You can connect an external NTC10K sensor to the RI1 and RI2 inputs for various control and
display tasks (optionally, AI1 and AI2 as analogue inputs 0...10V).
Use the parameters "Room Sensor Text", "Floor Sensor Text" and "Aux. Sensor Text"
to release and adjust the display.
Use the parameters "RI1 Mode" and "RI2 Mode" to configure both channels.
The following configuration options are available:
• Disabled (default)
• Room (NTC10K)
Enables main temperature control with a connected NTC10K sensor.
The integrated temperature sensor is separate from the control.
Use the parameter "Room Sensor Text" to release and adjust the display.
• Floor (NTC10K)
The input is used for limit value control (see chapter "Limit value control").
If RI1 and RI2 were both configured for a floor, RI1 is prioritised.
Use the parameter "Floor Sensor Text" to release and adjust the display.
• AUX control circuit (NTC10K)
Releases the input for the auxiliary control circuit in a second zone (see chapter "AUX control circuit").
If RI1 and RI2 were both configured for outdoor temperature control, RI1 is prioritised.
Use the parameter "Aux Sensor Text" to release and adjust the display.
• Changeover (NTC10K, heating/cooling)
The input is used to automatically switch into changeover mode (see chapter "Changeover").
The temperature value is not displayed.
• Bus (NTC10K)
The input is available for temperature recording using the connected NTC10K sensor via the bus
(no control function). The temperature value is not displayed.
• Bus (AI option, 0...10V)
The 0...10 V input signal is converted to 0...100 % and can be queried via the bus.
• CO2 (AI option, 0...10V)
The 0...10 V input signal is converted into 0...2,000ppm.
The measurement is available via the bus for monitoring purposes and automatically
linked to the CO2 control (see chapter "CO2 control circuit").
The CO2 value is not displayed.
• Main control circuit (AI option, 0...10V)
The 0...10 V input signal is converted into 0...50 °C.
The measurement is available via the bus for monitoring purposes and automatically
linked to the temperature main control circuit.
Use the parameter "Room Sensor Text" to release and adjust the display.
• Close for ECO (DI mode)
Voltage-free digital input for priority switching to ECO if closed.
• Open for ECO (DI mode)
Voltage-free digital input for priority switching to ECO if open.
• Close for OFF (DI mode)
Voltage-free digital input for priority switching to OFF if closed.
• Open for OFF (DI mode)
Voltage-free digital input for priority switching to OFF if open.
• Condensation protection (DI mode)
The input is used for a condensation resistance sensor to disable cooling if condensation is detected.
NOTE: If the input is used for condensation monitoring, do not set the digital input mode
to "disable cooling" as the digital input configuration is prioritised.
• Bus DI
Voltage-free digital input to read from the bus.
NOTE: Resistance inputs used as digital inputs work with a delay of approx. 10 s
and are not effective immediately. Therefore, they are not suitable for rapid
switching as their effect only comes after an inherent delay.
