SIMX FAN7194 Heat Transfer Touch Screen Controller

Product Information

The Heat Transfer Touch Screen Controller is a device used to control and monitor heat transfer systems. It features a touchscreen interface and is equipped with Firmware Version 3.4. The controller is designed to accurately sense air temperature in the heat source room and facilitate the efficient transfer of heat to other rooms.

Definitions/Warning/Caution

Before using the product, it is important to understand the following definitions:

WARNING: Refers to conditions where there is a possibility of injury or death if the procedure is not followed.
CAUTION: Indicates the possibility of damage to the equipment, installation, or premises if a procedure is not followed.
NOTE: Provides additional information intended to clarify points, procedures, or instructions.

Warnings:

Please read all instructions carefully before commencing installation.
This appliance is not intended for use by persons (including children) with reduced physical, sensory, or mental capabilities.
If intending to install an air transfer system in a room where gas appliances are used for the heat source, consult the gas fire installation company and refer to Section G4/2.2 (Mechanical Ventilation) of the NZ Building Code for safety criteria.
The system is not designed for use with heat pumps.
Negative pressure from certain models of solid fuel fires can cause smoke from the fireplace to enter the room. Ensure proper ventilation and make-up air supply if using a fireplace that relies on room air for combustion.
Consider using a door vent to circulate air throughout the room.

Caution:

All wiring must comply with national wiring rules.
Any changes or modifications made to the product without prior written approval from the manufacturer will void the warranties.
Take appropriate safety measures when cutting hazardous building materials.

Installation Instructions

To install the Heat Transfer Touch Screen Controller, follow these steps:

Choose an inside wall at eye level in the heat source room, preferably opposite the heat source. Ensure that the air temperature can be accurately sensed and is not affected by direct sunlight or convection currents.
Do not install the controller in wet/damp areas (e.g., laundry or bathrooms), on hot surfaces, in convection currents, or in locations unaffected by changes in room temperature.
Avoid installing the controller near any localised heat source.
Cut an opening in the wall for the flush box and mount it securely.
Run the electrical cable from the roof cavity down to the flush box.
Wire the cable to the power module of the touch screen controller located on the back.
To separate the front screen of the touch screen controller from the back module, carefully insert a flat head screwdriver into the slot and gently lever the screwdriver handle upwards.
Mount the power module to the flush box using the provided screws.

Following these instructions will ensure proper installation and functionality of the Heat Transfer Touch Screen Controller.

Definitions

Before use please read and understand these definitions.

WARNING and/or the use of the symbol refers to conditions where the possibility of injury, or death, exists if the procedure is not followed.

CAUTION

CAUTION indicates the possibility of damage to the equipment, installation or premises if a procedure is not followed.

NOTE

NOTE provides additional information intended to clarify points, procedures or instructions

Warning

Please read all instructions carefully before commencing installation.
This appliance is not intended for use by persons (including children) with reduced physical, sensory or mentalcapabilities, 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.
Precautions must be taken to avoid the backflow of gases into the room from the open flue of gas or other open-fire appliances when mounted in outside walls or soffits.
Isolate the mains supply before making any electrical connections. This system should be installed by a registered electrician.
A means of mains power isolation must be installed in the circuit for the purpose of safe access for any internal cleaning, recalibration or maintenance.
All electrical, electronic and mechanical parts must be installed, and all ducting secured, before applying mains power.
There are no isolated (safety extra low voltage) terminals incorporated. Please treat all terminals as being mains live.

Important

If it is intended to install an air transfer system such as HeatTrans into a room where gas appliances are used for the heat source, the gas fire installation company must be consulted before undertaking installation. Section G4/ 2.2 (Mechanical Ventilation) of the NZ Building Code refers to certain safety criteria which should be considered when installing mechanical ventilation in a room where gas appliances are used. The gas heating installation company can advise on these aspects.
The system is not designed for use with heat pumps.
With certain models of solid fuel fires, negative pressure can cause smoke from the fire place to enter the room where the fireplace is operating.
If you have a fireplace that uses air from the room for combustion, please ensure that make-up air is available to replace the air that is exhausted by the HeatTrans system.
The use of a door vent can assist in circulating the air throughout the room.

Caution

All wiring must comply with national wiring rules.
Any changes or modifications made or attempted to this product, without the prior written approval of the manufacturer, will void any and all stated warranties.
Take appropriate safety measures when cutting hazardous building materials

Installation

Heat Transfer Touch Screen Controller

Install on an inside wall at eye level in the heat source room, preferably opposite the heat source, where the air temperature can be sensed as accurately as possible and not be adversely affected by direct solar radiation or convection currents.
DO NOT install in wet/damp areas (ie. laundry or bathrooms), on hot surfaces, in convection currents, or exposed to direct sunlight or in locations that are not generally affected by changes in the room temperature.
DO NOT install near any localized heat source.
Cut an opening in the wall for flush box and mount it.
Run the electrical cable from the roof cavity down to the flush box.
Wire the cable to the power module of the touchscreen controller, located on the back.
Separate the front screen of the touchscreen controller from the back module. Carefully insert a flathead screwdriver into the slot and gently lever the screwdriver handle upwards.
Mount the power module to the flush box using screws provided.
CAUTION: Using incorrect screws or not tightening screws sufficiently may cause damage to the product when re-assembling.
Ensure the circuit board on the back module is centered so the connectors to the front screen can line up.
CAUTION: Forcing the controller back together without aligning the connectors properly may cause damage.
Carefully attach the front screen to the back power module. Align the top edge, rock in, and listen for a click.
