC/DC, SELV, max 0.1A
Potential free switch output
Primary function: contact closed when the room is occupied; can e.g. be used for
giving a signal to a light control system
Note:
This is a switch output only; no voltages are output.
Alternative use of this output (e.g. use for intelligent switch and welcome scene)
must be set up in Visionline.
Proportional
output
(0-10V)
Outputs an analog voltage between 0V and 10V, where 0V is off and 10V is max
on.
Note:
This is to control actuators with a 0-10V control input*.
Cool: output to a proportional cool actuator
GND: common reference for the heat and cool outputs
Heat: output to a proportional heat actuator
*) Some actuators require other voltages, e.g. 2-10V or 0-5V.
Extra input Important: Do not apply any voltage. This is an input for a switch,
connected between the input and the GND terminal.
Primary function: Used as input from a card switch or a wired motion sensor
Alternative function: Input for 2-pipe temperature sensor (hot/cold water); this
sensor can either be a bimetal switch (open or closed depending on the
temperature it senses) or a 1k NTC resistor connected between this input and the
GND terminal. The 1k NTC resistor is a temperature-depending resistor, giving an
analog value determined by the temperature it senses. Note:
If the 2-pipe
temperature sensor is used, it is not possible to have a wired motion sensor.
Exterior door Important: Do not apply any voltage. This is an input for a switch,
connected between the input and the GND terminal.
Used as input from a switch mounted on an exterior door or window;
will turn the AC off when the door/window is open
Interior door Important: Do not apply any voltage. This is an input for a switch,
connected between the input and the GND terminal.
Used as input from a switch mounted on an interior door;
applicable when no VingCard online lock is installed
RS-485 (not in
use)
For communication with other equipment (e.g. light control equipment)
using the RS-485 standard
A shielded twisted pair cable, made for this communication standard,
must be used
A = non-inverting pin
B = inverting pin
C = common
