IR Ceiling Fan Remote Control Receiver: recorded scope

IR fan-light receiver listing with recorded F20 reference. Confirm infrared reception, line of sight, wiring and compatibility with the intended remote. This page records what the listing currently states and separates it from what still has to be confirmed for your project. It is a working reference for an enquiry, not a released specification: the approved drawing revision, motor data and test plan take precedence over anything shown here.

What this listing records

Figures taken from a listing title are descriptive. They indicate the intended application; they do not establish the rated conditions of the unit supplied for your programme. Confirm them against the approved project configuration before quoting, sampling or designing around them.

Line-of-sight control constraints

Infrared control depends on a clear optical path to the receiver. Mounting height, lamp diffuser material, ceiling slope and the receiver window all affect whether a command is accepted. The brief should state the intended mounting geometry so that the receiver placement can be evaluated before tooling.

• Receiver window position and its exposure to the room
• Carrier frequency and protocol expected by the handset
• Ambient light conditions at the installation point
• Command repeat and confirmation behaviour at the extremes of range

What to confirm before sampling

These are the inputs the engineering team needs in order to turn this listing into a reviewable specification for fan remotes & controls.

• The receiver or control board this handset must pair with
• Command set, speed steps, timer and light functions in scope
• Radio band, pairing method and operating range in the installed product
• Battery type, button legend and enclosure finish required

Why this page does not quote full specifications

Publishing a numeric table that has not been traced to an approved drawing is worse than publishing none: a buyer can design a housing, a harness or a certification plan around a figure that was never verified. The parameters that decide whether this part fits your product – rated current under your load, thermal margin in your enclosure, connector pinout on your board revision, and the compliance scope for your market – are only meaningful once they are tied to a specific configuration.

What that means in practice is that the review is driven by your inputs rather than by a published table. Send the motor or load data, the available drawings and the target market, and the engineering team can respond with the specific values that apply to your build, together with the measurement conditions behind them. Where a figure cannot be supported for your configuration, the honest answer is to say so and propose the test that would establish it.

Application notes for this listing

Ceiling fan installation

A ceiling fan controller operates in a canopy above the blade set, which constrains both the space available and the radio environment for any remote function. Receiver placement and antenna orientation have to be evaluated with the canopy fitted.

• Space available inside the canopy
• Receiver placement and antenna keep-out
• Behaviour on a momentary power interruption

Handset and receiver as a pair

The handset is only half of the control system. The receiver or board it commands determines which functions can actually be invoked, so the pair has to be specified together rather than sourced separately.

• The receiver or board the handset must command
• Complete function list, including infrequent functions
• Button layout and legend before tooling

A handset is only half of a control system

Remotes are frequently sourced as a replacement part for an existing installation, or as an accessory for a board that is already fixed. In both cases the receiver defines what the handset can actually command. Button layout and legend are easy to compare; the command encoding, the pairing method and the light-function behaviour are where mismatches appear.

• Identify the receiver or board the handset must command
• Confirm whether re-pairing is possible in the field after replacement
• Agree the button legend and enclosure finish before tooling
• Test range with the receiver mounted in its final position

Where this type of part usually goes wrong

Infrared parts fail on geometry more often than on electronics. A receiver that is partially shadowed by the diffuser, or that faces a bright window, will appear unreliable even though the electronics are sound. The mounting arrangement belongs in the specification, not in the installation leaflet.

Validate under the lighting the product will see

Infrared acceptance depends on the optical path and the ambient light. Test with the diffuser fitted, at the mounting height intended for the product, and under both bright daylight and low light. Record the angle at which reception fails, because that angle defines the practical installation envelope.

Keep the receiver window position, the diffuser material, the protocol and carrier settings and the measured acceptance angle together. A change to the diffuser, the window or the receiver orientation should be re-tested, since these are the variables that decide whether commands are received at all.
