HOW TO CONNECT UP A HEAT TRANSFER SYSTEM WITH A WEISS ER12B DIGITAL CONTROLLER
1. The active line in is connected to terminal 1 at the rear of the control unit.
2. The active line out to the inline fan unit is connected to terminal 3 at the rear of the control unit.
3. Neutral connections are common to terminal 5 at the rear of the control unit.
4. The thermostat is then set to the temperature that is required to be maintained in the room with the main heat
source (the room with the thermostat) using the up and down arrows to modify the smaller number (top right of
display).
DIGITAL CONTROLLER
The enclosed Weiss Heat Transfer System comes complete with a wall-mount controller. Weiss Heat Transfer Systems MUST
ALWAYS be wired through the included controller. The best placement is in a convenient location within the room with the
heat source, around light switch height, this can vary depending on room layout –but use this as a guide. The controller
needs to be fitted in accordance with the instructions enclosed with the controller unit. Ensure the controller is located in the
same room as the heat source, approximately 3-4 metres away at wall switch height.
Do NOT test this product, or an installation that includes this
product with a Mega as it will damage the thermal protector.

FITTING INSTRUCTIONS
Thank you for purchasing this quality Heat Transfer System product by Weiss™.
With a Weiss™ Heat Transfer System selected rooms can be warmed by transferring heat from an area with a slow
combustion fire as the main heat source. Not designed for use with a heat pump.
PLEASE READ ALL INSTRUCTIONS CAREFULLY BEFORE COMMENCING INSTALLATION.
Note: Pictures and diagrams on packaging are designed only to be used as a concept. All installation details should be
carried out as per the instructions herein.
Note:THIS PRODUCT MUST BE INSTALLED BY A REGISTERED ELECTRICIAN
Heat Transfer System can be installed into any rooms that require warmth to ward off winter chills. The subtle design and
whisper quiet operation makes the unit suitable for hallways, bedrooms and other family areas.
SUITABILITY
Heat Transfer System (includes Ducting, thermostat and inline fan) has been designed for ceiling cavity installation.
BEFORE YOU START
Heat Transfer System must not be mounted in areas subject to direct splashing. Refer to New Zealand standard NZECP2: 1988
Section 4.6 and Australian Standard AS3000:1991, Section 6.2.
Extractor fans mounted at high levels (ceiling installation) are required to be installed so that the fan blades are more than
2.3m above the floor.
DUCTING
All ducting components that are required to duct your Heat Transfer System are included in this unit. A total ducting length
of 12 metres is included with this unit. (4 x 3 metre lengths).
SAFETY NOTE
This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or
lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance
by a person responsible for their safety. Children should be supervised to ensure that they do not play with the appliance.
As this appliance does not have a plug included with the supply cord, appropriate means of disconnection are required to
be incorporated in the fixed wiring in accordance with the AS/NZS wiring rules. . Precautions must be taken to avoid the
back-flow of gases into the room from the open flue of gas or other fuel-burning appliances. Ensure that the fan is switched
off from the supply mains before removing the guard.
Weiss recommends you always operate this product with a thermostat and do not leave running over night.
IMPORTANT
Decide on which rooms you want to warm, and check the distances between these rooms (in a straight line) to check your
overall ducting requirement.
The Weiss Heat Transfer Systems are not heat generating systems. The systems have been designed to transfer heat. To
ensure that minimal heat is lost while being transferred from one room to another, the ducting included is fully insulated.
Be sure that you have sufficient surplus heat available to be transferred to additional rooms.
Fit all duct work and secure the fan unit prior to the connection of the electrical supply.
FOR OPTIMUM PERFORMANCE
A well insulated house with a ceiling height of 2.4 meters will be the most effective with a Weiss Heat Transfer System. You
may have to run your Heat Source at a higher setting to be able to transfer the extra heat created to other rooms. When
starting the system, set the thermostat to the temperature that is required to be maintained in the room with the main heat
source (the room with the thermostat). This means that surplus heat will then be moved through the transfer system to other
parts of the house. In a typical installation, it will take approximately one hour to warm rooms with transferred heat

1. When mounting the inlet vent make sure it’s far enough from the flue to avoid excess heat on the fascia and will not
ingest too much smoke when the firebox is opened, (Between one and two meters from the flue.) The fascia mounting
body must fit freely in the hole
2. Finally, attach the ducting to the rear of the fascia body, secure with provided cable tie, repeat step for outlet vents.
**SEE PLACEMENT OF OUTLETS
3. Slide the outlet vent fascia mounting back into place and screw into place using the four 6x¾ pan head screws
provided. Press the fascia ring onto the body and then screw the centre diffuser into position
4. In the ceiling cavity suspend the motor junction from the rafters. When fitting the ducting, ensure that the arrows on the
motor housing are pointing in the direction of the outlet vent.
There is a directional arrow on the main fan body showing the flow of air through the inline fan unit.
FINAL STEPS
Finally, connect the wiring as illustrated in the wiring diagram above.
Note: Approximate means of disconnection are required to be incorporated in the fixed wiring. This product must be
installed by registered Electrician.
CLEANING AND MAINTANANCE
To clean the fascia, simply wash it by hand with a damp cloth and warm soapy water. Do not use abrasives or solvent
cleaners. The fan unit needs to be wiped clean internally every 2 years to remove dust and residue from the fan blades and
motors and the terminal connections also need to be checked and tightened at this time.
All this maintenance work must be undertaken by a registered Electrician.
Isolate the unit from the mains before cleaning.
LENGTH OF DUCT
Have the Heat Transfer System fan junction-to-room lengths as short as possible,
2 lengths (6mtrs) of ducting must be fitted between the inlet grill and the Fan motor junction. if necessary an extra long inlet
can be boosted by an inline fan (Weiss FV05CP) wired back to the main fan terminals. Have the duct stretched out and as
straight as possible. Be sure to cut off any excess. Support duct and bends from the rafters as necessary.
**PLACEMENT OF OUTLETS
Keep the outlet ducting lengths as short as possible - this increases efficiency. It is not necessary, to put outlet in the centre
of the room. The outlet vent needs only to be in the corner of the room.
Note: It takes a while to heat a room and is dependent on humidity and on the moisture content of the furnishings. For
warm air to flow the system must be “open” i.e., doors open back to the inlet. The fire or heat source needs to be turned
full up. Air the house occasionally in fine weather. High studs, or badly insulated homes will remain more difficult to heat
than low ceiling –well insulated homes.
OPTIONAL ACCESSORIES
This product has been designed to operate most efficiently with up to 15 meters of ducting.
If you require longer ducting, we recommend that you install the Weiss™ Inline fan unit (Cat No FV05CP) along with a
Weiss™ Insulated Ducting length – with joiner (Cat No FV63)
The optional Inline fan motor is best placed on the inlet side of the main fan.
QUESTIONS AND ANSWERS
Q: Will the air from the outlet feel hot?
A: It will depend on the available heat from the heat source. An outlet temperature of about 20ºC to 25ºC is common, but
this will not feel warm to your hand. Average skin temperature of your hand is 28-32ºC.
Q: Do I use the controller supplied.
A: A controller MUST always be used.
Q: My house has a high stud / is badly insulated, will this product still work?
A: Yes, but obviously not as well as in a well insulated low-stud home. It will always take longer to warm a large volume
