3. Define the third temperature sensor as an inside or outside thermometer.
NOTE FTS-3's data is used in controller calculations only if the sensor is defined as an inside
thermometer.
4. Press
Select
and go to Temperature > Temp.
5. Set the Target Temperature/Target THI.
6. If required, go to Calibration > T1.
7. Change the temperature output value. The system remembers the difference between the
system's calculation and the changed calibration value.
CAUTION Munters temperature sensors come pre-configured. Calibrate a sensor only if there
is a difference between the temperature displayed and the actual temperature.
8. Repeat the calibration for other temperature sensors.
NOTE If an error occurs with a temperature sensor, the information regarding the specific
sensor can be deleted from the
Calibration
menu. This is done by pressing <
PROG
>
when an invalid sensor’s field appears.
4.2.2 Configuring digital input sensors
This section details how to install the digital inputs. SMART-8C/3MD can support a water counter
and a wind speed reader. Each digital input is optional and independently installed.
NOTE Only perform the steps required for your particular installation.

Connect the digital input device(s) as shown in Figure 6, page 21.
1. Press
Select
and go to Test > Digital inputs.
2. Verify that the sensors are working properly.
3. If required, go to Calibration > Water counter and press
Prog
.
4. Change the water/pulse ratio.
5. Go to System > High Wind Speed and press
Prog
.
6. Choose value of high wind speed above which all devices turn off and curtain goes to
minimum position.
7. Press
Prog
.
8. Press
Select
.
4.3 Testing sensors and relays
This menu is used to test the sensors and relays as well as display software/hardware information.
CAUTION Entering Test screen pauses any control currently active. Exit the screen to restart
functions.
Pressing
Prog
when any of the relay items (FAN1, FAN2 or Cooling) is shown causes the controller
to pause. Pressing
Select
once again makes the controller resume operation.
1. Go to Test.
2. Choose the required test:
•
T1/T2/3
: Tests temperature sensors
•
Humidity
: Tests humidity sensor
•
Analog
: Test the analog output between
10.0 to 0.0V
•
Relay #
: Tests if relays 1 – 8 are on or off
