The two upper lines of the window vary with the load guard’s
measurement method.
Load guard with secondary measurement:
ĮCURRENT LIMIT 1.00A
ĮCURRENT MARGIN 0.10A
Setting values are calculated, for example:
Main fuse:
160 A
Current transformer: 200/5
Boiler, EP 90: 6 kW/stage/8,7 A. See “Technical data”.

ĮMAIN FUSE xxxA
Main fuse: size of the fuse, that must be protected
50 - 63 - 80 - 100 - 125 - 160 - 200A
STEP SIZE xx.xA
The amount of each power stage: defined in the boiler model,
cannot be changed.
ĮMax PWR ( 7) xx.xkW
7-stage boiler
ĮMax PWR (15) xx.xkW
15-stage boiler
Number of stages, power, the boiler will work with. The number
of stages selected is shown in brackets. See stage size in
“Technical information”.
ĮPOWER SPEED STEP...
Quick increase/reduction of power in connection with checks
and acceleration of the delay when it is active. If the delay is
active, the display shows
ĮSPEEDING TIME BLOCK!
Release the button and press it again if you want quick
increase/decrease.
ĮExt PWR LIMIT NO
Stage limit with external signal, 0-100% of selected power,
“Max. POWER”.
NO:
internal limit.
0-5V:
limit with 0-5 V.
0-10V:
limit with 0-10 V or potential-free blocking. This
alternative is selected if the function ”P
ower control
from the heat pump” is used.
4-20mA: limit with 4-20 mA.
ĮExt SET TEMP NO
Temperature setpoint via external signal.
NO: internal setpoint.
0-5V:
nominal value with 0-5 V (0-170°C).
0-10V: nominal value with 0-10 V (0-170°C).
4-20mA: nominal value with 4-20 mA (0-170°C).
ĮCP function NEVER
Operating method for circulation pump supplied with power
by the boiler:
NEVER: no pump operation/pump switched off
AUTO:
The pump starts before power is connected and
stops one minute after all power has stepped out.
If the pump is not in operation, it is run once daily.
In the event of over temperature, the pump starts
and is in operation until the over temperature
situation ends, even if all power is disconnected.
ALWAYS: Pump always in operation.
ECO:
Only with UTK, option.
Pump stop with maintenance operation, when the
outdoor temperature meets the set temperature
according to
ĮECO TEMP, Tout 17°C
in
the Adjustment menu.
