Functions · 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. · Temporary Comfort mode extension. · 1-speed or 3-speed fan control (automatically or manually).
Applications The thermostats support the following applications, which can be configured using the DIP switches on the inner side of the thermostat's front panel or a commissioning tool. Remote configuration All DIP switches need to be set to OFF (remote configuration, factory setting) to select an application via commissioning tool.

Mechanical design The thermostats consist of 2 parts: · Front panel with electronics, operating elements and built-in room temperature sensor. · Mounting base with power electronics. The rear of the mounting base contains the screw terminals. Slide the front panel in the mounting base and snap on.
Engineering notes See "Reference documentation" on page 15 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 Mount the room thermostat on a conduit box. 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 front panel 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 parameters The thermostat's control parameters can be set to ensure optimum performance of the entire system (see basic documentation P3171). The parameters can be adjusted using - Local HMI - Synco ACS - ETS Control sequence · The control sequence may need to be set via parameter P01 depending on the application. The factory setting for the 2-pipe application is "Cooling only"; and "Heating and Cooling" for the 4-pipe application.
