| Overview

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.

| Precautions

  • 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.

| Mounting

The CTH mounts on a ceiling by a threaded bush.


The module drop is adjusted with a set screw. 


Installed Sensor 



| Wiring

 The sensor plugs into the standard 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 sensor 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.
