Crestron CHV-TSTATEX-FCU infiNET EX Thermostat (Fan Coil Unit) infiNET EX Thermostat (Fan Coil Unit): CHV-TSTATEX-FCU Introduction The CHV-TSTATEX-FCU is a wireless thermostat featuring infiNET EX® technology. The CHV-TSTATEX-FCU installs just like a conventional thermostat because no extra wires are needed to connect to the control system. Although functional as a standalone thermostat, the CHV-TSTATEX-FCU delivers enhanced functionality as part of a complete Crestron® automation system.
infiNET EX Thermostat (Fan Coil Unit) Crestron CHV-TSTATEX-FCU Fan Coil Unit Support The CHV-TSTATEX-FCU infiNET EX thermostat provides the functionality of controlling fan coil units1. The CHV-TSTATEX-FCU has custom firmware, display programming and terminal labels designed for 3-speed fan applications. The CHV-TSTATEX-FCU supports on/off control of the valves and the fan in 4-pipe fan coil applications, eliminating the need for an additional device dedicated to controlling the fan coil unit itself.
Crestron CHV-TSTATEX-FCU infiNET EX Thermostat (Fan Coil Unit) Remote Sensors Optional remote temperature sensors can be connected to the CHV-TSTATEX for enhanced flexibility and optimized performance. Climate can be regulated according to an average of multiple sensors, or the built-in sensors can be disabled entirely to allow the CHV-TSTATEX to be installed out of view. For heat pump-type systems, outdoor temperature can be monitored to optimize system performance.

Crestron CHV-TSTATEX-FCU infiNET EX Thermostat (Fan Coil Unit) Operation System Mode The MODE button on the CHV-TSTATEX-FCU cycles the unit through all available system modes in the following order: Off, Heat, Emergency Heat (for heat pump and dual-fuel systems), Cool and Auto (if enabled in Setup). The system mode changes upon release of the MODE button and the selected mode becomes operational 5 seconds after the mode has been entered. Off Mode In Off mode, all HVAC systems are disabled.
infiNET EX Thermostat (Fan Coil Unit) Crestron CHV-TSTATEX-FCU Dual Setpoint Auto Mode (“AU” = “d” in Setup Mode) In dual setpoint Auto mode, separate heat and cool setpoints are used. When the ambient temperature drops below the heat setpoint, the unit calls for heat to maintain the heat setpoint. When the ambient temperature rises above the heat setpoint, the unit does not call for cooling until the temperature exceeds the cool setpoint.
Crestron CHV-TSTATEX-FCU infiNET EX Thermostat (Fan Coil Unit) If the or button is held down for 2 seconds, the unit enters an auto-repeat state and the setpoint adjusts rapidly until the button is released or until the upper (or lower) limit is reached. Some users want to have setpoints change automatically based on the day of the week and the time of day. For example, in the winter they may want to lower the heat setpoint while they sleep to lower heating costs.
