3.2.4.1 Low voltage terminal block (Orion Thermostat-Zen-HV; 12 pole;
3.5mm spacing)
No t e : All parameters should be set up in VISIONLINE; see the section To set up a thermostat profile
for details. The Orion Service software can be used for testing parameters, but once a parameter
configuration is approved the parameter should be updated
in the thermostat profile in VISIONLINE.
No t e :
For connection examples, click the links in the left column of Table 1 below.
Solid state
switch output
Warning: The solid state switch output must not be used to
switch the mains voltage.
Max 30V AC /DC , max 0.1A
Potential free so thermostat states relay output
Primary function: contact closed when the room is occupied
Note:
This is a switch output only; no voltages are output.
Can e.g. be used for giving a signal to a light control system
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.
No t e :
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.
This must be set up in VISIONLINE; see details here
.
The minimum value is 0V, 1V or 2V. The maximum voltage is
configurable to 5V or 10V.
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 pipe sensor (hot/cold water); see details here
about setting up the extra input in VISIONLINE for this. The pipe 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
analogvaluedeterminedbythetemperatureitsenses.Thetypeofpipesensor
which is applicable must also be set up in VISIONLINE; see details here
(HVAC
heating) and here
(HVAC cooling).

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 VingC ard online lock is installed
RS-485 (not
implemented
yet)
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
