1.1 GENERAL
The Grant Solo range consists of two wall-mounted fan
convectors, the Grant Solo Compact and Grant Solo
CompactMAX, and the Grant Solo Hideaway model designed to t
under kitchen units or in other similar locations.
For heating capacity details on all three models refer to Section 2
of these Instructions.
Grant Solo fan convectors are supplied with a simple electronic
control panel. Refer to Section 10 for further details and operating
instructions. Each fan convector is individually controlled to
provide a exible and responsive means of heating each space.
They are designed to be integrated into low temperature heating
systems using air source heat pumps, condensing oil, gas and
biomass boilers, etc.
Each Solo fan convector requires a 3A fused 230V 1ph 50Hz
electrical supply. Refer to Section 5 for further details.
A double pole mains ON/OFF switch is factory tted to all Grant
Solo units.
On the Solo Compact and CompactMAX models this is located
under the right-hand end of the front casing. On the Solo
Hideaway model this switch is located on the right-hand side of
the unit.
The steel chassis of the Solo Compact and Solo CompactMAX is
xed directly to the wall. No wall mounting brackets are required,
keeping the unit as close to the wall as possible.
With the Solo Hideaway unit, the steel chassis is xed directly to
the plinth or similar when tting under kitchen units or other xed
units.

1.2 OPERATING PRINCIPLES
The Grant Solo range of fan convectors use backward curved
impellers and they are designed to ensure zero convection and
therefore minimal heat emission when the fan is not running. This
eliminates the need for any radiator control valves.
The heat exchanger does not touch the outer case but is insulated
from it, providing a low casing surface temperature regardless of
the water ow temperature. The top grille prevents contact with
the heat exchanger.
With the electrical supply to the Solo fan convector switched
on; when the water temperature sensor (located in the heat
exchanger) detects that the water temperature entering the unit
exceeds 29°C the unit will start.
The air temperature is then sampled over a 60 second period by
the air temperature sensor located at the rear of the unit.
The user can then set the required room air temperature between
18 to 24°C via the control panel on the front of the unit. Refer to
Section 10 - Operating Instructions for further details on setting
the required air temperature.
The Grant Solo microprocessor control system predicts the air
temperature at occupant level as low-level temperatures are
always colder than at occupant level and would provide incorrect
data on which to determine the level of heat output required.
If the difference between the sampled air temperature and the air
temperature setting on the unit is greater than 1°C the heat output
of the unit is increased with the fan running on the ‘High’ setting.
When the air temperature rises and the difference between the
sampled air temperature and the air temperature setting on the
unit is less than 1°C the heat output is decreased with the fan
running on the ‘Low’ setting.
When the air temperature reaches the setpoint, the unit is
switched off and enters a ‘sleep’ period for 8 minutes. After this
the air temperature is then sampled over a 60 second period.
If there is no change and no heat output is required, the unit
enters an 8 minute ‘sleep’ period again before sampling the
air temperature for 60 seconds again, until a difference exists
between the sampled air temperature and the air temperature
setting on the unit.
The Grant Solo unit will then repeat the start-up sequence again.

BOOST FUNCTION
The boost function is activated by pressing the Boost button
on the control panel fascia. Refer to Section 10 - Operating
Instructions.
The boost function overrides the normal temperature control and
runs the fan at higher ‘Boost’ level for a period of 20 minutes to
provide a greater heat output than the normal operation.
After this period has elapsed the Solo unit automatically returns
to the normal temperature control with the fan operating at either
‘Low’ or ‘High’ setting as dictated by the difference between the air
temperature and the air temperature setting on the unit.
