Heating, Cooling, and Relative Humidity Thermostat, DIN Rail Mount
The DIN‑THSTAT is a DIN‑rail mountable heating, cooling, and relative‑humidity thermostat. The DIN‑THSTAT provides control of radiant floor heat, forced air, and heat pump HVAC systems. DIN rail mounting allows for installation in an equipment cabinet, keeping the living area free from a wall-mounted thermostat. Small, unobtrusive remote temperature and humidity sensors1 gather the environmental conditions from the room and transmit the data to the DIN‑THSTAT.
The DIN‑THSTAT is a versatile heating, cooling and relative‑humidity thermostat that provides control of radiant floor heat, forced air, and heat pump HVAC systems. DIN rail mounting allows for installation in an equipment cabinet, keeping the living area free from a wall‑mounted thermostat. Small, unobtrusive remote temperature and humidity sensors1 gather the environmental conditions from the room and transmit the data to the DIN‑THSTAT.
A Crestron control system connection allows temperature adjustments from virtually anywhere by using a Crestron touch screen, handheld remote, mobile app, or computer.
Remote Sensors
The CHV‑RTS and CHV‑RTHS remote sensors provide indoor temperature and humidity data so that the DIN‑THSTAT can be installed out of view. The CHV‑RSS monitors outdoor climate and floor temperature, enabling outdoor low-temperature compensation to prevent condensation on windows during cold weather. The DIN‑THSTAT accepts up to three temperature sensors. Each sensor connects via a single twisted pair wire.
Auxiliary Ports
Auxiliary ports allow state sensing from HVAC equipment and interfacing with additional HVAC devices.
DIN Rail Mounting
The DIN‑THSTAT snaps onto a standard DIN rail for installation in a wall mount enclosure (Crestron DIN‑EN series or similar1) or on a wall panel. The DIN‑THSTAT is designed to mount in a DIN‑EN‑2X18‑HC‑OPEN, DIN‑EN‑3X18‑HC‑OPEN, or DIN‑EN‑6X18‑HC‑OPEN for an attractive centralized mounting solution. The hinged cover provides easy access to equipment wiring while openings in the cover provide access to the DIN modules through the cover.
Cresnet Communications
The DIN‑THSTAT communicates with a Crestron control system (such as the DIN‑AP3) via the Cresnet control network. A pair of Cresnet ports is provided on the DIN‑THSTAT to allow easy daisy‑chaining of several DIN‑THSTAT or Crestron DIN rail devices.
