(please see the diagram below).

The 1st Stage of heat or cool is turned on when:

( A ) The temperature spread from the setpoint is equal to or greater

than: the setpoint plus the 1st stage deadband (step #6, page 13).

This 1st stage deadband is adjustable from 1-6 degrees and the

default is two degrees.

The 2nd Stage of heat or cool is turned on when:

( A ) The 1st Stage has been on for a minimum of two minutes .

And

( B ) The temperature spread from the setpoint is equal to or greater

than: the setpoint plus the 1st stage deadband (step #6, page 13),

plus the 2nd stage deadband. This 2nd stage deadband is fixed at

two degrees and is not adjustable.

BATTERY ELIMINATOR (optional accessory) - t he ACC0800 RF power

supply adaptor is used to power the thermostat and eliminate the need

for replacing batteries each year. Use only the Venstar accessory

ACC0800 for proper operation.

LOW BATTERY WARNING - The two AA lithium batteries must be replaced

at least once every 12 months to ensure proper operation. The “low

battery” icon (fig. 1) will appear on the display when it is time to replace

the batteries.

When the “low battery” icon is displayed the batteries must be replaced

immediately (see next page). The manufacturer cannot be liable for

improper operation of the thermostat if the batteries are not immediately

replaced. Annual battery replacement is especially critical in locations

subject to freezing temperatures. The thermostat will be unable to turn

on the heating system if the batteries are exhausted.
