infiNET EX Thermostat: CHV-TSTATEX Operations & Installation Guide – DOC. 6989C
Remote Operation
As an infiNET EX device, the CHV-TSTATEX can be controlled remotely via a
Crestron control system. Most often, control of the thermostat is achieved via a touch
screen or Web-based graphical interface. In order to extend battery life, the
thermostat only communicates with the control system once every 30 seconds or
1 minute, based on the infiNET EX Sleep Time setting. Because of this, there is a
noticeable delay between the time a button is pressed on a touch screen and when the
thermostat reacts to the command. To account for this, the CHV-TSTATEX modules
written by Crestron and provided in the Crestron Database mimic the feedback from
the thermostat so that the user sees an immediate response on the touch screen.
Likewise, pressing a local button on the thermostat (for example, setpoint raise or
lower) does not cause an immediate change to the corresponding display on a touch
screen. Instead, the thermostat wakes up shortly after the last button press to send its
updated status to the control system.
If the thermostat is wired to have the optional 24 Vac at the 24C terminal and the
power switch is set for 24VAC, there is no delay in feedback.
