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 are always be present on the 24C

terminal, slide the POWER switch to 24VAC. No batteries are required in this

mode.

NOTE: When the unit detects 24 Vac, it no longer “sleeps”, meaning it offers 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 is also seen when switching from

STEAL to 24VAC. This is normal and the discrepancy disappears within

approximately 10 minutes.

Wiring the CHV-TSTATEX-FCU 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 the system being connected does not match any of the

systems described below, contact Crestron Technical Support for assistance.
