General

To get the ultimate benefit from your EVC 13, you should read through these Installation and Maintenance Instructions.

EVC 13 is intended for houses with waterborne heating. The electric boiler must be installed horizontally, ideally on

a cabinet type electric water heater, for example NIBE COMPACT.

The electric boiler is ready for centralised load control, has integrated load monitor and has accessory equipment for

tariff control of the electric water heater, which can be directly supplied direct from the boiler. The controls are con-

veniently located on the front panel and easy to see.

EVC 13 is a high quality electric boiler with a long service life, developed and made in Sweden for Swedish conditions.

Serial number* (103), must always be stated in all correspondence with NIBE.

General

System description

General

EVC 13 has outdoor temperature controlled boiler temper-

ature, which is why a shunt valve is not needed. Outdoor

temperature sensor supplied. The power is connected and

disconnected using two contactors and two relays.

EVC 13 has an integrated circulation pump, expansion

vessel, safety valve, drain valve, load monitoring input for

centralised load control.

Current regulations require the heating installation to be

inspected before it is commissioned. The inspection must

be carried out by a suitably qualified person and should

be documented.

The above applies to electric boilers with a closed expan-

sion vessel. If the boiler or the expansion vessel is replaced,

the installation must be inspected again.

This setting knob is used to increase or decrease the

Select heating curve

The setting depends on the geographical situation

and type of heating system. For correct setting, see

section ・Default setting" on page 7.

Night reduction

This setting knob is used to change the heating for

a certain time of the day. The change is connected

in and out according to the times set on the clock,

see also under "Switch"

Indicator lamps

■The top lamp lights when the immersion heater

is connected.

■The lower lamp is lit:

■When the electrical power is limited because

of overloaded main fuses.

■The first two hours after the boiler is started.

■During activated centralised load control if in-

stalled.

■Alternately flashing lamps mean that the outdoor

sensor is not correctly connected (short circuit or

open circuit).

Clock

The time for connecting and disconnecting of

"Night reduction" is set on the clock, see also under

"Switch"

Fuse

Fuse (2.5 A) for control, and circulation pump.

Night reduction permanently active.

Switch

The power switch has four positions:

■0: The boiler is completely switched off.

■1: Summer mode.

Only the clock and any tariff control for the

heater are operational.

■2: Heating mode.

Normal operating mode, all functions connected.

■3: Emergency mode.

This mode is used in the event of malfunctions.

The boiler/supply temperature is then governed

by the ”Max thermostat”. Circulation pump and

immersion heater are in operation.

The immersion heater is restricted to 6 kW. Any

water heater connected is powered up.

Boiler temperature

The gauge displays the present boiler temperature,

which is the same as the supply temperature.

Boiler pressure

The system/boiler pressure is shown here. The

gauge graduation is 0 – 4 bar. Normal pressure is

0.5 – 1.5 bar.

Heating control system

The indoor temperature depends on several different

factors. During the warmer times of the year, solar radi-

ation and heat given off by people and equipment are

sufficient to keep the house warm. When it gets colder

outside, the heating system must be started. The colder

its gets, the hotter the radiators need to be.

Night reduction

Select heating curve

Heating curve offset

This adjustment is made automatically, however the correct

basic settings must first be made on the boiler (see below).

Default setting

The basic heating is set with the “Heating curve selection”

knob and with the “Offset heating curve” knob. If you do

not know the correct settings use the basic data from the

map opposite. If the required room temperature is not

obtained, post adjustment may be necessary

NOTE

Wait one day between settings so that the temperat-

ures have time to stabilise.

Post-balancing adjustment of the default setting.

Cold weather conditions

If the room temperature is too low, increase the “Heating

curve selection” setting by one step clockwise.

If the room temperature is too high, reduce the “Heating

curve selection” setting by one step anti-clockwise.

Warm weather conditions

If the room temperature is too low, increase the “Offset

heating curve” setting by one step clockwise.

If the room temperature is too high, reduce the “Offset

heating curve” setting by one step anti-clockwise.

Changing the room temperature

Changing the room temperature manually

If you want to temporarily or permanently lower or raise

the indoor temperature relative to the previously set

temperature, turn the “Offset heating curve” knob anti-

clockwise or clockwise. One line approximately represents

a 1 degree change in room temperature.

Changing the room temperature with time controls

Use the "Night reduction" knob to increase or reduce the

room temperature at certain times of day. The start posi-

tion for this knob is 0. A change of one corresponds to

approximately 1 degree change in room temperature. The

change is active during the times that you have set on the

clock (see section“Programming of clock" on page 10).

NOTE

An increase in the room temperature may be ”inhib-

ited” by the radiator or under floor heating thermo-

stats, if so these must be turned up.

Example

The values stated on the map apply for “Heating curve selection”.

The first value applies for low temperature radiator systems. If

you have a high temperature radiator system the stated value

should increase by 3 units. In both cases the “Offset heating

curve” is set to -2.

The value in brackets refers to under floor heating systems. In

this case the “Offset heating curve” is set to -1.

The map values are usually a good starting point and concern

an approximate room temperature of 20°C. The values can be

adjusted later if necessary.

Examples of default values selection

1. Houses with low temperature* radiator systems:

Markaryd = Area 10 (5). Set 10 on the ”Heating curve selec-

tion” knob and -2 on the ”Offset heating curve” knob.

2. Houses with high temperature** radiator systems:

Markaryd = Area 10 (5). Set 10+3=13 on the "Heating curve

selection" knob and -2 on the "Offset heating curve" knob.

3. House with under floor heating***.

Markaryd = Area 10 (5). Set 5 on the "Heating curve selection"

knob and -1 on the "Offset heating curve" knob.

* A low temperature radiator system refers to a system where the supply temperature

needs to be 55 °C on the coldest day..

** A high temperature radiator system refers to a system where the supply temperature

needs to be 70 °C on the coldest day.

*** Under floor heating can be dimensioned very differently. Example 3 above refers

to a system where the supply temperature needs to be approximately 35–40 °C on

the coldest day.
