Thermostat is not following schedules properly

If a thermostat is not following the schedules properly, try the following steps.

Verify the thermostat has proper Z-Wave communication

Verify the thermostat is communicating properly with the Z-Wave network. A good test for this is sending a remote thermostat setpoint change command or two to the thermostat. If the thermostat setpoint updates, Z-Wave communication is likely stable.

Poor Z-Wave communication

If Z-Wave communication is poor, increase the Z-Wave communication quality.

For information about increasing the Z-Wave communication, see the Repairing the Z-Wave Network section of any Z-Wave install guide in Z-Wave.
If the Z-Wave device is in malfunction, see Z-Wave device is in malfunction or offline.

Good Z-Wave communication

If Z-Wave communication is good, log in to the Customer Website to verify the customer's schedule is set up properly.

Verify the schedule is set up properly

Verify the thermostat schedule is not set to have the same temperatures in adjacent intervals. For example, if the user wants the temperature to change according to the schedule if there is a manual change, do not set the adjacent intervals to be 70 degrees four times in a row as shown in the following image for the Weekday.

Note: If using Celsius, temperatures can be set in 0.5 degree increments. Verify adjacent intervals are at least one degree different if the user wants the temperature to change according to that scheduled interval.

If the target temperature on the schedule is the same on two or more adjacent intervals, it reads those adjacent intervals as one large schedule interval. For example in the preceding image:

On a weekday, if the thermostat is manually changed to 74 degrees at 8:00 AM, the target temperature stays at 74 degrees until 10:00 PM since that is the next scheduled interval that has a different temperature. The thermostat does not resume the schedule at 10:00 AM to change the target temperature to 70 degrees since the Weekday target temperature is identical with the preceding adjacent interval (i.e., both intervals are set for Open at 70 degrees).
Versus on the weekend, if the thermostat is manually changed to 74 degrees at 8:00 AM, the target temperature changes according to the schedule at 10:00 AM since the Weekend adjacent intervals are set to different target temperatures.

If the user wants each interval to trigger the schedule when manual changes occur, verify that adjacent intervals are set to different target temperatures.

Send a hard reset

If Z-Wave communication and schedule configuration are both good, try sending a Hard Reset to the panel using the Remote Toolkit. For more information about sending a Hard Reset, see Send a Hard Reset command to a module.

After the user's module reboots from the Hard Reset, disable the thermostat schedule, wait 5 minutes, and then enable the thermostat schedule again.

Verify if the thermostat may have an internal schedule

If all preceding steps have not resolved the behavior with the thermostat schedule, verify whether the thermostat has its own schedule programmed into it. The installation or user guide for the thermostat should note if the thermostat can have an internal schedule or not. Some thermostats are listed in the following table, Internal thermostat schedule information.

Internal thermostat schedule information

Thermostat	Internal schedule?	Troubleshooting
CT-100	No	N/A
Alarm.com Smart Thermostat	No	N/A
CT-30	Yes	If internal schedules are enabled, the thermostat displays the time in the upper left corner (normal mode). To turn the schedules off, put the thermostat into simple mode: If the CT-30 is in COOL or HEAT mode, press the MODE button on the right side of the thermostat until it reads OFF. Press and hold PROG for at least 12 seconds to put the thermostat into simple mode (internal schedules off).
TBZ48A/Linear NTZB48	Yes	If the thermostat shows away beneath the temperature, internal schedules are enabled. Turn this off by holding the MODE button for at least ten seconds. Away will disappear.
TZEMT400	Yes	To see if internal schedules are enabled, press and hold the middle two buttons simultaneously until Installer Settings is displayed, then scroll to System Settings and press Select. If Sched Enable says Y, press the - button until it says N, then press Done to save changes.
