4.7.1Applications and sequences

Application VAV	Sequences
Single duct	h ( \ ), c ( / )
Single duct & electrical heater	el.h + c (	\	/	)
Single duct & radiator	rad + c (	r\	/	),
Single duct with heat/cool coil	h + c ( \	/ )

4.7.2Sequences overview (setting via parameter P01)

The sequence can be set via parameter P01, if available.

The thermostats can be used in systems featuring:

•Heating only mode (P01=0)

•Cooling only mode (P01=1)

•Manual heating/cooling changeover (P01=2)

•Automatic heating/cooling changeover (P01=3)

•Heating and cooling mode (e.g. 4-pipe system) (P01=4)

The available modes depend on the application (selected via DIP switch, see section 4.5).
