Introduction
WARNING:
THIS HEATER SHOULD NOT BE
INSTALLED WHERE THERE IS A
CORROSIVE ATMOSPHERE OR
EXCESSIVE DUST.
2.1 Introduction
1. This instruction manual describes the
commercial fan heater range from
Heatstore. These heaters are robustly
designed for use as space heating in large
areas. With a maximum heat throw of up to
11m depending on the room temperature
and selected fan speed, they are ideal for
areas such as garages, workshops and
warehouses.
2. Each heater is equipped with an intelligent
fan control, which allows the heater to
adapt to the environment by automatically
adjusting the fan speed. The heater provides
instant directional warmth, and also has a
fan-only setting for air circulation.
3. The heaters are wall mounted with
multi-directional brackets.
4. Heaters are available in 6kW, 9kW and
12kW rating. The 6kW heater is single phase
and the 9kW and 12kw heaters are 3 phase.
The heaters can be controlled by either
HSTIRFN wireless controller or HSCFHMC
colour touch screen master controller. For
larger areas, up to 8 air curtains can be
easily interconnected using CAT5/CAT6 RJ45
networking cable, when used together with
HSCFHMC controller. The heaters can be
also controlled by BMS using MODBUS
control system.
5. It is recommended that this control cable is
run separately within its own trunking to
avoid external interference.
6. Up to two environmental sensors CHES can
be connected to the heaters when used
together with HSCFHMC controller.
7. Environmental sensors offer 3 functions;
remote temperature measuring, microwave
occupancy sensor and remote or boost
switch connection. All functions are fully
programmable and can be associated with
any heaters in the system.
The controllers aren’t supplied with the
heaters and have to be purchased
separately.

3.1 Automatic speed control
The intelligent fan control incorporates one of the latest low energy consumption EC motors. This
allows the heater to operate quietly, whilst still providing the best possible levels of comfort.
The intelligent fan control is only activated when the heat is switched on. If the heater is running
in fan/boost mode only (heat switched off), then the fan will operate at a fixed speed.
When activated, the intelligent fan control detects the temperature of the room and,
depending on which heat mode is activated, it will calculate the best possible airflow and
adjusts the fan speed accordingly.
In order to maintain a constant airflow temperature, the fan runs at a lower speed when the
ambient temperature is low and will speed up as the room is getting warmer. This will result in
reduced throw at low room temperatures.
NOTE: When turning the heater on, or changing heat mode or fan speed mode, the fan will
respond accordingly after a short time delay.

6.1 Mounting
It is the sole responsibility of the installer to
ensure that the points of attachment to the
building are sound. Consultation with the
consultant/architect or owner of the building
is recommended to ensure that a sound,
mechanically stable installation is achieved.
Before fitting or wiring the heater, ensure that
the casing faces, as shown in figures 1&2,
follow these installation guidance notes.
The wall bracket is secured to one of the inner
cardboard box corners. Cut the plastic bag
to remove it. All fixing screws are attached to
the side of the inner cardboard box.
The heater must always be installed
horizontally, using the mounting bracket
provided. This ensures correct positioning and
adequate clearance.
Assemble the swivel bracket as shown on
Fig.3. Use M8 and M5 bolts with locknuts and
washers as supplied in bag. Attach the
assembled bracket to the bottom of the
heater by using 4 x M6 bolts with plain and
spring washers as shown on Fig.3.
Secure the wall bracket to the wall with
suitable fixings. Ensure the position of this
bracket will allow suitable clearances
between the heater, when fitted, and
adjacent walls. Mini-mum of 3 fixings must be
used to secure the wall bracket to the wall.
Attach the heater to the wall bracket.
Finally, adjust the direction of the heater to
the desired area and tighten up all clamping
nuts and bolts.
Care should be taken when choosing a
position, ideally there should be a clear line of
sight between the heater and controller. If the
signal has to travel around corners, walls or
any metal objects it will decrease the range.
Ensure that the heater is fixed to a secure wall
within the mounting height limits stated in
‘clearance distances’. Mount the heater as
shown in figures 1 and 2.
The angle of the heater can be adjusted in
steps, 22.5 deg. vertically and 180 deg.
horizontally.
The weight of the heaters is
approximately 10kg

9.1 Fault detection
Heaters are equipped with electronic fault
detection. In the event of a fault being
detected, heater will show the nature of the
fault by flashing status LED located at the front
of the heater. The LED will flash one of the
sequences as shown in the table below. The
sequence is repeated every 5 seconds.
9.4 Over heat protection reset
The heater is equipped with electronic over
heat protection and also resettable over
temperature cut-outs. There are two cut-
outs located on the top of the heating
element. In the unlikely event of electronic
failure, the mechanical cut-outs will switch
off power to the heating element. In order
to reset cut-outs, isolate the heater from
power and leave heater to cool down.
The cause of cut-outs operating should be
investigated before resetting as the only
time the mechanical cut-out operates is
when electronics can’t protect heater from
overheating.

1.1 BMS Connection
There are 2 ways for connecting heaters to BMS.
1. Using HSCHES and external switch as a
simple BMS on/off connection
2. Using MODBUS protocol.
The heater is compatible with BMS systems using
MODBUS protocol.
The connection to BMS system can be made using
one of the RJ45 connectors.
Only one means of control can
be used at any time. If BMS is used to control the
heater, the colour screen controller
must not be used.
The BMS can control fan speed and
heat output and also read and report
the heater status.
Speed can be set in the range of 600 -
1700RPM in 1RPM steps. If the speed is
set below 600RMP, the heating element is
automatically disabled. Care has to be taken
when selecting speed. The fan speed should be
always correct for the selected heat output. If the
speed is too low, the heater can overheat.
Heat output can be set in the range of 0 - 100% in
1% steps.
10.2 MODBUS Protocol
The DIP switch 1 must be set to ON position for BMS
control.
The DIP switches 2, 3 and 4 are used to configure
each air curtain with a unique address.
RJ45 cable can be used to network
up to 8 heaters in a daisy-chain
configuration.
