GENERAL SAFETY REQUIREMENTS
Domestic wiring must be tested periodically by a qualified electrician at least
once every 10 years or at every change of occupancy.
For office and retail premises, and buildings such as village halls, the wiring must
be inspected at least once every 5 years.
It is recommended that all buildings be fitted with smoke alarms (it is mandatory
for new buildings)
OPERATING COSTS
At time of going to press, the average cost of electricity is £0.13 per unit (kilowatt-
hour). The amount you are being charged will be shown on your electricity bill.
At this cost, the running costs will be as follows:
EH1550 £0.07 per hour
EH1552 £0.13 per hour
EH1554 £0.21 per hour

These figures apply with the temperature programmed to its highest setting.
The running costs will be lower if programmed to a lower temperature, or if the
ambient temperature is higher.
OPERATION
Plug the mains lead into a 13 Amp mains socket.
If connecting via an extension lead, make sure that the lead is rated at 13 Amps,
and that it is fully unwound.
Switch the unit on at the mains socket, and at the switch on the side of the
heater. The display will flash briefly, then will show the current room temperature,
and the operating mode. There are six operating modes:
,
-1,
-2, ,
and
P
.
The modes are as follows:
= comfort mode.
-1
= 1°C below comfort mode temperature
-2
= 2°C below comfort mode temperature
= economy mode (3½°C below comfort mode temperature)
= frost protection mode (keeps the temperature above 7°C)
P
= program mode – the heater is controlled by a 7-day programmable timer,
which can be programmed as detailed below.
To change mode press MODE repeatedly until the symbol for the required mode
is displayed.
