Solar controlling element buffer K8
If several heat exchangers are used, the buffer storage tank must be set at the
respective relay output and, in addition, the type of solar controlling element must
be defined on OL 5840).
Solar pump external exchanger K9
For the external heat exchanger, solar pump "Ext heat exchanger K9" must be set
at the multifunctional relay output (ZX1).
Alarm output K10
The alarm relay signals faults, should they occur.
Switching on takes place with a delay of 2 minutes.
When the fault is corrected, that is, when the error message is no longer present,
the contact opens with no delay.
If the fault cannot immediately be corrected, it is still possible to reset the alarm
relay. This is made on operating page "Faults".
Storage tank transfer pump Q11
If the temperature level of the buffer storage tank is high enough, the DHW storage
tank can be charged by the buffer. This transfer can be made by means of transfer
pump Q11.
Buffer return valve Y15
The valve must be configured for return temperature increase / decrease or buffer
storage tank partial charging.
Solid fuel boiler pump Q10
For the connection of a solid fuel boiler, a circulating pump for the boiler circuit is
required.
DHW electric immersion heater K6
Using the connected electric immersion heater, the DHW can be heated up
according to operating page "DHW storage tank", operating line "Electric
immersion heater".
The electric immersion heater must be fitted with a safety limit thermostat!
Operating line 5060 of the electric immersion heater's operating mode must be
appropriately set.
Heat request K27
Output K27 is enabled as soon as there is a heat request.
Overtemperature protection K11
Output K11 is enabled when the tempature reaches the set overheat protection
temperature (6209) on the defined reference sensor (OL6208).
It remains enabled until the temperature drops below the overheat protection
temperature by the set switching differential (6210).
