Crestron CHV-TSTATEX User Manual

Crestron CHV-TSTATEX infiNET EX™ Thermostat
NOTE: Steal Power mode may cause problems with some types of HVAC systems,
such as indicating a false heat or cool call. If this occurs, do not use Steal Power
mode.
If the thermostat will be wired so that 24 Volts AC will always be present on the 24C
terminal, slide the POWER DIP switch to 24VAC. No batteries will be required in
this mode (except during initial setup),
NOTE: When the unit detects 24 VAC is present, it will no longer “sleep”, meaning
it will offer real-time communication with the control system.
NOTE: When the unit is powered from a constant 24 VAC supply, there may be a
slight discrepancy between the ambient temperature displayed on the thermostat and
the actual room temperature. This discrepancy will also be seen when switching from
STEAL to 24VAC. This is normal and the discrepancy will disappear within
approximately 10 minutes.
Wiring the CHV-TSTATEX to the HVAC System
Make the necessary connections as called out in the illustrations that follow. A flat
head screwdriver (not supplied) is required to attach the control wires from the
HVAC system. Apply power after all connections have been made.
The illustrations on the following pages show examples for connection to various
types of HVAC systems. If your system does not match any of the systems described
below, contact Crestron Technical Support for assistance.
