General
ROOM SENSOR RG 0 is used together with NIBE FIGHTER
300/400, FIGHTER 30/40, FIGHTER 30P/360P/40P,
FIGHTER 20/220/330 as well as with NIBE EVC 3,
EVC 240 and EVP 230. The room sensor can correct the
temperature to radiators or floor loops depending on the
increased indoor temperature in connection with solar
incident radiation, heating from another heat source or
increased indoor activity. The room sensor can also quickly
correct the temperature in connection with the reconnec-
tion of disconnected power output, for example, centrali-
sed load control. The room sensor must be positioned with
care to work correctly, see the Installation section.
Mounting & Installation
It is important that the room sensor is not disturbed by any
other heat source, for example, lamps, TV or other warm
objects. Curtains should not block the sensor.
Install in a neutral position where the set temperature
is required. A suitable place is on a free inner wall in a
hall approx. .5 m above the floor. However, the sensor
must not be prevented from measuring the correct indoor
temperature, for example, by placing in a niche, between
shelves, behind a curtain, above or close to a heat source
or the like. Also consider any draughts from exterior doors.
Neither must the unit be affected by solar incident radia-
tion.
The conduit should be sealed next to the sensor to prevent
a draught in the pipe, which could affect the sensor.
The room sensor is connected according to the installation
instructions of the product.

Setting
This room sensor measures the temperature in homes and
regulates the heat to the heating system.
If there are thermostat valves on the radiators in the same
room as the room sensor these should be fully open in
order for the room sensor to work correctly.
However, radiator valves in areas such as bedrooms, where
a slightly lower temperature is required, should be set to
the required temperature.
The required temperature can be set using the knob on
the room sensor unit. The scale is graduated  – 9, where
5 equals approximately 2 °C (house type relevant setting
of curve slope and parallel displacement). Reading the set
temperature can be done on the display screen on the ap-
paratus. However, EVC 3 does not offer this possibility.
The maximum room temperature setting is 30 °C and the
lowest setting is approximately 5 °C.*
If the room temperature changes the room sensor senses
this and compensates the flow temperature to the radia-
tors to maintain the required temperature in the room. The
reason for the lower temperature can be intensive airing or
disconnection of the power during specific periods of the
year, i.e. centralised load control. Centralised load control
is designed to save and redistribute electrical power during
periods when power consumption is high and means that
the immersion heaters in heating installations do not get
the necessary power to maintain a specific room tempera-
ture. Under normal conditions the room temperature does
not change that much.

Mechanical design

Room temperature sensor RG 0 is intended for wall
mounting. Installation can either be surface mounted or
using recessed connection boxes. The connection cable
can be either recessed or surface mounted. It should be a
screened three wire cable, where the screen is connected
to the signal ground.
The enclosure is manufactured of plastic and consists of a
bottom section with terminal blocks and components for
setting and measuring the room temperature and a knob
to set the required temperature.
The temperature sensing element is made up of an NTC-
resistor.
