Honeywell TH8320ZW

I just purchased this device and I am able to control it but, have not been able to schedule it. I have configured set points on the scheduling tab for the device but, they are not updating the thermostat. I went into the thermostat programming and enabled scheduling so I could see the schedules but, it still did not display the schedule I was setting up on the device itself. Anyone else have problems with scheduling?

I have 2 in a Multi-Zone setup controlling a 10 year old Climate Master GeoThermal Unit with D-Superheater and while playing this is what I found. In Manual Mode with all scheduling disabled in actual thermostate config not Vera set 0160 to 0 Nonprogramable. I then set the mode to heat basicly setting manual mode and not the Auto on the TH8320zw1000 I Seemed to set the temp in the Schedlue tab in the VERA3 Device setup. Hoever I found i got better results by using the Scenes and setting the system to auto (and I Force my fan on), Setting Heat temp and cool temp and them changing scenes based on time of day and turning hot water heater on and off as needed so i could get my free hot water off the D Super heater side of Geo.

I Would like to see the Thermo be fully programable like it is fromthe screen but This is one of the Best Standalone thermostats to begin with the ZWave just gave me another way to control.

I Am Going to re-enable the Scheduling at the Stat on both of them and then just control vaction mode and any overrides remotely. Using the very powerfull scheduler it already has.

KingBob - Have you had any luck with treating the thermostat this way? This is the same thing I want. I like the default scheduling tools on the device, but I want the ability to put the thing in and out of Permanent Hold. Or for that matter, a way to say ‘return to schedule’ after mucking with the setpoint, as if I had pushed ‘cancel’ from the display.
Any ideas where we can get more info on writing custom interfaces, if these features aren’t easily available?..??..

EngDave, have you figured out how to “return to schedule”? I’m having the exact same problem with my TH8320ZW1000. I’m running it with the thermostat schedule programmed and using the Z-wave control only to overrride/tweak it. I want my tweaks to be temporary, ie., to revert to the programmed schedule when the next time slot comes up. The unit does display “temporary hold”, but it keeps it indefinitely past the next schedule slot. The only way I found to return to the programmed schedule from the thermostat is to hit “Cancel” on the display. I would love to be able to control this from the my Vera, but right now, it seems useless if I cannot revert back to the programmed schedule.

Sorry ZMaF, no dice.
To be honest, I gave up on the quest and just use the thing a little differently because of the limitation. Sucks - I know, but I don’t know where to turn to get more information on the tStat.

@ZMaF

I have had good results by disabling all schedules on the thermostat itself (I don’t remember the setting #) and setting up scenes in the Vera instead. I can manually change the setpoint on either the thermostat or the Vera and when the Scene runs it goes back to the appropriate scheduled setpoint.

It is personal preference but I think it is much easier to create a scene on the Vera than to program the schedule on the thermostat.

Trotsky40,
Thats what i Ended up Doing. Still a bit fustrating. I’m guessing they added z-wave the the existing modle and had to drop other functions (Humidity Control) to fit the z-wave interface. Thus religating the Z-wave as another manual (all be it Remote) way of controlling interactive interface.

I’ve had mixed results with this solution. Using a Scene, I set the LUUP code:

local thermostatDeviceNo = 10 
luup.call_action("urn:upnp-org:serviceId:SwitchPower1", "SetTarget", {newTargetValue = "1"}, thermostatDeviceNo)
luup.call_action("urn:upnp-org:serviceId:SwitchPower1", "SetTarget", {newTargetValue = "0"}, thermostatDeviceNo)

The default behavior appears to be that any setpoint you do via a Vera will exist until the next local schedule (temporary hold). The code above cancels your intervention whether it was manual or by Vera, kicking back to the current locally scheduled temp. It appears to work by setting the thermostat to “Energy” mode and back. However, just doing the same by the user interface does not work.

FYI, the only way I am able to simulate a Permanent Hold from Vera is to set the Min and Max temps. And if a Permanent hold is set on the device, I haven’t been able to appropriately get it back to schedule.

We use local schedules on 8 thermostats and override them using the Vera manually, via schedules and/or using a GCal plug in (allowing basic scheduling by office staff of a Google Calendar without access to the Vera itself). So far the biggest frustration has been intermittent erroneous Low and High temp notifications where the Tstat reports a current temp of zero (triggering our low temp warning we use for when the boiler goes offline) or a temp of >5000.

Good luck.
