"Open For" Configuration - The digital volt-free input can be used to activate ECO or OFF mode when
the contact opens. In this mode it can be connected to a window switch or door card switch.
Alarm Configuration - when the contact closes the "DI Contact Alarm" alarm message is displayed on
the screen.
Network option is selected when the digital input is used for monitoring purposes only.
Close for Night - when the contact closes the device goes to NIGHT MODE, where the user setpoint is
greyed out, the fan speed is set to a predetermined value, and where on return the fan speed goes to
Auto and the setpoint resets to Nominal setpoint.
Analogue 0-10Vdc Outputs
(SRI-71 Models only)
The SRI-71 models have 3 x 0..10Vdc Y1/Y2/Y3 analogue outputs. The configuration options for
outputs are:-
•
Setpoint; current setpoint is scaled over 0..10Vdc between Min/Max Setpoint Adjustments
•
CO2 (option); the CO2 reading is scaled over 0..10Vdc (as default 0..5,000ppm)
•
Humidity (option); the humidity measurement is scaled over 0..10Vdc (0..100%rH)
•
Sensor1 (RI1); RI1 reading is scaled over 0..10Vdc (as default 0..50°C = 0..100.0%)
•
Sensor2 (RI2); RI2 reading is scaled over 0..10Vdc (as default 0..50°C = 0..100.0%)
•
Sensor3 (Built-In Sensor); Built-In Sensor Reading is scaled over 0..10Vdc (as default 0..50°C =
0..100.0%)
•
Fan Speed; thecurrent selected Fan Speed is scaled over 0..10Vdc (1-speed: 0=0%, 1=100%;
2-speed: 0=0%, 1=50%, 2=100%; 3-speed: 0=0%, 1=33%, 2=66%, 3=100%; 6-speed: 0=0%,
1=17%, 2=33%, 3=50%, 4=66%, 5=83%, 6=100%)
Note:
Maximum Temperature Scale at 10V output, and maximum CO2 at 10V output can be
configured through Inputs/Outputs configuration menu.
Note:
Setpoint min and max output levels can be scaled using the AO SP Min and AO SP MAX
parameters.
Humidity Measurement (-RH
option)
The models with RH option have a 2%rH accurate humidity sensor for room space humidity
measurement. The humidity reading is displayed inside the SMALL ACTION CIRCLE (display as
default enabled, option to disable through configuration pages).
With MOD/BAC models the humidity reading is available over the communication network as a
network variable.
With SRI-71 models the humidity measurement can be sent to any of the analogue 0-10Vdc outputs
(Y1/Y2/Y3).
CO2 Measurement (-CO2
Option)
The models with CO2 option can monitor and measure the CO2 (Carbon Dioxide) levels. The
measured CO2 is shown on the display in the SMALL ACTION RING. The CO2 display can be
disabled in the Maintenance Mode if required.
With MOD/BAC-models the CO2 reading is available as a network variable.
With SRI-71 models the CO2 reading can be sent to the analogue Y1/Y2/Y3 outputs. The reading is
scaled over 0..5,000ppm.
Touchscreen Calibration
The touchscreen can be re-calibrated by pressing the screen on power-up, or when returning from the
System Maintenance Screen pressing the screen during the reboot. Calibrate the screen by swiping
to the all four edges of the screen and then press OK to accept the new settings.
Programming Schedule
(SRI-P70 Only)
The SRI-P70 user interfaces have up to five programmable time switching times. Each switching time
can be configured to switch the
Time Channel
network variable On/Off. The times can be set for
individual weekdays or can be switched 5+2 mode where the targets are set for WEEKDAYS or
WEEKENDS as a group.
The SCHEDULE OVERVIEW screen shows the current ON and OFF switching periods. By selecting
the day it is possible to adjust the switching times and On/Off setting.
NOTE: Switching from the 7 DAYS mode to 5+2 DAYS mode will set all weekday/weekend to the
group settings. When returning back to 7 DAYS mode the setting are required to be re-entered for
