Fan only with water temperature control – allows the user to
select any of the available fan speeds, which will operate only
if the water temperature in the coil is above 32C. This enables
control of the unit via an externally mounted room thermostat
if desired.
l The SLIM-LINE RC can be used on heat pump systems.
l The minimum side clearance is 100mm.
l The maximum ceiling height is 3m.
l Before proceeding with the installation, the heating system
design must be considered and the unit correctly sized to
meet the heat loss requirements of the room at normal fan
speed.
l This unit is supplied with an infra red remote control system
and has 3 operating modes -
l The appliance is not intended for use by persons (including
children) with reduced physical, sensory or mental capabilities,
or lack of experience and knowledge, unless they have been
given supervision or instruction concerning use of the
appliance by a person responsible for their safety.
Children should be supervised to ensure that they do not play
with the appliance.
Automatic – the desired room temperature is programmed in
to the unit and the fan speed is automatically adjusted until
the desired room temperature is achieved.
This unit MUST NOT be installed in a bathroom or other similar high humidity area.
2.0 Heating System Design
This fan convector must be fitted on a two pipe, pumped
circulation heating system.
For optimum fan convector heating performance the system
must be capable of providing sufficient hot water through the
heat exchanger. This means that:
1. The minimum pipe size from boiler to fan convector must be
15mm.
2. This unit is not suitable for use on microbore pipe-work.
4. The system water must be above 32°C for heating mode.
5. For heat pump applications - see Commissioning Procedure
6. This unit is NOT suitable for one-pipe systems.
7. Optimum performance will require effective balancing of
the whole system.
8. This unit must not be used to replace a radiator in an
existing system unless an adequate flow of water through
the unit can be guaranteed.
3. Where the unit is fitted on to a system with other emitters a
separate circuit for the fan convector should be considered
to provide adequate water flow.
3.0 Unit Selection/Sizing
Heat output performance is given in the Technical Data section
of this manual. Outputs are shown for the three fan speeds,
however, it is important to size the unit to match the calculated
heat loss requirements of the room with the unit operating on
the low fan speed. The higher fan speeds are used in automatic
mode when the room temperature is significantly lower than the
preset temperature.
When establishing the temperature difference, ie mean water to
room temperature, allowance should be made for temperature
drop in the system. It is the water temperature of the unit which
dictates the output.
4.0 Location
l This SLIM-LINE RC unit may be fitted to any convenient wall
at a height from floor level that suits the application,
providing an unimpeded flow of warm air into the area to be
heated.
l The minimum distance from the underside of the unit to floor
level is 150mm.
l The unit should be mounted on a flat wall, and stud or
partition walls should be avoided to minimise the possibility
of noise transmission.
2.0
l The SLIM-LINE RC should only be used on closed
circulation, two pipe, pump assisted central heating systems.
3.0
Fan only – allows user selection of any of the 3 available fan
speeds irrespective of room temperature or water
temperature in the coil.
4.0

Displayed Temperature Calibration
l When installation and commissioning are complete, hand over
instruction manual to end-user.
Depending on the location of the unit there may be a difference
between the temperature at the unit and the temperature in the
middle of the room being heated.
Heat Pump and Low Water Temperature Systems
The displayed temperature calibration function enables
calibration in heating mode of the displayed temperature to the
actual room temperature using the following procedure:
In heating mode, the control system brings the fan on when the
water in the coil reaches 32°C. For low water temperature systems,
eg heat pump systems, it is possible to switch off the boost speed
option in automatic mode so that the unit runs in medium or normal
fan speeds depending on demand. This means low outlet air
temperatures from the unit are avoided when the room temperature
is low in relation to the set temperature.
This facility can be switched on or off by following the instructions:
Switch
l Press the ‘On/Off’ key and ‘+’ key for 5 seconds (the display
will flash, alternating between ‘ro’ and the calibration
temperature.
l Calibrate the displayed room temperature by using the
‘+’ and ‘-’ keys with the fan running.

11.0 Operating Instructions
Description
This SLIM-LINE RC unit is fitted with a control system that
provides 3 different operating modes. In automatic mode the
desired temperature set point is selected and the unit will adjust
the fan speed according to the difference between the actual
room temperature and the set point. When the room
temperature reaches the set point the fan will switch off and
thereafter will continue to cycle on and off to maintain the room
temperature. The temperature set point range is 15 - 35°C.
In manual mode, with water temperature control, any of the 3
fan speeds can be selected and the fan will operate when the
water temperature in the coil is greater than 32°C. This means
that heating performance can be controlled manually, and the
unit could be controlled via an external room thermostat.
The unit can be controlled using the infra red remote control
handset supplied with the unit (see fig. 4) and also using
the control panel on the unit (see fig. 5). If necessary, however,
the control panel can be locked electronically to prevent
tampering once the controls have been set (see over).
In manual mode the automatic temperature control is
overridden and any of the three fan speeds can be operated
inrespective of the water temperature in the unit. This means
that air circulation can be provided in summer for example, or
that heating performance can be controlled manually.
