CONFIGURATION

ADJUSTABLE ANTICIPATION

This option allows the cycle times in heating and cooling to be increased or decreased. The factory set values can be adjusted higher for longer cycles or lower for shorter cycles.

The adjustment range for HEATING is from 2 to 40. The factory preset is 5. The adjustment range for COOLING is from 9 to 40. The factory preset is

12.The recommended initial setting for hydronic (hot water or steam) systems is 35.

The cooling will not go below 9 because compressors require a longer cycle.

The chart below shows how this adjustment range affects thermostat performance.

COOL FAN-ON

AND FAN-OFF DELAY

This option allows a selection of a fan- on delay of 1 to 5 seconds on a call for cool and 1 to 127 seconds of fan-off delay after the thermostat has satisfied the call for cool.

Ashort delay to allow the A-coil to

cool off before the fan turns on may be preferred. This also allows the
