If Zone ## Current Temperature > XX
Condition is true if the current temperature of the specified HVAC zone is greater than the value XX
(a number from 0 to 255).
If Zone ## Current Temperature = XX
Condition is true if the current temperature of the specified HVAC zone is equal to the value XX (a
number from 0 to 255).
If Zone ## Current Temperature <> XX
Condition is true if the current temperature of the specified HVAC zone is not equal to the value XX
(a number from 0 to 255).
If Zone ## Temperature Setting < XX
Condition is true if the temperature setting of the specified HVAC zone is less than the value XX (a
number from 0 to 255).
If Zone ## Temperature Setting > XX
Condition is true if the temperature setting of the specified HVAC zone is greater than the value XX
(a number from 0 to 255).
If Zone ## Temperature Setting = XX
Condition is true if the temperature setting of the specified HVAC zone is equal to the value XX (a
number from 0 to 255).
If Zone ## Temperature Setting <> XX
Condition is true if the temperature setting of the specified HVAC zone is not equal to the value XX
(a number from 0 to 255).
EnerZone StatNet Thermostats
If you can leave your PC running, you can control EnerZone StatNet thermostats. Refer to the file "StatNets"
installed in the HomeVision directory for details.
Custom Thermostat Control
As discussed in previous sections, the controller can automatically control zones 1 and 2 if they use RCS
TX10, TX10-B, TX15, TX15-B, or serial thermostats. If you have different thermostats, you can still use the
TV Thermostat Control Screens to control them, but you will have to write your own macros to do this. Even
if you do use these RCS thermostats, you may want to modify the way the automatic control works (although
this is rarely needed).
To do this, you have to write your own macros that perform all the commands, and use your own variables to
hold the data (mode, temperature, etc.). If you wish to do this, you should read two files installed in the
application directory first:
1) The "Video Screens" file, which describes the general process of how the TV Thermostat Control
Screens work.
2) The "How To" file, which contains a detailed description of how to control the RCS TX10-B
thermostat. It was written before we added all the thermostat commands, so it does everything
using the basic X-10 commands. Use this as a guide in determining what to implement and how.
