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.
