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...
Applications The thermostats support the following applications, which can be configured using the DIP switches at the rear of the unit or a commissioning tool. DIP switches 1...3 need to be set to OFF (remote configuration, factory setting) to select an application via commissioning tool.

Engineering notes See the "Reference documentation", page 17 for information on how to engineer the KNX bus (topology, bus repeaters, etc.) and how to select and dimension connecting cables for supply voltage and field devices. Mounting and installation Do not mount on a wall in niches or bookshelves, behind curtains, above or near heat sources, or exposed to direct solar radiation. Mount about 1.5 m above the floor.
Commissioning notes Applications The room thermostats are delivered with a fixed set of applications. Select and activate the relevant application during commissioning using one of the following tools: − Local DIP switch and HMI − Synco ACS − ETS Set the DIP switches before snapping the thermostat to the mounting plate, if you want to select an application via DIP switches. All DIP switches need to be set to “OFF” ("remote configuration"), if you want to select an application via commissioning tool.
Control sequence • The control sequence may need to be set via parameter P01 depending on the application. The factory setting is as follows: Application 2-pipe and chilled / heated ceiling, and 2-stage 4-pipe, chilled ceiling and radiator Factory setting P01 1 = Cooling only 4 = Heating and cooling Calibrate sensor • Recalibrate the temperature sensor if the room temperature displayed on the thermostat does not match the room temperature measured (after min. 1 hour of operation).
