- Excess heat discharge: an active excess heat discharge enables, for example, an
external source to force the consumer (heating circuit, DHW storage tank, pump
Hx) to take up the excess heat. For each consumer it can be set by the parameter
excess temperature discharge whether the forced signal is paid attention to and
therefore should take part in the heat discharge or not.
- Release swi pool solar: This function enables the solar swimming pool heater to
be released externally (e.g. via a manual switch or the solar charging priority to
be specified as compared to the storage.
- Operating level DHW/HC's: The operating level can be set via the contact instead
of via the internal time switching program (external time switching program)
- Room thermostat HC's: With the input a room thermostat request can be gener-
ated for the set heating circuit.
Note: The quick decrease should be switched off for the corresponding heating cir-
cuits.
- DHW thermostat: Connection of the DHW thermostat.
- Pulse count: By querying the input the low frequency pulse, e.g. for flow meas-
urement is recorded.
- Feedback flue gas damper: Feedback via input H1 in case of activated flue gas
damper control.
- Start prevention: With this input a burner start can be prevented.
- Consumer request VKx 10V: The application nodes external load x receives a volt-
age signal (DC 0-10 V) as heat request. The linear curve is defined via two fix
points (voltage value 1/function value 1 and voltage value 2/function value 2
(only applies to H1).
- Preselected output: The source receives a voltage signal (DC 0 - 10 V) as output
request. The linear curve is defined via two fix points (voltage value 1/function
value 1 and voltage value 2 / function value 2 (only applies to H1).
- Flow measurement: Here a flow sensor can be connected which indicates the
flow volume via a frequency (only applies to H4).
With this function, the contacts can be set as resting contact (contact closed,
must be opened for activating the function) or as working contact (contact
opened, must be closed for activating the function).
The linear sensor curve is defined over two fixed points. The setting is made with
two parameter pairs for Function value and Voltage value (F1 / U1 and F2 / U2).
The function value is specified to a factor of 10, i.e. if you require 100 °C, you
should select "1000".
The linear sensor curve is defined over two fixed points. The setting is done with
two parameter pairs for function value and frequency value (F1 / U1 and F2 / U2).
