The room thermostats are delivered with a fixed set of applications. The relevant
application is selected and activated during commissioning using one of the
following tools:
· Synco ACS
· ETS5
· Local DIP switch and HMI
Functions
· Room temperature control via built-in temperature sensor or external room
temperature / return air temperature sensor

or bus, or manually)
· Selection of applications via DIP switches or commissioning tool
· Selection of operating mode via touch screen
· Temporary Comfort mode extension
· 1- or 3-speed fan control (automatically or manually)
· Display of current room temperature or setpoint in °C and/or °F
· Minimum and maximum limitation of room temperature setpoint
· Keylock function: unlock, total lock and setpoint
· 2 multifunctional inputs, freely selectable for:
- Window contact
- Presence detector
- External room temperature or return air temperature sensor
- Fault input
- Monitor input for temperature sensor or switch state
- Sensor for automatic heating / cooling changeover (RDF…)
- Dew point sensor (RDF…)
