On the thermostat’s circuit board, there is a row of DIP switches, labeled #1
through #8. The position of these switches will change how the thermostat
operates, and also how information is conveyed to you on the LCD display
screen. If you make any changes to these options, the changes are not
recognized unless you either: change the position of the HEAT/OFF/COOL mode
switch, or press the “HW RST” (Hardware Reset) button on the circuit board. The
use of this button is further described in the “ADVANCED FEATURES” section of
this manual.
These option switches are very small and should be moved carefully using
objects such as: eyeglass screwdriver, fine-point pen, toothpick, or similar. The
listing below describes the available choices for each option switch:
SWITCH #1 (SYSTEM): [OFF/DOWN = FURN, default] This setting is used for the
majority of all heating systems that are not heat pumps. Examples for this
setting would be: natural gas furnace, hot water baseboard heat, and oil heat.
[ON/UP = HP] Use this setting if you have a heat pump unit (which looks just like
an outside air conditioning unit, but is used for both cooing and heating).
SWITCH #2 (TYPE): [OFF/DOWN = PROG, default] The thermostat controls the
room temperature by following temperature program periods that you set up
based upon your daily routine. [ON/UP = MAN] The thermostat operates manually
just like a mechanical or non-programmable model. This method of operation is
very basic and only shows the room temperature and set temperature; there are
no temperature programs, days of the week, or clock times.
SWITCH #3 (PERIODS): [OFF/DOWN = 4, default] The thermostat uses four
temperature program periods in both heating and cooling (MORN, DAY, EVE, and
NITE). Each period has a separate start time and a set temperature. [ON/UP = 2]
The thermostat operates in the same manner as above, however there are only
two temperature program periods for heating and cooling (DAY and NITE). This
