The formula for calculating the start voltage is:
Vstart = ((10.3 * GP008) - (0.5 * GP007factory)) / GP007current
Vstart
Start voltage.
GP008
The fan speed set with parameter GP008.
GP007factory The fan speed set from factory with parameter GP007.
GP007current The fan speed currently set with parameter GP007.
Blocking input
Caution
Only suitable for potential-free contacts (dry contact).
Important
First remove the bridge if this input is used.
The boiler has a blocking input. A potential-free contact can be connected
to the BL terminals of the connector. If the contact is opened, the boiler will
be blocked.
Change the function of the input using parameter AP001. This parameter
has the following 3 configuration options:
Complete blocking: no frost protection with the outdoor 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 outdoor 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).
Release input
Caution
Only suitable for potential-free contacts (dry contact).
The boiler has a release input. A potential-free contact can be connected
to the RL terminals of the connector.
If the contact is closed during a heat demand, the boiler will be blocked
immediately.
If the contact is closed when there is no heat demand, the contact does
nothing until the main PCB receives a ‘start burner’- command. After that
command, a waiting time starts. If the contact is closed during this
waiting time, the burner does not start and the boiler will be blocked. Set
the waiting time with parameter AP008. A waiting time of 0 will disable
the contact.
