9) VE.Direct port RX pin mode (setting 57)
Value Description
0 Remote on/off (default). Can be used for on-off control by a VE.Bus BMS (instead of
connecting the BMS to the remote on-off port.
VE.Direct non-inverting remote on/off cable needed. (ASS030550310)
1 No function.
2 The RX pin can de-energize the relay (relay off), if relay function 10 of setting 11 has
3 been set (see note 5, value 10). The load control options (setting 35) remain valid.
In other words, a AND function is created: both the load control and the RX pin must
be high (value=2) or low (value=3) to energize the relay.
10) VE.Direct port TX pin mode (setting 58)
Value Description
0 Normal VE.Direct communication (default)
For example to communicate with a Color Control panel (VE.Direct cable needed)
1 Pulse every 0.01kWh
2 Light dimming control (pwm normal) TX digital output cable needed
