consumer the parameter excess temperature discharge can be set to
determine whether the forced signal is taken into account and should
therefore 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 HW: The operating level can be set via the contact in­
stead of via the internal time switching program (external time switching
program)
Room thermostat CH1 up to Room thermostat CH3: With the input a
room thermostat request can be generated for the set heating circuit.
Note
The quick decrease should be switched off for the corresponding
heating circuits.
Hot water thermostat: Connection of the DHW thermostat.
Pulse count: By querying the input the low frequency pulse, e.g. for flow
measurement is recorded.
Checkb sign flue gas damper: Feedback via input H1 in case of activa­
ted flue gas damper control.
Start prevention: With this input a burner start can be prevented.
Consumer request VK1 10V/Consumer request VK2 10V: The applica­
tion node external load x receives a voltage 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 10V: The generator 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).

Contact type H1 (5951) Contact type H4 (5971) and Contact
type H5 (5978)
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).
Voltage value 1 H1 (5953),Voltage value 2 H1 (5955), Function
value 1 H1 (5954) andFunction value 2 H1 (5956)
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".
Frequency value 1 H4 (5973), Function value 1 H4 (5974),
Frequency value 2 H4 (5975) and (5976)Function value 2 H4
F Frequency
W Water flow
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).
