6.2 Connection diagrams
Connection workflow:
● Select fan control type: DC, 1-speed or 3-speed fan
● Select application type, e.g. 4-pipe
● Columns V1, V2, V3, V4 show the output types (e.g. for 4-pipe: YH for heating
and YC for cooling) as well the available control signals
● Select the requested control output signals (e.g. 2-pos for heating, 2-pos for
cooling)
● Equipment V1, V2 etc. stands for the connected equipment on each terminal,
e.g. 4-pipe with outputs of 2-pos and 2-pos, V1 (valve actuator) connects to Y1
and V2 (valve actuator) to Y2
● "2-pos" can be used for control signal On/Off and PWM
● For universal applications, fan function needs to be switched off via P350
