Operation
Displaying minimum and maximum values
To read out or reset the stored CO2 and temperature minimum and maximum values use the optional display &
programming module OPA-S.
1.
Remove SRC housing from the back plate (see SRC-C1T1 installation sheet no. 70-000809
2.
Connect the OPA-S operating device to the OPA-
S connector on the SRC (see section “
” on
page 4). The measured CO2 and temperature value is displayed.
3.
Press the “UP” key to see the maximum values or the “DOWN” key to see the minimum values.
4.
To reset the minimum value, press the “DOWN” key for at least 5 seconds and wait unti
l the value changes.
5.
To reset the maximum value, press the “UP” key for at least 5 seconds and wait until the value changes.
Relay output
The relay output signals the CO2 level of the room air. The relay is off if the CO2 level is low and on if the CO2 level is
high. The output can be used to control a ventilation system. The levels may be programmed (see section
, page 6).
The diagram shows how the relay output corresponds to CO2 level and air quality LED.
Configuration
Output signal configuration, Jumper settings
The analog output signal type for the analog output AO1 and AO2 is factory set to VDC.
The signal range for the analog output AO1 and AO2 may be set with jumper
JP2
.
JP2
will
only operate if the output range specified with output parameter
the default value of 0…100%. With any other setting the position of
JP2
has no influence
and the signal range defined with the output parameters applies.
For j
umper location see section “
” on page
Parameter configuration
The transmitter can be adapted to fit perfectly into any application by adjusting the software parameters. The parameters
are set with the operation terminals OPA-S. The OPA-S may also be used as remote indicator.
NOTE: For the correct display of data, version 1.7 or grater of OPA-S is required.
OPA-S operation
1.
Remove SRC housing from the back plate (see SRC-C1T1 installation sheet no. 70-000809
2.
Connect the OPA-S operating device to the OPA-
S connector on the SRC (see section “
” on
page 4). The measured CO2 value is displayed.
3.
Use the "UP" and "DOWN" keys to set the password "0009" and confirm with the "RIGHT" key.
4.
Select "IP SEL
(Input Parameter) or “OP SEL” (Output Parameter) with "UP" and "DOWN" and confirm with the
"RIGHT" key. The first parameter is displayed.
5.
Use the "UP" and "DOWN" key to switch to the desired parameter. After pressing the "RIGHT" key adjust the
parameter value with the "UP" and "DOWN" keys. Confirm the setting with the "RIGHT" key.
6.
Complete parameter setting by pressing the left "ON/OFF" key twice. The measured CO2 value is displayed.
Important
In order for the TOA to apply the new settings correctly, the parameter setting must be completed with the left
"ON/OFF" key!
Detailed information on the OPA-S can be found on the website
product page under "Downloads".
