Release swi pool solar
This function can be used to enable solar heating of the swimming pool from
externally (e.g. with a manual switch), or to define solar charging priority against the
storage tanks.
Configuration:
Set function Input Hx to Release swimming pool. For details, refer to Charging priority
solar (2065).
Operating level HCs/DHW
The operating level can be set via the contact in place of using the internal time
program (external time program).
Room thermostat HCx
The input can be used to generate a room thermostat request for the selected heating
circuit.
If several inputs Hx are configured for the room thermostat to be used with the same
heating circuit, only input Hx with the highest number is used. The other inputs are not
taken into consideration (no configuration error).
Order of inputs Hx with the same room thermostat configuration:
H7, H6, H5, H4, H3, H2-EM3, H2-EM2, H2-EM1, H1.
DHW flow switch
Here, the flow switch of the instantaneous water heater is connected.
DHW thermostat
Here, the DHW storage tank thermostat is connected.
In addition, DHW sensor (5730) on the Configuration menu is to be set to Thermostat
and no connection is allowed at input B3/B38.
Pulse count
Low-frequency pulses (e.g. for flow measurement) can be acquired by querying the
input.
Feedback flue gas damper
This feedback is required for function Control of flue gas damper (refer to chapter
Control of flue gas damper.
Start prevention
This input allows you to force the boiler not to start by applying start prevention.
Error 193 Start prevention signal input is generated, transferred via LPB, and saved in
the error history.
Start prevention is only applied to the local boiler.
If start prevention is activated at multiple Hx inputs, it will be applied whenever a start
prevention input is active.
Danger!
Start prevention also locks protection functions such as frost protection!
Make sure that the Start prevention function cannot cause any damage.
