Crestron CHV-TSTATRF infiNET™ Thermostat Basic Setup Basic Thermostat Setup The following documents the most common CHV-TSTATRF setup requirements. For full details on all setup options, refer to “Advanced Setup” which starts on page 18. Install two AA batteries (supplied) in the battery compartment. NOTE: When first setting up the CHV-TSTATRF, batteries are required, even if you plan to power it from a constant 24 VAC supply.
infiNET™ Thermostat Crestron CHV-TSTATRF If you have wired the thermostat so that 24 Volts AC will always be present on the “C” terminal (refer to “Wiring the CHV-TSTATRF to the HVAC System” on page 10), you can set the unit to run from this power supply, thus eliminating the need for batteries (except during initial setup). The thermostat will run on battery power if 24 VAC is not present.
Crestron CHV-TSTATRF infiNET™ Thermostat NOTE: An infiNET device can be acquired by only one gateway. Put the C2N-MNETGW in the Acquire mode, from the unit itself by pressing ACQUIRE or from Toolbox, as described in the latest revision of the C2N-MNETGW guide (Doc. 6317), which is available for download from the Crestron website (http://www.crestron.com/manuals). The gateway ACQUIRE LED lights.
infiNET™ Thermostat Crestron CHV-TSTATRF Advanced Setup Setup Mode After the CHV-TSTATRF is installed, it is necessary to set it up for a particular heating/cooling system. Please note that some of the setup parameters listed below will not always be available. Refer to “Setup Mode Parameters/Functions”, which starts on page 19 for details. Place the CHV-TSTATRF in the Setup mode by doing the following: 1. Press and hold the FAN button. 2.

Crestron CHV-TSTATRF infiNET™ Thermostat Appendix: About Heat Pumps A heat pump extracts available heat from one area and transfers it to another. Even cold air contains some heat and heat pumps can extract heat from the outside air on a cold day and transfer it indoors to maintain a comfortable temperature. A heat pump also works in reverse during the summer, extracting heat from indoors and transferring it outdoors.
infiNET™ Thermostat Crestron CHV-TSTATRF Glossary Anticipators Used to anticipate the drop or rise in temperature and energize the appropriate system before reaching the set point. Anticipators affect how tightly the setpoint temperature is maintained. Balance Point At low outdoor temperatures, the refrigeration cycle of a heat pump will not be able to supply the heating requirements without the aid of a supplementary heat source.
Crestron CHV-TSTATRF infiNET™ Thermostat HVAC Heating, ventilation and air conditioning. Interstage Differential The proportional temperature error (0.5 to 3.0º) to trigger the second stage (2-stage only), such as the aux heat for a heat pump type system. Run Fan in Heat Calls (Run Fan in Ht Calls) A device setting that activates the fan output during heat (W) calls. (For heat pump or dual fuel system types, this setting activates the fan during calls for auxiliary heat.
