Rotate the dial clockwise until the arrowhead at the right of the dial points to the
current time.
To use the heater in timed mode, it should be permanently connected to the
mains supply. If the power is disconnected, the clock will stop.
To operate the heater in timed mode, the three position switch within the dial
should be in the centre position. If it is in the "I" position, the heater will be
permanently ON. If it is in the "O" position, the heater will be permanently OFF.
USING THE THERMOSTAT
The thermostat can be use to regulate the room temperature.
Turn the heater on, and rotate the temperature control fully clockwise.
The heater will then operate at maximum output. When the desired temperature
is reached, rotate the temperature control anticlockwise until a click is heard. The
heater will then switch on and off to keep the room at the desired temperature.
If the temperature control is rotated fully anticlockwise, it will operate as a "frost-
stat" and switch the heater on if the temperature drops below 4°C, preventing
damage by frost.
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 EH1524 will cost £0.08 per hour to run with the thermostat set to
its maximum.
If the thermostat is used to regulate the temperature the operating costs will be
lower, depending on the room temperature.
