Type Description

N 502 N 502 combination switch actuators

• Outputs identical or can be individually configured

• Operating mode can be adjusted for each output

(normal mode, timer mode)

• Switching behavior can be adjusted for each output

(NO contact/NC contact)

• Adjustable ON/OFF delay

• Selectable logic operation (AND/OR) of two communication

objects and adjustable start value of operation in the event of

bus power recovery

after modification

• Integrated 8-bit scene control and integration of each channel

in up to 8 scenes

• Unchanged switching state of all outputs during power failure

• Switching state can be adjusted for each output after system

recovery

• Transmission of the output status object on request or if the

switching state changes, optionally with automatic switchover

of the return valve between heating and cooling mode or with

switchover of the return valve over an object
