Värmebaronen EP- 900, -1080, -1200, -1400
Operation
Electric boilers for heating systems or industrial pro-
cesses.
The boiler's power is divided into 30 power stages.
The boilers' control range is 20-95°C.
The output of the boilers can be restricted to one power
stage.
The electric boiler is manufactured in accordance with
Directive 2014/68/EU, Article 4(3).
The electric boiler can be supplied with factory-tted
safety equipment, reviewed by accredited body accord-
ing to EN 12828.
Final examination, under national laws, that the elec-
tric boiler has the necessary safety equipment shall be
carried out by an accredited body when assessing the
monitoring interval for the electric boiler.
The factory-tted safety equipment contains safety
valve(s), high-pressure guard and automatic vent valves.
Double circulation pumps and ow guards are not re-
quired. The boiler can cope with zero ow from a safety
perspective.
A steam-collecting vessel is not required. The safety
valves are tted directly on the boiler's safety pipe.
Safety
The boilers have circuit breakers which are acted on via
shunt release by the boiler's thermal relay, pressure guards
and level protection.
The boilers do not restart automatically after a power cut.
Reliability
The boilers are equipped with leakage current measurement,
which can provide an early indication of possible faults in
the immersion heaters, so that faults can be quickly rectified
without unplanned downtime.
Alarm indication
Alarms are indicated on the boiler's control panel.
Connection for external indication of a buzzer alarm, via
alternating potential-free relay output.
Stainless steel immersion heaters
The immersion heaters are in stainless steel SS2353 with
brass heads.
Pump maintenance operation
Connection for a circulation pump with pump maintenance
operation.
External stage and output control
Connection for external blocking, 0 - 5 V, 0 - 10 V and 4 -20
mA control of power.
External temperature setpoint
Connection for external setpoint in the form of 0 - 5 V, 0 - 10
V and 4 - 20 mA signal.
Output signal for present power and temperature
0 - 10 V signals for the number of power stages connected
and boiler temperature.
Reconnection after power cut
Power is reconnected after a power cut according to recom-
mendation.
Power supply to external unit
Fused 230 V~ output for supply to an external unit.
Aluminium and copper
To facilitate installation, the boilers are fitted with terminals
that make it possible to connect both aluminium and copper
cables. No splicing from aluminium is required.
Cooling fan
The boilers are supplied with cooling fans with air filters.
If the boiler is placed in an environment with an elevated
temperature or dusty environment, additional additions can
be made.
Outdoor temperature compensator - OTC, option
Controls the boiler temperature in relation to the outdoor
temperature via an outdoor sensor.
Series connection for greater power, option
If more power is needed, two boilers can be controlled in
series.
Temperature control in secondary circuit, option
When used with, for example, a heat exchanger, the temper-
ature in the secondary circuit can control the boiler.
