Assembly instructions | LK Electric Boiler 11-n
The boiler's output can be altered by using the 0 –
10V DC signal, which corresponds to 0%–100% of
the boilers capacity as installed: see below. Con-
nection is implemented to the base of the circuit
board. The jumper between brackets 2 - 3 is not
involved in this function.
Installed capacity
The selected number of levels corresponds to the
installed capacity.
Example:
The selection has been done so that the boiler's
maximum allowed output is 7.9 kW, five levels
selected. Installed capacity corresponds to 7.9
kW. When applying voltage-based control, 0 –
10V DC, 10V is needed for connecting five levels.
The same applies to the voltage signal for con-
nected capacity.
Delay in connection following a voltage non-
response
In accordance with the regulations, the electric
heating capacity in excess of 6 kW is delayed fol-
lowing reconnection after a voltage non-respon-
ses of more than three minutes.
Once the voltage is back on, no more than three
output levels are connected; the remaining levels
are delayed by approx. 2 hours.
13
The connection delays can be temporarily by-
passed in order to monitor the functioning of the
boiler. Press down and keep pressed down the
SNABB (Quick) button, no. 13, until the illumina-
ted text "Status" is shown.
