Operation
Switching On the Heater
The controls are located on the right hand side on top of the appliance.
The button marked ‘ ’ controls the electricity supply to the electronic
thermostat. An indicator beside the ‘ ’ button shows when the unit
is powered ‘ON’.
Electrical
WARNING – THIS APPLIANCE MUST BE EARTHED
The electrical installation must be carried out by a competent
electrician, and be in strict accordance with the current I.E.E.
regulations for Electrical Equipment in Buildings.
The wires in this mains lead are coloured in accordance with the
following code:
GREEN AND YELLOW : EARTH
BLUE : NEUTRAL
BROWN : LIVE
BLACK : PILOT WIRE
- see also ‘Pilot Wire Connection’.
The heater is tted with a length of exible cable type H05VV-F size 4
x 1.0mm2 for connection to the xed wiring of the premises through a
suitable connection box positioned adjacent to the heater.
The supply circuit to the heater must incorporate a double pole isolating
switch having a contact separation of at least 3mm.
Pilot Wire Connection
The BLACK control wire is designed to carry a signal from slot in or
wall mounted programmers. If, however a programmer is not being
used, the pilot wire should be isolated in accordance with the current
IEE Wiring Regulations.
IMPORTANT - DO NOT connect the BLACK pilot wire to earth. Care
should be taken with the installation of the pilot wire(s) as when
switching to background (set back) they become energised at 240V
although only at a current of less than 100mA. In every case a suitable
means of isolation must be provided for the pilot wire and marked
to indicate that two sources of supply may be present at the heater.
Where pilot wires are installed separately from the heater nal sub-
circuit they should be protected, double insulated and carry their own
integral earth continuity conductor.
Supplementary Earth Bonding
Should Equipotential Earth Bonding be required the earthing conductor
in the supply cord is deemed to provide the supplementary bonding
connection (see Regulation 544.2.5, 17th Edition I.E.E. Wiring
Regulations).
General
The heater is designed for wall mounting on the wall bracket supplied.
It should only be operated when in the upright position as shown -
see Fig. 1.
All models are splashproof to IPX4 standard and may be used in
bathrooms, however not in the immediate vicinity of baths, showers,
water connections, wash basins or swimming pools.
Before connecting the heater check that the supply voltage is the same
as that stated on the heater.
NOTE - Lit cigarettes, candles and oil burners, combined with the
convection effect of electric heaters can cause soot deposits to build
up on the surface directly above and to the sides of the heater. This
is not a fault of the heater. Extensive burning of candles or smoking
in the operating environment of this product can produce heavy
discolouration within a few months of use.
Wall Mounting
IMPORTANT – The wall bracket supplied with the appliance must
be used. The heater should be positioned observing the minimum
clearances stated around the heater - see Fig. 1 and Fig. 2.
DO NOT locate the heater immediately below a xed socket outlet
or connection box.
1. Remove wall mounting bracket from the back of the heater
by depressing the spring latch at the top of each bracket - see
Fig. 2.
2. Fix the wall bracket securely to the wall through the four screw
holes provided.
3. Present the heater to the wall bracket, and engage lower slots
in the back with bracket.
4. Raise the heater to upright position and push the heater onto
bracket to engage top latch.

Turn on the heater using the ‘ ’ button and rotate the thermostat knob
to the desired position. When the room temperature has reached the
desired level, the power to the elements will be reduced, the heater
will then maintain the room temperature at the chosen level.
NOTE - Should your heater fail to come on when the thermostat knob
is at a low setting, this may be due to the room temperature being
higher than the thermostat setting.
Background Temperature
When used in conjunction with a remote programming device
supporting a background/setback setting, the heater will automatically
operate at a room temperature setting of 50C less than the thermostat
setting when the programme is in background/setback mode.
Limiting the thermostat setting
Before wall mounting the product the installer may wish to limit the
heat selection knob movement for the operator. This may be achieved
by unclipping the knob and removing the two plastic pins (see Fig. 4)
using pliers and inserting them in the preferred holes to limit the knob
movement. Replace the plastic cap.
Setting Desired Temperature (see Fig. 3)
The heater is tted with an adjustable thermostat enabling the room
temperature to be controlled by rotating the knob accordingly. The min
setting ‘ ’ represents a room temperature of approximately 50C and
may be used for protection against frost. The ‘MAX’ setting represents
a room temperature of approximately 300C. The ‘ ’ symbol glows when
the elements are actually heating.

Any 240V insulated cable may be used to link pilot wires around
the ring main. The signal current is low. Suitable connections would
be either an additional single core wire marked or colour coded
appropriately or use a 4 core cable throughout the heater ring.
Operating Instructions
The programmer can be programmed either inserted directly into the
heater or out of the heater. If choosing the latter option, the cassette
must be rst left in the heater for 2 days to charge the battery.
Remember that the battery only lasts for 24 hours.
Operating instructions for the 7-day timer/
programmer module
General
The HSP ELT Electronic panel heater is supplied with a 7-day
programmable controller pre-tted as standard. The 7 Day Timer
programmer offers either individual programming (each individual
heater has a programming
module) or group programming
from a master heater through the
pilot wire. Zone programming can
drive up to 10 slave heaters.
Two heating positions are offered:
comfort and off, with temperatures
set using the controls on the
heater.
For default Screen – see Fig. 5.
Individual radiator programming
Note: When the heater is individually controlled, the black pilot wire
in the mains supply cable should be isolated in accordance with the
current IEE wiring regulations.
Programming a Zone with multiple radiators
Where multiple radiators are installed, the radiator containing the
7-day timer programmer is the Master radiator and is connected
by the black pilot wire to the Slave radiators. The Master radiator
determines the Programme and heating levels for all the radiators
(Comfort and Off), but the actual comfort temperature should still be
set on each individual heater (see ‘Setting Desired Temperature’).
The master heater will switch between Comfort and Off according to
the programme.
Electrical Connection where Master Slave radiators are
installed
DO NOT connect the BLACK (PILOT) SIGNAL WIRE to earth.
When the programmer drives other heaters, connect the pilot wire
from the ‘MASTER’ unit to the pilot wire of a ‘SLAVE’ heater and then
from one ‘SLAVE’ heater to another (in series) – see Fig 6.
Problem Solving
In the event that no display appears on your 7-day timer do the
following: 1. Press any button to reactivate the display.
Failing this – 2. Return to the heater to charge battery (internal battery
lasts for 24 hours when timer is removed from heater). Display will
appear immediately but battery will be fully charged in 2 days.
Mode Selection
There are three different operating modes. Press MODE to cycle
through these:
MAN OFF - heating is
permanently Off – see Fig.
