Master clock
When your Velbus installation contains multiple modules with built-in clock (temperature controllers VMB1TC and control
panel VMB4PD) it is important that all clocks have the same time setting. This can be achieved by setting the clock of one
module as reference (master). This module will then synchronize the other module clocks every day. This function is
default disabled.
