ITEM #03 (THERMOSTAT TYPE): [PROGRAMMABLE, default] Use this setting for
following a daily program routine. [MANUAL] This setting omits the program
routine and operates as a manual style non-programmable thermostat. This is
very basic and only shows the room temperature and set temperature on the
screen, with no clock.
ITEM #04 (PERIOD QUANTITY): [4P, default] Thermostat uses four periods per
day (called MORN, DAY, EVE, and NITE). [2P] The thermostat uses two periods per
day (called DAY and NITE).
ITEM #05 (EARLY RECOVERY): [OFF, default] Program Set Temperature values
start to occur at exactly the period start times. [ON] Early Recovery affects how
the transition occurs when changing from the NITE to the MORN period, and
when changing from the DAY to the EVE period. The thermostat calculates how
long it takes for your home to recover from a setback on a daily basis, and turns
on ahead of time in order to reach the target set point of the next upcoming
program period by the period’s start time. While in a recovery, the word
“RECOV.” will be shown on the display screen.
ITEM #06 (SYSTEM MODE): [FURN, default] This is for the majority of heating
systems that are not Heat Pumps, such as a gas furnace or hot water boiler. [HP]
Use this setting if you have a Heat Pump system, which uses the outdoor unit as
the primary heat source and may also contain an electric heating element as a
backup heat source. When set to “HP”, ensure that you have also set the
Gas/Electric circuit board option to “ELEC”, as described in the “COMPLETE THE
INSTALL” section.
ITEM #07 (FAN “G” TERMINAL OPERATION): This setting changes how your
system’s blower fan (if applicable) is controlled while the thermostat is in HEAT
or EMERG HEAT mode, when the Fan switch in the AUTO position. This setting
does not affect the fan operation while in COOL mode.
[GAS, default] The blower fan is controlled solely by the heating system itself.
Systems that would typically use the “GAS” setting would be: natural gas,
propane, or oil furnaces, and boilers.
[ELEC] The blower fan is controlled directly by the thermostat. This setting is
required for heating systems that do not control their own fan, such as HEAT
PUMPS, and units that only have an electric-resistive heating element as the heat
source.
NOTE: If your blower fan does not operate properly after installation, try changing
the GAS / ELEC option to the “ELEC” setting.
