Fan Control (Heating)
0 – OFF for Heating (Gas/Oil Heat)
1= Electric Furnace (DEFAULT)
0 = 4 – 20mA
0: The thermostat will not activate the fan with a heating demand.
1: The thermostat will activate the fan with heat demand.
YD Output Configuration
Configures digital cooling output for 0-10VDC or 4-20mA DC
Configures digital heating output for 0-10VDC or 4-20mA DC
1 = 0 – 10 Volts (DEFAULT)
WD Output Configuration 0 = 4 – 20mA
1 = 0 – 10 Volts (DEFAULT)
0 = 4 – 20ma
1 = 0 – 10 Volts (DEFAULT)
GD Max Voltage, Heating 6 – 10 VDC (Default: 8)
Demand 12 – 20 mA (Default: 20)
GD Max Voltage, Cooling 6 – 10 VDC (Default: 10)

Depending on SM 124 setting, sets Fan HI speed voltage or current (mA) at terminal GD with
demand for Heat.
Depending on SM 124 setting, sets Fan HI speed voltage or current (mA) at terminal GD with
demand for Cool.
Demand
12 – 20 mA (Default: 20)
GD Min Voltage
0 – 6 VDC (Default: 2)
4 – 12 mA (Default: 4)
Depending on SM 124 setting, sets Fan LO speed voltage or current (mA) at terminal GD
with no demand.
W1 Output Configuration
S1 Remote Sensor Input
0 - NC: Normally Closed Operation (Default)
1 - NO: Normally Open Operation
Reverses the ON/OFF operation for W1. NC operation powers on with a demand. NO
opreation powers off with a demand and will be on with no demand unless main power is
removed from the thermostat.
170
171
0= No Remote Sensors (Default)
0: Remote temperature sensing is disabled.
1: The T8168 uses the remote sensor only for temperature sensing.
2: The T8168 averages the local and remote sensor for temperature sensing.
When using a remote sensor an open or short will turn off outputs and display either
2Ero(open) or 2Erc (closed). Fault detection settings are not used.
1= Remote Indoor Sensor Connected
2 = Remote Sensor Connected And Sensor
Averaging
S2 Pipe Sensor
0 – Disabled (Default)
1 – Two Pipe Operation
Enables fan coil pipe sensor operation. Connect a PECO pipe sensor or dry switch closure for
change over from Summer (cold water) to Winter (hot water). 2-pipe operation uses the Cool
1 output for heating and cooling. Heat 1 is disabled. 4-pipe operation allows heat 1 in summer
mode of operation.
2 – Four Pipe Operation (use for 2-pipe with
electric heat relay)
Available when SM 110 = 1 through 5 or 14 through 16
172
173
174
Pipe Sensor Threshold for 50F to 72F (Default 60F)
Cooling
Changes to Cool when pipe temp is below threshold. Available when SM 171 = 1 or 2
Pipe Sensor Threshold for 75F to 90F (Default 80F)
Heating
Changes to Heat when pipe temp is above threshold. Available when SM 171 = 1 or 2
Pipe Sensor Purge
0 = Time (Default)
1 = Temp
TEMP: Purge continues until a non-ambiguous condition is sensed.
TIME: A 3-minute purge is started. Once complete and still ambiguous mode all thermostat
outputs are disabled for 1 hour.
Available when SM 171 = 1 or 2
175
240
Fault Detection/ Setback
0 = Disabled (Default)
1 = Active On Open
When enabled connect dry switch between S1 and SC.
Displays “Door” in clock location, turn outputs OFF, blink red LED
Displays “Fdd” in clock location, outputs function normally
Displays “Err” on clock location, turn outputs OFF blink red LED
Sets thermostat to setback with a closure at SC and S1 .
(requires SM170=0)
No remote probe
2 = Active On Open
3 = Active On Close
4 = Occupancy Sensor
2 or 4 Events (DEFAULT = 2)
Number of Program
Events
When the T8168 is set up as programmable this sets the number of events per day. Events
are OCC1, UNOCC1, OCC2, UNOCC2

Clock Format
F or C
12 or 24 Hrs (Default = 12)
0- Celsius
This service menu sets the clock format.
Determines temperature displays in Fahrenheit or Celsius
1- Fahrenheit (Default)
0-99 Seconds (0-Default)
270
280
Fan Off Delay Heat
Fan Off Delay Cool
The amount of time (in seconds) the lowest available fan speed will run after the
thermostat heating outputs are disabled
0-99 Seconds (0-Default)
The amount of time (in seconds) the lowest available fan speed will run after the
thermostat cooling outputs are disabled
