Field Programming Parameters: Access Code 79
Explanation of Codes:
Temperature Scale (Unt):
Selects scale parameter that will be shown
F - Default,°F
C - °C
On Power Interrupt (OPi):
Selects whether the thermostat will go into economy mode or
occupied mode after a power interrupt
EC – Default, thermostat will go into economy mode after
a power interrupt
OC – thermostat will go into occupied mode after a power
interrupt
Display Temperature (dSp):
Selects which temperature is shown on display
SP - Default, display will show setpoint only
rt - display will show room temperature unless either up or
down arrow button is pressed. Then the display will show
setpoint.
Srt - display will toggle between room temperature and
setpoint. Display will revert to setpoint when either the up or
down arrow button is pressed.
Temperature Control Mode (HAc):
USr - Default, switch selectable, heat only, auto changeover
or cool only
Aut - auto mode only
CL - cool mode only
Ht - heat mode only
Stop Function Enabled (Stp):
Selects whether or not thermostat can be turned off by pressing
the fan button
Ena – Default, enabled, press fan button until Stp appears
on display
dis – disabled
Economy Function Enabled (ECo):
Selects whether or not thermostat can be manually placed in
economy mode by pressing the fan button
Ena – Default, enabled, press fan button until Eco and
ECON appears on display
dis – disabled
Comfort Setpoint (CS):
Selects setpoint default temperature when thermostat powers up
or returns to comfort mode from economy mode
72.0°F (22.0°C) Default
Programmable Range: 60.0°F to 85.0°F (15.5°C to 29.5°C)
Cooling Limit (LC):
Selects minimum room temperature in cooling
65.0°F (18.5°C) Default
Programmable Range: 60.0°F to 85.0°F (15.5°C to 29.5°C)
Heating Limit (LH):
Selects maximum room temperature in heating
85.0°F (29.5°C) Default
Programmable Range: 60.0°F to 85.0°F (15.5°C to 29.5°C)
Freeze Protection (FP):
Selects freeze protection enabled or disabled
Ena – Default, enabled at 40°F
dis – disabled
Fan Purge Timer (FPt):
Selects the amount of time the fan will continue to run after a
heating or cooling call.
30 seconds Default
Programmable Range: 0 (Off) to 180 seconds (3 minutes),
in 10 second increment
Clear Logged Data (CLr):
Selects whether or not the logged run time data will be reset to 0’s
NO – default, no reset
yEs – reset
Energy Savings Preset (ESp):
Presets the stepped back functions according to the required energy
savings level. One of three presets can be chosen or skip this
parameter and go directly to the Sbr parameter to begin choosing
other non-preset settings.
L1 – (least energy savings)
Setback Ramping (Sbr): enabled
First Setback Timer (FSt): 480 minutes (8 hours)
Second Setback Timer (SSt): 60 minutes
Degrees Per Setback (dPs): 1.0°
This means that after 8 hours of no motion sensed the thermostat
will begin to step back at a rate of 1.0° every 60 minutes until either
the unoccupied cooling limit (UCL) or the unoccupied heating limit
(UHL) is reached.
L2 – (moderate energy savings)
Setback Ramping (Sbr): enabled
First Setback Timer (FSt): 240 minutes (4 hours)
Second Setback Timer (SSt): 60 minutes
Degrees Per Setback (dPs): 1.0°
This means that after 4 hours of no motion sensed the thermostat
will begin to step back at a rate of 1.0° every 60 minutes until either
the unoccupied cooling limit (UCL) or the unoccupied heating limit
(UHL) is reached.
L3 – Default (most energy savings)
Setback Ramping (Sbr): disabled
First Setback Timer (FSt): 60 minutes
This means that after 1 hour of no motion sensed the thermostat
will go directly to either the unoccupied cooling limit (UCL) or the
unoccupied heating limit (UHL)
Setback Ramping (Sbr):
Selects setback function to step back to unoccupied setpoints or to
go directly to unoccupied setpoints.
dis - Default, disabled, directly to unoccupied setpoints
Ena – enabled, steps back to unoccupied setpoints
First Setback Timer (FSt):
When in occupied mode, selects the amount of time when no motion
is detected before the setpoint begins to be stepped back by the
degrees per setback
60 minutes Default
Programmable Range: 1 minute to 720 minutes (12 hours),
in 15 minute increments
