The relay output settings assign the appropriate functions.
None
Relay output with no function.
Circulating pump Q4
The connected pump serves as a DHW circulating pump. Operation of the pump can be
scheduled as required on operating page DHW, operating line Circulating pump release
(1660).
DHW El imm heater DHW K6
Using the connected electric immersion heater, the DHW can be heated according to
operating page DHW storage tank (El imm heater optg mode (5060), El immersion
heater release (5061) and El immersion heater control (5062)).
Warning!
The electric immersion heater must be equipped with a safety limit thermostat!

Alarm output K10
The alarm relay signals faults, should they occur. In the event of fault, the relay’s
contact closes after an adjustable Alarm delay (6612). When the fault is corrected, that
is, when the fault status is no longer present, the relay is deenergized with no delay.
The Syst messages alarm relay (6611) setting determines whether or not system errors
signaled via LPB are also capable of triggering the alarm relay.
Note!
If the fault cannot immediately be corrected, it is still possible to reset the alarm relay.
This is made on operating page Faults.
