1. Fix unit to wall
Ensure the unit is level and x to the wall using
suitable xings via the chassis mounting holes.
The minimum height from the oor should be
100mm and if there is any shelving above the
unit it should be at a minumum height of 100mm
above the unit.
Installation - product
2. Connect the pipes
We recommend the use of full ow isolating
valves. These valves should be accessible after
completion of the installation. Pipe work can be
brought out from the heater directly or through
the rear chassis.
Connect the heating system ow and return pipes
to the heater pipework. Do not use soldered
ttings to connect onto the heater, as the heat
generated could damage internal components
and prevent disconnection from the system for
maintenance. The pipe nearest the chassis is
the supply ow and the pipe nearest the front
of the heater is the return. Failure to connect
(connections are labelled) to the correct pipes will
result in the heater not working correctly.
3. Electrical supply and electrical
connection
ALL ELECTRICAL INSTALLATIONS CONNECTIONS
MUST COMPLY WITH BS7671, 1992 AND THE
IEE REGULATIONS. CHECK THE VOLTAGE ON THE
HEATER IS CORRECT FOR YOUR SUPPLY. IF IN
DOUBT, CONSULT A QUALIFIED ELECTRICIAN.
If the pre-wired mains cable is damaged, it must
be replaced by the manufacturer, its service agent
or similarly qualied persons.
Isolate the supply and connect the heater
three core mains lead to the fused spur (3A) in
accordance with the instructions provided on
the mains lead label. (The supply wire which
is coloured green or green and yellow must
be connected to the terminal marked E on the
appliance, the supply wire which is coloured black
or blue must be connected to the terminal marked
N on the appliance and the supply wire which is
coloured red or brown must be connected to the
terminal marked L on the appliance).
The fused spur must not be directly above the
heater but should be accessible after completion
of the installation.
1. Introduction
This product is supplied with a wireless battery
powered wall-mounted time and temperature
controller. The product will NOT function without
the wall mounted controller. The controller can
control an unlimited number of heaters.
The controller is primarily designed to minimise
energy wastage and ensure the room is
maintained at the comfort level set by the user.
In the basic setting, the controller is a simple
room thermostat in which the heater will run
until the set temperature is reached. If the room
temperatures falls the heater will switch on again
until the set temperature is reached. The operating
range is between 15°C and 35°C.
1. Choosing a position in a room for the wall
controller. The Controller should be positioned
1.5m above the oor and in the same room
space as the heater. The controller should be
xed to the wall. Avoid areas with draught or
direct sun. Do not position the controller above
or close to the heaters or other heat sources
damp areas or areas where the controller can
be mechanically damaged should also be
avoided. Avoid installing the controller in areas
where there are metal objects between the
heater and the controller. This will reduce the
RF range. The RF range in ideal conditions can
be up to 20m however this can be reduced
when the signal is passing through the walls or
other objects. The range can be also affected
where the controller is mounted close to power
cables, motors or equipment producing strong
electromagnetic eld. If the temperature
control feature is used it is necessary to use one
controller for each room or zone.
2. Installation - The controller is supplied with a
white plastic mounting box that needs to be
xed to a wall at 1.5m above oor level. The
controller is powered by two AAA batteries,
supplied. To activate the controller pull the
plastic tab located at the + battery terminal.
The batteries should be replaced every
12 months.
Check for water leaks. Remove any trapped air
from the system via the vent valve on the top left
hand side of the heat exchanger. Do not over
tighten the air vent.

How it works
Your Ecovector is designed to operate as
part of your central heating system in the same
way as a panel radiator. Providing you leave the
heater switches in their normal operating
positions it will switch on and off automatically
with you central heating system.
Heat from your central heating system passes
through a heat exchanger transferring its heat to
the aluminium ns, room air is drawn in the lower
grille and heated as it passes through the heat
exchanger before being gently expelled back into
the room.
COLD AIR IN
HOT AIR OUT
Ecovector includes a low temperature thermostat
that prevents the fan(s) operating until the central
heating system water passing through the heat
exchanger reaches a set temperature.
How to operate
Ensure your central heating is ON, the controls
calling for heat (Setpoint above the room
temperature) & any fan speed selected; normal
or boost.
Providing your system temperature exceeds 33°C
the fans will run.
