l This unit is supplied with an infra red remote control system
and has 3 operating modes:
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.
Fan only - allows user selection of any of the 3 available
fan speeds irrespective of room temperature or water
temperature in the coil.
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 90°F. This
enables control of the unit via an externally mounted room
thermostat if desired.
4. The system water must be above 90°F for heating mode.
5. Optimum performance of this unit will require effective
balancing of the whole system.
6. This unit should NOT be used to replace a radiator in an
existing system unless an adequate flow of water can be
guaranteed through the unit.
7. The loop must be pumped. HI-LINE fan convectors are not
suitable for gravity circulation systems.
When establishing the temperature difference, i.e. entering
water to room temperature, allowance should be made for
temperature drop in the system. It is the water temperature at
the unit which dictates the output.
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.

/2inch isolating valves are fitted. This
Note: To ensure effective venting of the heat exchanger the flow
pipe should be connected to the bottom connection of the heat
exchanger.
Note: For SLIM-LINE RC installations pipe-work must not be
routed directly underneath the unit as this will adversely affect
the operation of the integral room thermostat. If this cannot be
avoided, the pipe-work must be boxed to prevent heat rise.

Fan Pulse
Fan pulse mode causes room air to be drawn over the air
temperature sensor periodically to maintain room temperatures
more effectively. In certain circumstances, for example when
units are over-sized in relation to the heat loss of the room, it
may be necessary to turn off this function. Use dipswitch 3
according to requirements.
Displayed Temperature Calibration
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.
The displayed temperature calibration function enables
calibration in heating mode of the displayed temperature to the
actual room temperature using the following procedure:
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.
l Press the ‘On/Off’ key to finish.

irrespective 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.
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 90°F. 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).
Heating
The unit will only operate in heating mode when the central
heating boiler is on, the pump is running and the system water
temperature is greater than 90°F. Ensure the boiler is on, and set
timer, boiler controls and room thermostats as necessary.

heat, and the heating system must be correctly designed to
provide adequate flow of hot water to the unit (see Section 2).
If the recommendations in Section 2 are not followed, problems
may arise as detailed below.
Possible Causes
Unit switched off
Temperature set point reached
Unit not switched on at breaker panel
Breaker tripped at panel
Unit isolating valves shut
Water temperature reaching fan
convector below 110°F
(Heater model only)
Low water temperature to unit Turn up boiler thermostat
Poor water flow Vent air from heating system
Turn on
Increase temperature set point
Switch on at breaker
Check all wiring and reset breaker
Open valves
Check boiler -
Programmer ON
Boiler ON and set to high with central
heating pump running
Note: Operation of fan convector can be checked by
switching to manual fan setting
Possible Causes
Boiler thermostat set too low
Lack of flow to fan convector -
Pump set on low setting
Isolating valves not fully open
System incorrectly balanced with unit starved of hot water flow
Pipe sizing to unit too small
Unit incorrectly sized for heat loss of room
with warm water and mild detergent taking care to avoid water
entering the grille areas.
