The electrical connection of this product should be carried out by a competent
electrician and be in accordance with the current IEE wiring regulations.
Only cable with a minimum CSA (cross sectional area) of 2.5mm should be used for
this appliance.
A suitable local isolating switch must be provided in the electrical supply circuit with
at least 3mm clearance on each pole.
WARNING:
Ensure power cable path does not come into contact with internal heater elements or fans. Make
connections as per wiring Diagram (see Fig. 3) and close the grill.

son in accordance with the Building Regulations and the current IEE Wiring Reg-
ulations for electrical equipment. Only heat resistant ordinary polyvinyl chloride
sheathed flexible cord should be used. IE60227 IEC57, rated T90
This heater can either be installed into a suspended or plasterboard ceiling. First it is
necessary to ensure that there is sucient space above the ceiling for the Installa-
tion of this product (see Fig. 1 and Fig. 5).
This product is designed to be suspended by threaded rod or wires/chains. Always
ensure this unit is adequately supported when installed.
Installation in a Ceiling
A hole as indicated in Fig. 1 and Fig. 4 must be cut into the ceiling. Allow an addi-
tional amount for clearance. It may be necessary to fix an internal supporting frame
around the newly cut aperture in a plasterboard ceiling or suspended ceiling
To mount the unit into the ceiling void, use lengths of threaded bar or hooks (not
supplied) screwed into the M8 threaded inserts located in the top side of the heater
(see Fig. 1 for dimensions). Adjust the height of the heater so the inner edge of the
grill surround is flush with the ceiling.

Waking from Standby Mode
When in standby mode, holding ENTER for two seconds will wake the remote and
attempt to reconnect to the product, this will be signified by the connectivity icon
and loading graphic appearing on the screen.
The remote control provides the option of a number of standard control modes,
• Timer Mode: provides the greatest flexibility to the user. Four heating periods are
available throughout each day and these can be customised for every day of the
week. The desired temperature can be set for each time slot independently.
• Manual Mode: Maintains the displayed temperature for an undetermined period.
The default ‘comfort’ temperature in manual mode is set to 21°C however this can
be adjusted to suit.
• Frost Protect: maintains a room temperature of 7°C. This mode should be used to
provide protection against frost.
• Comfort O: no room temperature control
There are also a number of advanced control options and features available
• Runback Mode: This is an additional feature available to manual mode, with this
mode active the manual mode will operate for a determined time period and then
revert to Comfort O mode.
• Setback Mode: This is an additional feature available to timer mode, with this mode
active the appliance will control the room to a pre-set temperature during timer
‘o’ periods.
• Adaptive start Mode: This is a predictive mode that functions alongside the timer
mode. When activated it will automatically calculate when the appliance needs
to switch on so that the desired room temperature has been achieved from the
start of a heat on time period. If not active the appliance will only switch on at the
programmed on time.
• PIN Lock Mode: This mode will lock the appliance in the existing mode and will only
allow some basic functions to operate. Once activated, in order to change settings
the user must input a pre-set PIN. This is ideal where it is desired to limit the use
and functionality of the appliance.
