I agree that the words sound backwards. However, on my CT-100, my colors match yours but the words are the opposite. (i.e., Green/Heat when idle; Orange/Heating when actively heating). Interesting that your verbiage is the opposite.
Does this device (and/or handler) tell ST when the HVAC kicks on?
Yes it does but note thatās itās up to the thermostat to tell the hub. The
DH just translates what the device tells the hub and reports it
appropriately to update the state.

Very awesome. I always hated that slider! Thank you!
By the way, I have found since installing this radio thermostat CT-30 tstat that my unit will no longer heat normally. Every time I turn on the heat, it puts the air handler in AUX mode. I called out an AC guy and they could not figure it out, but they confirmed itās the thermostat by swapping with a known-good. Anyone have any ideas?

You may have configured your CT-30 with Aux Heat or Emergency heat options while installing it. Check the manual below to see how to setup the right configuration, through the jumper pins and the automated setup options:

I think I may have figured out an issue Iāve had with CoRE detecting my HVAC fan being set in ON mode, instead of AUTO. When I go to setup the piston, my trigger options are on, auto, and circulate. However, when I look at the device log, I see that the thermostat fan mode is set to āfanOnā.
Since On != fanON, could that be causing CoRE to not detect the change?
Yes but itās better to check with the CoRE support forum as Iām not intimate with CoRE internals. The states are
Fan:
fanOn
fanAuto
fanCirculate
HVAC:
off
heat
emergencyHeat
cool
auto

http://docs.smartthings.com/en/latest/capabilities-reference.html#thermostat-fan-mode
states that the attributes should be on, auto, circulate for the thermostatfanmode.
the commands to change the mode are fanOn(), fanAuto(), etc, or setThermostatFanMode(āonā), etcā¦
so if an attribute is returning fanOn as a string, that is likely a bug in that dth; not CoRE

Yup looks like ST changed the specs sometime recently, the original documentation/DTH were fanOn/fanAuto which was subsequently changed to on/auto etc on March 29th. Will update the DTH, thanks for reporting it. I wish ST would publish changes to the fundamental attributes etc @Jim
#IMPORTANT UPDATE
###Enhanced Z-Wave Thermostat with Temperature, Humidity and Auto Time setting - Version 02.07.00
- Updated attributes to match the new ST standards (PLEASE click on
Configureand thenRefreshto activate changes after updating code) - Added support for Health Check feature in ST
- Patch for CT-xxx thermostat firmware defect, now the Fan and HVAC operating status will update when settings are changed
- Fan now shows running/off state even when in Auto mode
- Updated icons and color scheme to match STās recommendations
###After updating the code DO NOT FORGET these 2 steps otherwise your thermostat may not operate properly. This is required due to changes in ST standards. Open the device on the ST phone app:
- Click on
Configurebutton, wait 5 seconds - Click on
Refreshbutton, wait 5 seconds
Now you can use your updated thermostat, enjoy!

Thanks Rboy for keeping up with the changes!
In this app is the option for fan circulate. Is that using a setting on the thermostat to control the cycle, or is the app controlling the cycle?
I have a CT-100 and wanted to see how cycling the fan would make the house feel. Otherwise, Iāll use your fan schedule app.
Thanks again

Just as a UI suggestion, if you drop the word āFanā it should fit in the circle.
Auto
On
Circ

yes the device handler supports all the options in the stock ST DH plus more including the Circulate option
Yes we noticed that too but the words are part of the new image which is provided by ST, the other option would be to revert back to the old circle style with words and the fan image.

Cool. Where in the app is the setting for on/off times of Circ?
This isnāt an app itās a device handler, i.e. it allows ST to communicate with the device. Consequently if the device supports circulation mode (ct-xx devices donāt support it) it will allow you to set the thermostat fan to circulation mode. Z-Wave specs dontā have a standard for circulation settings (beyond humidity circulation and regular circulation). If thereās a specific thermostat that supports circulation settings using parameters, do let us know (along with the docs preferably) and we will add support for it.
So my CT30 seems to refuse to send (manual) fan events to ST. Can I assume thatās a limitation of the device? Iāve sorta solved it by having CoRE send a refresh command every 7 minutes.
any chance you can increase the font size of the temperature on both of. āmy homeā as well as the actual thermostat page. There are these huge colored buttons but the font is so small. Itās in sharp contrast to the humidity and battery gauge where the font is actually too big for their respected buttons
These are issues with the ST app. They broke it with latest release, it was working fine with the previous release. Please report it to ST support so they can prioritize fixing it. I have reported it to ST also but they will need more tickets before they fix it.
