Blocking input
The boiler has a blocking input (Normally Closed contact). This input
relates to the BL terminals of the connector.
If this contact is opened, the boiler will be blocked or locked out.
Change the function of the input with parameter setting AP001. This
parameter has the following 3 configuration options:
Complete blocking: no frost protection with the outside sensor and no
boiler frost protection (pump does not start and burner does not start)
Partial blocking: boiler frost protection (pump starts when the
temperature of the heat exchanger is < 6°C and the burner starts when
the temperature of the heat exchanger is < 3°C)
Lock out: no frost protection with outside sensor and partial boiler frost
protection (pump starts when the temperature of the heat exchanger is <
6°C, the burner does not start when the temperature of the heat
exchanger is < 3°C).
Important
First remove the bridge if this input is used.
Warning
Only suitable for potential-free contacts.
Release input
The boiler has a release input (Normally Open contact). This input relates
to the RL terminals of the connector.
If this contact is closed before there is a heat demand, the boiler will be
blocked after a waiting time. Change the waiting time of the input with
parameter setting AP008.
If this contact is closed during a heat demand, the boiler will be blocked
instantly.
Warning
Only suitable for potential-free contacts.
Connecting the calorifier sensor/thermostat
A calorifier sensor or thermostat can be connected to the Tdhw terminals
of the connector.
