CT100 Plus (Z-Wave Plus) vs the CT 101 (Z-Wave)
Okay an update on this, we’ve been testing the CT00 Plus for the past few weeks.
Things we’ve tested with the CT100 Plus (using the Universal Enhanced Z-Wave Thermostat device handler):
- Pairing and exclusion with v2 hub - passed. (NOTE: this device is about 400+ ft from the hub and has a few Z-Wave repeaters in between and it works great)
- Response to ST configuration commands - passed (minor documentation bug in the manual but no impact on operation)
- Response to ST commands, turn Fan On/Off, switch modes between Heat, Cool and Auto, Temp up/down - passed (NOTE: We found that the CT100 Plus is MUCH faster to respond to commands than the CT101, infact we could send it 2-3 temperature change commands per second compare to 1 for the CT101)
- Update from Thermostat local changes, tested change in modes, changes to fan states, changes to temperature settings - passed (NOTE: Once again we noticed that the response was faster with the CT-100 Plus)
- Run time updates - This is an area where some of the older CT-XX thermostats had issues. With the CT100 Plus when the fan mode in Auto would change or the A/C mode would turn on/off (running to idle or vice versa) it would update the ST hub immediately. This is a significant improvement over the CT-XX/CT101.
Overall the performance of the CT-100 Plus is significantly better than the CT-101, it’s more responsive and appears to have fixed some of the issues with the older thermostats.
When there is a switch over safety cool down period for the compressor, it displays it more prominently on the screen (the old model just had a small tiny timer which left you wondering what it was).
Having said all that, there is a cosmetic difference in the design, I’m posting pictures here for your reference. It has a larger form factor (about 10%). The Menu and Mode button are now touchscreen, you need to click on the touch screen to change the mode (it appears on the top left where the time clock used to be). If you’re using ST you probably won’t use this much but good to know. There is a slight change in the display, you’ll notice that the time is no longer displayed by default with CT100+ on the top left corner. There is now a setting that when changed on the thermostat now allows you to see now just the time and humidity like the original thermostat but also additional details like day of week and time of day (see screenshots below).
