Function input H2 module 1 (7311), Function input H21 module
1 (7321), Function input H2 module 2 (7386), Function input H21
module 2 (7396)
None: no function.
Optg mode changeover HW: Locking of the domestic hot water charging
in case of closed contact at H1/H4/H5/H2.
Optg mode changeover CHs: Operating mode changeover for heating
circuits to protection or reduced operation.
Note
Locking of domestic hot water charging is only possible under the
setting Optg mode change CHs+HW.
Heat generation lock: the heat generator is locked through connecting
terminal H2. All temperature demands for heating circuits and DHW are
ignored. The boiler frost protection function is maintained.
Note
The chimney sweeper function can be applied in spite of the heat
generation lock.
Error/alarm message: Closing the inputs Hx results in a control unit-in­
ternal fault message, which will also be signalled via a relay output pro­
grammed as an alarm output or in the remote management system.
Consumption requirement VK1/VK2: the set flow temperature setpoint is
activated via the connecting terminals (e.g. a ventilation heater function
for door curtain units).
Note
The setpoint must be set under progr. no. 1859/1909/1959.
Release swimpool source htg: Closing the input Hx (e.g. manual switch)
releases the swimming pool heater. Heating is by means of 'heat gener­
ator heating'.
Excess heat draw: an active excess heat discharge enables, for exam­
ple, an external source to force the consumer (heating circuit, DHW stor­
age tank, heating circuit pump) to take up the excess heat.
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/HCs: The operating level can be set via the con­
tact instead of via the internal time switching program (external time
switching program).
Ambient thermostat HCs: 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.
Limit thermostat CH: If the extension module is used for the heating cir­
cuit, an external temperature monitor can be cut in at the inlet (e.g. for
underfloor heating).
Start prevention: With this input a burner start can be prevented.
Consumption requirement VKx 10V: The application 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 H2 module 1 (7312), Contact type H21 module 1
(7322), Contact type H2 module 2 (7387), Contact type H21
module 2 (7397)
With this function, the contact can be set as a resting contact (contact
closed, must be opened for activating the function) or as working contact
(contact opened, must be closed for activating the function).
