ENV-VST-C - Instruction Manual
Sets or changes the thermostat's mode. Supported thermostat modes include Program, Vacation, or Hold Temperature.
• Vacation mode includes the heat, cool, humidify, and dehumidify setpoints to maintain, and the duration of the
Vacation mode in days and hours.
• Hold Temperature mode includes the specified heat and cool setpoints to maintain.
Temperatures in the message are in the same temperature scale as set on the thermostat: F or C.
Syntax:
MD M<Mode> [H<HSP> C<CSP> U<HUSP> D<DUSP> Y<Days> R<Hours>]
Variables:
Mode = P, V, H, or PH for Program, Vacation, Hold, or Permanent Hold. If you are setting Hold mode, you must
establish settings for HSP and CSP. If you are setting Vacation mode, you must establish settings for all variables.
HSP = The heat setpoint to maintain in degrees in the scale set on the thermostat.
CSP = The cool setpoint to maintain in degrees in the scale set on the thermostat.
HUSP = The humidify setpoint to maintain in % RH.
DUSP = The dehumidify setpoint to maintain in % RH.
Days = The number of days to maintain Vacation mode.
Hours = The number of hours to maintain Vacation mode.
Examples:
SEND_COMMAND 'MD MP'
Sets the mode to Program.
SEND_COMMAND 'MD MV H60 C85 U40 D65 Y3 R6'
Sets the mode to Vacation with settings of heat setpoint: 60F, cool setpoint: 85F, humidify setpoint: 40%, and
dehumidify setpoint: 65% for 3 days and 6 hours. The thermostat calculates the end time by retrieving the current time
and adding the days and hours from the command to it.
SEND_COMMAND 'MD MH H72 C75'
Sets the mode to Hold with settings of heat setpoint 72F and cool setpoint 75F.
Sets the 7-day program. The Master sends the ?PG command to request the value of a program configuration setpoint.
Syntax:
PG D<Day> SP<DaySP> HT<HeatSP> C<CoolSP> HM<HSP> DM<DSP> T<Time>
Variables:
Day = Day of the week. An integer with a value of 0-6 where 0 = Sunday, 1 = Monday, etc.
DaySP = Time of day for a setpoint. An integer with a value of 1-4 where 1 = Wake, 2 = Leave,
3 = Return, and 4 = Sleep.
HeatSP = Heat setpoint for this day and setpoint. An integer with a value in degrees reported in the set temperature
scale, F or C.
CoolSP = Cool setpoint for this day and setpoint. An integer with a value in degrees reported in the set temperature
scale, F or C.
HSP = Humidify setpoint for this day and setpoint with a range of 0-100.
DSP = Dehumidify setpoint for this day and setpoint with a range of 0-100.
Time = The hour and minutes using a 24-hour clock for the start time of each setpoint
Example:
SEND_COMMAND 'PG D0 SP3 HT68 C72 HM30 DM50 T1900'
Sunday night setpoint, heat setpoint: 68F, cool setpoint: 72F, humidify setpoint: 30% RH, dehumidify setpoint: 50% RH,
7:00PM start time.
SEND_COMMAND '?PG D4 SP1'
The Master requesting the program configuration for the Thursday Wake setpoint.
Sets the current barometric pressure.
Syntax:
SEND_COMMAND 'PRESSURE <VAL>'
Variable:
VAL = The barometric pressure. This value should correspond to the currently used unit of measure.
Examples:
SEND_COMMAND 'PRESSURE 29.85'
Retrieves the 16-byte serial number set on the thermostat. The Master sends the ?SERIAL command to request the
thermostat's serial number.
Syntax:
?SERIAL
Example:
SEND_COMMAND '?SERIAL'
The Master requesting the thermostat's serial number.
SEND_COMMAND 'SERIAL 1234567890123456'
The thermostat returns the serial number 1234567890123456.
