thermostat
The EF12 model is fitted with an adjustable thermostat
allowing the room temperature to be controlled by adjusting
the setting accordingly. The thermostat has a minimum
setting, which can be used as a frost protection setting.
Provided that the controls are set to a heating function, the
heater will come on when the
surrounding temperature falls
to approximately 5˚ C (41˚ F).
Turn the thermostat knob
(Figure 5) to the highest position
to warm the room rapidly. When
the room temperature has
reached the desired level, turn
the thermostat knob back slowly
until the thermostat just clicks off. The heater will then
maintain the room temperature at the chosen level.
Should your heater fail to come on when the thermostat is at
a low setting, this may be due to the room temperature being
higher than the thermostat setting.
60-minute timer
The EF12 model incorporates
a 60 minute delay timer and
thermostat. With the timer set
at ‘0’ the heater will operate at
1kW (on a 240 V supply) or
0.75kW (on a 208 V supply)
and low fan speed under
the control of the thermostat.
With the Timer in operation the heater will output 2kW (on
a 240 V supply) or 1.5kW (on a 208 V supply) and high fan
speed without thermostatic control.
Set the timer by turning the control knob clockwise until the
required operating time is indicated opposite the mark as
shown in Figure 6. The heater will operate at 2kW output (on
240 V supply) or 1.5kW (on 208 V supply) for the set period,
after which the output will reduce to 1 kW (on 240 V supply)
or 0.75kW (on 208 V supply). The timer setting may be
overridden at any time by returning the knob to ‘0’.
protection against overheating
A thermal cutout will switch off the heater if for any reason
it overheats. Should the cutout operate, disconnect heater
from power supply and determine the reason for overheating.
Resolve the reason for overheating before attempting to use
the heater again. To reset the heater it is necessary to switch
off the power to the heater for several minutes.
Faults
If the heater does not give off heat, check the following
points:
• Has the thermostat been set to the desired temperature?
• Has the overheat protection been triggered? See
Protection Against Overheating section.
• Is the fuse in the fuse box switched on?
Mounting Instruction
The heater is supplied with a wall mount bracket, three
1.
(3) screws with wall plugs, and a cable clamp assembly.
Other or supplemental hardware should be used as
needed and as appropriate for the type of wall being
mounted to.
Unlock the wall

bracket and firmly
screw it onto the
wall.
Remove the large
6.
Phillips screw from
back of heater
holding the cable clamp in place (Figure 4). Set screw
and clamp plate aside.
Remove the smaller Phillips screw and larger metal plate

to gain access to the heater’s wiring (Figure 4).
Make the L1 and L2 connections from power supply to the
8.
wires within the heater (wires will be labeled), using the
supplied wire connectors.
Connect ground wire from power supply to Ground Screw
9.
(Figure 4).
Reattach the large metal plate and screw removed in step
10.
2 allowing the cable to feed through.
Run cable over the large plate and clamp in place with the
11.
clamp plate and screw removed in step 1.
Align slots in back of heater with tabs on wall mount
