Installing Batteries
The Temperature Transmitter uses three AA sized batteries. For optimum battery life Hampshire
Controls Corp. recommends using lithium batteries such as Energizer Ultimate Lithium (L91) or
equivalent. The Temperature Transmitter will operate for approximately one year on a fresh set
of L91 batteries under normal operating conditions. High quality alkaline batteries may be used,
but with moderately decreased lifetime.
NOTE: The following conditions will shorten battery life.
•
RF interference or congestion in the 2.4GHz band (Wi-Fi).
•
Excessive time spent in an alarm state (flashing LED & chirping buzzer).
•
Excessive time spent in the Web Configuration or Calibration modes.
•
Excessive use of the LCD display (see Constant Display on page 12).
The battery orientation is shown in the diagram below.
BE CAREFUL TO INSERT THE BATTERIES IN THE PROPER ORIENTATION!
Do not mix batteries of different ages, types, or manufacturers!
