On the thermostat’s circuit board, there is a row of DIP switches, labeled #1
through #9. 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.
