The Intelligent-Ceiling Temperature and Humidity Sensor (CTH) adds a high-precision temperature and humidity sensor pre-calibrated from the factory.
Placed holder for unboxing and installation Video.
- Install as per all state and local electrical codes.
- Do not mount the sensor head too close to the ceiling, this increases the stratification effect.
- Do not mount the sensor exposed to direct sunlight or any other heat source.
The CTH mounts on a ceiling by a threaded bush.
The module drop is adjusted with a set screw.
The sensor plugs into the standard 3wire sensor bus that 75F offers on its Nodes and Stats using the 3 Pin to 3 Pin cable of lengths 18 inches, 20, 30, and 50 feet, as shown below.
In principle, the CTH can be daisy-chained with other sensors on the 1-wire bus to provide an extensible sensor network.
With its capability to be a part of the daisy chain, combining it with other sensors in the bus, using the daisy chain adapter, and with 3 Pin to 3 Pin cable of lengths 18 inches, 20, 30, and 50 feet, the Ceiling Sensor can be made a part of the Daisy Chain.
