You'll see the current temperature displayed on the left, and can raise or lower it with the plus and minus buttons to the right -- red for heating and blue for cooling. When you've made changes to this device, you'll see the bottom of its Dashboard display to let you know the communication between the thermostat and your Smart Controller was successful.
From here, you can also remotely control the thermostat's current running mode. Since this is a smart thermostat, there are multiple ways of controlling the climate, beyond simply changing the temperature.
You'll see three columns of functions for the ZTS-100, in addition to the plus and minus buttons to the right for heating and cooling.
LEFT COLUMN (Modes for the thermostat)
Off: Turns the thermostat (and your heating/cooling system) off.
Auto: This engages timed settings and climate preferences that you choose on the actual thermostat.
Cool: Tells the thermostat to turn on the cooling system.
Heat: Tells the thermostat to run the heat.
CENTER COLUMN (Modes for the fan)
Auto: Tells the thermostat to turn the fan on and/or off to achieve the desired temperature.
On: Tells the thermostat to keep the fan running continuously.
Cycle: To protect the compressor or heat pump, those outputs forced off until a three minute count down is finished. After the three minute cycle, the heat or cooling returns to normal operation.
Normal: The ZTS-100, and your heating/cooling system, is running normally.
Energy: This feature is not implemented in every thermostat, and is not implemented in the ZTS-100. Its energy saving capabilities lie in the control you have, remotely or automatically; especially the Mon-Fri "weekday mode" and the Sat-Sun "weekend" mode.
NOTE: Full, detailed documentation on the ZTS-100's various operating modes can be found by downloading the PDF attached at the bottom of this page.
