Temperature and Humidity Sensors
The clock includes a temperature and humidity sensor, as shown in Figure 3.
Temperature and humidity are greatly influenced by direct sun and radiant heat from the wall it is
attached to.
We recommend mounting the clock in a protected, shaded area to insure accurate temperature and
humidity.
