ENV-VST-C - Instruction Manual
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.
Configures button lockout settings for temperature, mode, and fan speed
You can completely block anyone from using the buttons on the front of the unit to change the hold temperature, mode,
or fan speed changes, or restrict them by time. You can also restrict hold temperature changes by range.
• If you configure a time limit, the hold temperature, mode, or fan speed reverts to the original settings after the set
time expires.
• If you configure a range, the hold temperature may not be set higher or lower than the set temperature +/- the range.
Syntax:
LK [MR<State>] [MT<Time>] [FR<State>] [FT<Time>] [TR<State>] [TT<Time>] [RR<Range>]
Variables:
State = An integer value, 0 for disable and 1 for enable.
Time = An integer representing the number of minutes a change is enabled.
Range = An integer representing the number of degrees a temperature is allowed to be changed. Degrees are in the
same scale as set on the thermostat.
MR = Mode Restriction, State=1: disable all changes to Mode. State=0: restrictions to Mode determined by MT (Mode
Time Restriction).
MT = Time Restriction placed on changes to TSTAT Mode
FR = Fan Speed Restriction, State=1: disable all changes to Fan Speed. State=0: restrictions to Fan Speed determined
by FT (Fan Speed Time Restriction).
FT = Time Restriction placed on changes to Fan Speed
TR = Temperature Restriction, State=1: disable all changes to Temperature Heat and Cool Setpoints. State=0:
restrictions to Temperature Heat and Cool Setpoints determined by TT (Temperature Time Restriction), and TR
(Temperature Range Restriction).
TT = Time Restriction placed on changes to Temperature
RR = Range Restriction placed on changes to Temperature
Examples:
SEND_COMMAND 'LK MR1 TR3'
Configures the lockout to completely block changes to Mode and restrict changes to the temperature setting to ±3
degrees.
SEND_COMMAND 'LK TT90 FT90'
Configures the lockout to allow changes to the temperature and fan speed for 90 minutes before reverting to the
original settings.
