Introduction

1. This instruction manual describes the commercial fan heater range from Heat store. 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 color 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 trucking 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.

WARNING:
THIS HEATER SHOULD NOT BE INSTALLED WHERE THERE IS A CORROSIVE ATMOSPHERE OR EXCESSIVE DUST.

HSTIRFN wireless controller

The HSTIRFN wireless controller (not supplied with the heater) can control any number of HSCFH heaters within its range. It has a large easy-to-read backlit LCD display and offers up to six temperature settings a day, seven days a week. The HSTIRFN can also provide three levels of heat and 3 fan speeds in manual control mode. Follow HSTIRFN user guide for more details.

HSCFHMC Controller

The HSCFHMC color touch screen controller (not supplied with the heater) giving options for 8 fan and 8 heat settings, together with accurate temperature control, can be mounted up to 50m from the heaters.
The electronic touch screen controller (shown on the picture above) allows the user to control either a single heater or a network of up to 8 heaters with individual settings.
The controller is designed to be mounted on a surface double gang back box, and is powered by an RJ45 connection.
The controller will not fit metal or dry lining back box.
The total cable length of the system can be up to 50 meters.
Up to two environmental sensors HSCHES can be connected to the heaters.

Controllers

Intelligent Fan Control

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.

Selecting heater controls

HSTIRFN Controller

The heater has to be configured for a selected control method at the time of installation. Only 1 control method can be used at the same time. To control heater using the HSTIRFN controller the DIP switch 1 located under the electrical connections cover has to be set to ‘1’ as on the picture below.

Pairing to the HSTIRFN Controller

This must be done, otherwise the heaters will not work.
Power up the HSTIRFN wireless controller (see user instructions for HSTIRFN for details).
Set heater into pairing mode as follows:

Locate the status light.
Turn power to the heater on.
The light should be green. Now, the heater is ready for pairing for the next 20 seconds. After 20 seconds, it will return to normal operating mode and pairing will not be possible.
(Heater must be powered off, and then back on again in this case)
To pair heater with HSTIRFN, Press and hold and buttons together until display shows HSTIRFN identification code.
Press the button. This must be done within 20 seconds from powering up the heater.
The screen on the controller should flash.
If the pairing was successful, the light will show purple for 5 seconds, and the heater will to start. If the HSTIRFN is signalling the heat output to be on, it will begin outputting heat. If the HSTIRFN is signaling the heat output to be off, the heater will switch off after 5 seconds.

Fault detection / indication

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.

Response: Power reduced until heater cools down
2| Temperature measurement fault
Response: Intelligent speed control disabled, fan speed increased
3| Power not detected when heat switched ON
Response: Fan operates as nor- mal
Possible causes: missing phase, blown fuse, faulty electronics
4| Problem with motor
Response: Heater will not work
5| Power detected when not switched ON
Response: Fan runs continuously
6| Internal communication error
Response: Heater will not work

Status indication – main PCB

There are 2 LEDs on the RJ45 connectors indicating that the power is available.
If the heater is in stand-by mode, the green LED is ON. If the heater is switched ON the orange LED is indicating that the auxiliary power is available for the electronic.

Status indication – secondary PCB

For fault diagnostic being carried out by a competent person there is an ad
The red LED will flash one of the sequences as shown in the table below.
The sequence is repeated every 5 seconds.

Secondary PCB

Response: Auto run motor
2| Motor fault
Response: Disable heating
3| Triac heatsink overheat: Response: Reduce heating
4| Low power measurement when triacs switched on:
Causes: Thermal cut-out operated, blown fuse, missing phase

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.

BMS Connection MODBUS Protocol

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 color screen controller must not be used.
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.

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.
