CE1B3076.2en / 25 Feb 2010 Subject to change Siemens Building Technologies s Operating Instructions RDF400... RDF400... – the room thermostat that allows you to set the ideal room temperature. The thermostat provides Comfort, Energy Saving, and Protection mode and can operate in Auto timer mode using 8 programmable time schedules. The fan operates either in Auto mode or at a speed selected in Manual mode. You can either take advantage of the thermostat's factory settings or adjust it as needed. Display Protection mode Auto Timer mode Comfort mode Energy Saving mode Measured room temperature, setpoints and parameters Current time of day Actual room temperature Fault indicator * Condensation in the room * Cooling demand / mode Heating demand / mode Electrical heater active Automatic fan Low fan speed Medium fan speed High fan speed Buttons are locked Weekday 1…7 (1 = Monday / 7 = Sunday) Operation and settings Operating mode button  **  **  View and set Auto-Timer-Programm Protection mode / system ON Colder / Warmer Fan mode button – Automatic fan ( ) – Manual fan ( ) Set time of day and weekday Confirm settings * Needs to be configured by your HVAC installer ** Needs to be enabled via parameter P02 Change room temperature + / – Press + or – to increase or decrease the current room temperature setpoint for Comfort mode. The thermostat changes to Comfort . The setting range is 5...40 °C, unless limited by parameters P09 and P10. Adjust fan speed / fan mode Press the button until you reach the desired fan mode. In Auto mode, the thermostat automatically selects the fan speed based on set- point and actual room temperature. The fan continues to run at low speed (factory setting) after the room temperature reaches the setpoint . In manual mode, the fan always runs at the speed that you select: Low fan speed Medium fan speed High fan speed For a single-speed fan, you can change the mode between and . Change thermostat operating Press operating mode button to change the operating mode display. In protection mode, the plant stops operating. However, if the room temperature drops below 8 °C, heating is switched on to protect the room against frost. Your HVAC installer can change the frost protection limit and set a heat pro- tection limit as needed: Changes made by installer:  Frost protection: ........... ˚C Heat protection: ........... ˚C In Comfort mode, the thermostat maintains the room temperature on the set- point which can be readjusted using the + and – buttons. In Energy Saving mode, the room temperature is maintained at a lower or higher setpoint, thus saving energy and money. Adjust parameters P11 and P12 to change the preselected setpoints. The thermostat can be set to Energy Saving mode either by pressing the ope- rating mode button if enabled (P02 = 2), or via an external signal (switch) such as window contact, keycard or presence detector. In Auto timer mode, the thermostat automatically switches between Comfort and Energy Saving mode according to the time schedule. Change from heating to cooling mode / Changeover between cooling and heating is either automatic using a heating / cooling changeover sensor or a remote changeover switch, or manual by pressing the operating mode button . No changeover is possible if the thermostat is configured for cooling only or heating only, (see parameter P01). Display for automatic changeover or heating only / cooling only: Heating valve is open Cooling valve is open Display for manual changeover: Thermostat is in heating mode Thermostat is in cooling mode CE1B3076.2en / 25 Feb 2010 Subject to change Siemens Building Technologies Setting time of day and weekday + – 24h  12 h + – 1.

Button lock Press operating mode button for 5 seconds to lock or unlock the buttons if manual button lock is configured (parameter P14 = 2). The thermostat automatically locks the buttons 30 seconds after the last adjustment if "Auto lock" is configured (P14 = 1). The key symbol indicates locked buttons. Reminder to clean filters and for external faults FIL * This message reminds you to clean your HVAC equipment filters. It is displayed after ………… “fan operating hours” and disappears when the thermostat is set to Protection ( ). * Needs to be configured by your HVAC installer Note: Energy saving mode The energy saving setpoints are factory-set to 15 °C for heating and 30 °C for cooling. Use parameters P11 and P12 to adjust the values. Important: You can set these setpoints to OFF; the thermostat then is inactive, i.e. no protective heating or cooling function.  Risk of frost! Commissioning You can adjust a number of control parameters to adapt the thermostat to your system and optimize control performance. You can do this during operation via the buttons on the thermostat. Control parameters Proceed as follows to change the most important control parameters: (Your HVAC installer can set additional parameters) + / – 1. Press the – and + buttons simultaneously at least 3 seconds. Release, and within 2 seconds, press + again for 3 seconds. "P01" is displayed. 2.

The current value of the selected parameter begins to flash, allowing you to change the value by repeatedly pressing + or –. 4. The next parameter is displayed when you press + and – again simultaneously. 5. Repeat steps 2 to 4 to display and change additional parameters. 6. Press + or – until “End” is displayed, and then press + and – simultaneously to save the change and exit parameter entry mode. 10 seconds after the last display or setting, all changes are saved and the thermostat will leave parameter setting mode.
