AMX ENV-VST-C manual Displays the current forecast, Temperature scale, Dew Point 55F, Variable

Programming

AxLink Commands (Cont.)

CF	Displays the current forecast.
	Syntax:
	CF F<Temp> W<Direct> S<Speed> H<HRead> D<DewPT>
	Variables:
	Temp = The wind chill or heat index that denotes what the temperature feels like outside. The
	temperature is reported in the same scale as set on the thermostat: Fahrenheit (F) or Celsius (C).
	Direct = A single character noting the wind direction (N, S, E, or W).
	Speed = The wind speed in either miles per hour (mph) or kilometers per hour (kph), depending on the
	temperature scale.
	HRead = The current percent humidity reading with a range of 0 to 100%.
	DewPT = The current dew point temperature reported in the same scale as set on the thermostat: F or
	C.
	Example:
	SEND_COMMAND ’CF F40 WN S25 H35 D55’
	Reports the forecast as Wind Chill: 40F, Wind Direction: North, Wind Speed: 25 mph, Humidity: 35%,
	Dew Point: 55F.
?EXTERNAL_	Queries for the temperature measured by the external sensor. If the external temperature sensor is set
TEMP	to Off, the response reports OFF.
	Syntax:
	?EXTERNAL_TEMP
	Example:
	SEND_COMMAND ’?EXTERNAL_TEMP’
FILTER	Set the number of days for a filter reminder.
	Syntax:
	FILTER <days>
	Variable:
	days = The number of days until the filter change reminder activates. The range is from 0 to 180.
	Example:
	SEND_COMMAND ’FILTER 30’
?FILTER	Queries the number of days before the filter reminder turns on.
	Syntax:
	?FILTER
	Example:
	SEND_COMMAND ’?FILTER’
FM	Sets or changes the thermostat’s scale, date, or time format.
	Syntax:
	FM [S<TSCL>] [D<DFMT>] [T<TFMT>]
	Variable:
	TSCL = A single character: F for Fahrenheit or C for Celsius
	DFMT = A single character: D for DD/MM/YYYY, M for MM/DD/YYYY, or
	Y for YYYY/MM/DD
	TFMT = A single character: 1 for 12-hour or 2 for 24-hour clock.
	Example:
	SEND_COMMAND ’FM SF’
	Sets the thermostat scale to Fahrenheit.
	SEND_COMMAND ’FM DD T2’
	Sets the date format to DD/MM/YYYY and the time format to 24-hour clock.
