Technical data

Functions
• Room temperature control via built-in temperature sensor or external room
temperature / return air temperature sensor
• Changeover between heating and cooling mode (automatic via local sensor or
bus, or manual)
• Selection of applications via DIP switches or commissioning tool (ACS, ETS)
• Select operating mode via operating mode button on the thermostat
• Parameters download with commissioning tool (ACS, ETS)
• Temporary Comfort mode extension
• Single speed, 3-speed or DC 0...10 V fan control (automatic or manual)
• Display of current room temperature or setpoint in °C and/or °F
• Minimum and maximum limitation of room temperature setpoint
• Button lock (automatic or manual)
• 3 multifunctional inputs, freely selectable for:
− Operating mode switchover contact (keycard, window contact, etc.)
− Sensor for automatic heating / cooling changeover
− External room temperature or return air temperature sensor
− Dewpoint sensor
− Electric heater enable
− Fault input
− Monitor input for temperature sensor or switch status
− Supply air temperature sensor (RDG160KN)
• Advanced fan control function, e.g. fan kick, fan start delay, selectable fan
operation (enable, disable or depending on heating or cooling mode)
• Purge function together with 2-port valve in a 2-pipe changeover system
• Reminder to clean fan filters
• Floor heating temperature limitation
• Minimum and maximum supply air temperature limitation (RDG160KN)
