Controlling HN Heaters

As HN shortwave infrared halogen heaters are 100% effective the instant they are switched on, we recommend a control system that
will de-energise a heater when heating is not required. This can be achieved by means of a Push Button Timer or a Movement detector.

Push Button Timer – TS-3 pre-programmed time delay

The BN Thermic TS-3 is a compact, surface mount, weatherproof device conforming to IP66. A simple push button will energise a heater or heaters for a pre-programmed period between 2 minutes and 2 hours. Once this period has elapsed the heating will be automatically switched off until the button is pushed again. The device is vandal resistant and tamperproof meaning only authorised personnel can adjust the time settings. For full details of the TS-3 click here.

The TS-3 has a switching capacity of 16A. It can therefore directly switch a combined load of up to 3kW. Larger loads or 3-phase loads
can be switched via a suitably rated contactor.

Push Button Timer – TS-4 user selectable time delay

The BN Thermic TS-4 is designed for installation into a standard single-gang back box. A simple push button provides 15 minute/ 30 minute / 1 hour / 2 hour settings. Once the selected period has elapsed the heating will be automatically switched off until the button is pushed again. The time setting can be changed at any point during the cycle and the timer also provides a means of switching the heating off. For full details of the TS-4 click here.

The TS-4 has a switching capacity of 13A. It can therefore directly switch a combined load of up to 3kW. Larger loads or 3-phase loads can be switched via a suitably rated contactor.

Movement Sensor

The BN Thermic WH-402 is a compact, surface mount, weatherproof device conforming to IP55. The WH-402 will detect movement in an area up to 12m from its mounting position in a 180° arc. Both distance and angle of detection can be reduced if required. Once movement has been detected, the heating will be switched on. If no further movement is detected within a pre-programmed time period (5 seconds to 18 minutes) the heating will be automatically switched off.

The device is vandal resistant and tamperproof meaning only authorised personnel can adjust the time settings. For full details of the WH-402 click here.

The WH-402 has a switching capacity of 16A. It can therefore directly switch a combined load of up to 3kW. Larger loads or 3-phase loads can be switched via a suitably rated contactor.

Dimmer

In specific applications there may be a need to adjust the intensity of the heat output from a Shortwave Infrared Halogen Heater. The BN Thermic VR-1 provides adjustment between 0% and 100% of heater output. It also has a definite ‘click’ to off allowing it to be used as an on/off switch. For full details of the VR-1 click here.

The VR-1 has a switching capacity of 13A. It can therefore directly switch a combined load of up to 3kW. For larger loads more than one VR-1 dimmer will be required.

Heater Selection

Heat Requirements

Use Table 1 to determine the total kW output required. The W/m² applicable to the type of activity and the nature of the building should be multiplied by the total area in m². The ‘spot heating’ figure should be used when heating a section of an otherwise unheated building.

The output, position and mounting height of the heaters can be determined using
Table 2. We suggest that the areas covered by individual heaters are allowed to overlap by 10% to 15% to ensure even coverage.

Table 1
W/m² required
	Heavy Work	Light Work	Spot Heating
Highly insulated	150	200	250
Insulated	175	225	250
Un-insulated	200	250	275
Lightcladding	250	300	300
Badly insulated/damp	300	300	300

Spot Heating

As an additional guide to spot heating, we would also recommend heating from two directions, to cover the area from opposite sides. This will ensure an overall feeling of comfort and warmth. A heat loading of 250 - 300 W/m² can be cosidered as a guide for this type of area.
