3.4. Relay connections
The Color Control GX has potential-free Normally Open (NO) relay functionality. The function of the relay can be set via the GX
menu, Settings → Relay → Function.
In addition to manual and temperature [48]-related triggering, it can also be used as an alarm [37], generator start/stop [100] or
tank pump [37] relay.
If the relay function is configured as an Alarm relay, it is possible to reverse the polarity of the relay via an additional menu. The
default setting is Normally open. Please note that reversing the polarity to Normally closed will result in a slightly higher current
consumption of the GX device.
