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
• ETS
• Local DIP switch and HMI
• Room temperature control via built-in temperature sensor or external room
temperature / return air temperature sensor.
• Changeover between heating and cooling mode (automatically via local sensor
or bus, or manually).
• Selection of applications via DIP switches or commissioning tool.
• Selection of operating mode via operating mode button on the thermostat.
