V. THERMOSTAT CONFIGURATION
This thermostat has been carefully confi gured at the factory to provide
optimum operation for most installations. The settings programmed
into it at the factory should NOT be changed unless determined to
be absolutely necessary by a qualifi ed HVAC contractor.
VI. CHANGING THERMOSTAT CONFIGURATION
If it has been determined that re-confi guration of the thermostat
is required, the following instructions will assist the professional
HVAC installer in accomplishing this task:
While in confi guration mode, three option choices can be made:
A
Anticipator Value Adjustment
d
Display temperature Fahrenheit/Celsius Selection
o
F
Offset Adjustment for Room Temperature
r
C
Cycle rate. Maximum number of cycles per hour
TO ENTER THE CONFIGURATION MODE:
Press and hold the FAN button for approximately 10 sec until
“A"
room temperature disappears and the display reads
. You
are now in the confi guration mode.
NOTE: If the FAN button is pressed again or if no button is
pressed for 2 minutes, the thermostat will exit the confi gura-
tion mode and return to normal operation. To re-enter the
confi guration mode, the FAN button must be pressed and
held for 10 sec. again.
WHILE IN CONFIGURATION MODE, THE FOLLOWING
OPTIONS ARE AVAILABLE:
A
. ANTICIPATOR - Value Adjustment
This adjustment controls the sensitivity and cycle rate of the
thermostat. Higher numbers decrease the sensitivity and slow
the cycle rate. Lower numbers increase the sensitivity and
increase cycle rate. However, a limiting feature will not allow
more than 4 equipment cycles per hour, regardless of setting.
Values can range from 1 to 3. Factory default setting is 2. This
default selection will provide optimum performance in nearly
all installations. Try it fi rst. Do not change setting unless there
is evidence of need to do so. Unlike conventional anticipators,
this setting is not determined by current draw. There is no need
to measure, know, or compensate for current.
TO ADJUST:
1. Enter confi guration mode (if not already there).
