NEW AND IMPROVED FEATURES
Your new electronic thermostat has been made even better by the
introduction of several new and improved features. Building on its
reputation for efficient and dependable operation, your thermostat
now offers the following list of enhancements.
Thermostat and Sensor Calibration
Release 3 provides easy calibration of the thermostat and remote
sensors. Simply press and hold the FAN button for 10 seconds
and adjust with the ✟ or ✞ buttons.

GENERAL INFORMATION

The thermostat normally displays room temperature, mode of
operation and whether cooling or heating is currently on. The
six buttons on the front of the unit allow complete control of
your equipment.
You may select different heating and cooling setpoints for the
system to maintain, e.g., 70° in heating and 75° in cooling.
Raising or lowering the setpoints in heating or cooling is as sim-
ple as pushing a button. In addition, you may choose to display
the temperature in °F or °C.
The thermostat also allows you to select continuous fan operation
(useful when using an air cleaner), or have the fan come on with
the equipment.
