# Decoder for Honeywell fan remotes.
|
|
#
|
|
# This fan is made by Intertek (model 4003229) but is sold by Honeywell
|
|
# as a model 'Salermo', number 10285. This fan may be sold under different
|
|
# makes and models, YMMV.
|
|
#
|
|
# Honeywell fans use OOK_PULSE_PPM encoding.
|
|
# The packet starts with a 300 uS start pulse.
|
|
# - 0 is defined as a 300 uS gap followed by a 900 uS pulse.
|
|
# - 1 is defined as a 900 uS gap followed by a 300 uS pulse.
|
|
#
|
|
# Transmissions consist of a short start bit followed by bursts of 24 bits.
|
|
# These packets are repeated up to 23 times.
|
|
#
|
|
# Possible packet layout:
|
|
#
|
|
# Bit number 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23
|
|
# -----------------------------------------------------------------------
|
|
# Value 0 0 0 1 0 1 1 0 1 1 0 0 1 1 0 1 |Value| Cmd | 1 !d d
|
|
#
|
|
# It is pure supposition that the leading 0x16CD and bit 21 are fixed values.
|
|
# I do not have more than 1 remote to test and there's no mention in the manual about
|
|
# dip switch settings, nor are there any on the remote. It's also possible that the
|
|
# value occupies 3 bits and the command is only two bits. It's also possible that
|
|
# there's no such command/value distinction. It looks very suspicious that the fan
|
|
# speed commands all share command 000 and the speed value (bit-reversed) appears in the
|
|
# value area.
|
|
#
|
|
# Button Fixed Other Bits Function
|
|
# ONE 16CD 1 0 0 0 0 1 !d d Low speed fan
|
|
# TWO 16CD 0 1 0 0 0 1 !d d Medium speed fan
|
|
# THREE 16CD 1 1 0 0 0 1 !d d High speed fan
|
|
# OFF-M 16CD 0 0 0 1 0 1 !d d Fan off (momentary press)
|
|
# OFF-C 16CD 0 0 1 0 1 1 !d d Light off delay (continuous press)
|
|
# STAR-M 16CD 1 1 0 1 0 1 !d d Light on/off (momentary press)
|
|
# STAR-C 16CD 0 1 1 1 0 1 !d d Light dim/brighten (continuous press)
|
|
# ONE+THREE-C 16CD 1 0 1 0 1 1 !d d Learn mode ONE+THREE (continuous press)
|
|
#
|
|
# The 'd' bit indicates whether the D/CFL button in the battery compartment
|
|
# is set to 'D' (1 bit) or 'CFL' (0 bit). This switch inhibits the dim
|
|
# function when set to CFL. The !d bit seems to just be the complement of 'd'.
|
|
#
|
|
# Since the COMMAND/VALUE paradigm is not verified and only seems to apply to the fan speed
|
|
# buttons, we'll decode using the full 3rd byte right-shifted by 3 bits to omit the fixed '1'
|
|
# and 'Dim' bits.
|
|
#
|
|
# byte[2] >> 3:
|
|
# -------------
|
|
# 0x10: Low fan speed
|
|
# 0x08: Medium fan speed
|
|
# 0x18: High fan speed
|
|
# 0x02: Fan off, momentary press of the power button
|
|
# 0x05: Delayed light off, extended press of the power button
|
|
# 0x1A: Light on/off, momentary press of the 'star' button
|
|
# 0x0E: Light dim/brighten, extended press of the 'star' button
|
|
# 0x15: 'Learn' mode - hold ONE+THREE (low+high) for 5+ secs. Pairs remote to fan.
