Can't use REST to changes Thermostat TZ45R setpoints

My z-wave RCS Thermostat TZ45R will not respond to REST setpoint changes. I get a 200 response, but the setpoints don't change. I can set the mode via REST. I can change setpoints via the Admin Console and UDI Mobile. I have a Venstar thermostat that I can change setpoints on via REST. Am I doing something wrong?

Here's the REST node response

Here's the REST response from a setpoint change attempt. The response show the proper response, but the setpoint doesn't change. It's the same for Cool and Heat.
