Returning power/self-test
The electric boiler is equipped with a time relay, which
blocks part of the immersion heater so that a maximum
of 6.0 kW is connected the first two hours after the boiler
has been disconnected.
The time delay can be easily bypassed by pressing the quick
start button. This action can be used when servicing and
function-testing the boiler.
NOTE
However, there is always 4 minutes between each
step size (see table under heading ”Power control
immersion heater().
EVC 13 has an integrated self-test program. This is activ-
ated by holding the quick start button in, then pressing
the restart button. The quick start button is released when
the relay engages. The self-test runs through the necessary
relay combinations. After completed self-test the electric
boiler must be restarted again.

Power control immersion heater
The boiler temperature is controlled by the outdoor tem-
perature. The control equipment connects power in steps
of 1 – 2 kW and controls itself in the relevant power range.
Restriction of the power is set using the ”Power restriction”
potentiometer, see image. To maintain an even supply
temperature, the stepping is time limited to 3-4 minutes
per power step.

Centralised load control/load monitor
If centralised load control or load monitor is used the HP
pipes for signal cables must be routed to the boiler. The
load monitor is set using the ”Fuse size" potentiometer,
see section "Power control immersion heater" on page 18.
Connection of the load monitor current sensor is made on
the terminal block (14) pre Safety Extra-Low Voltage (SELV),
see image. Centralised load control is connected using
potential free connections on the same terminal block.
