SETTING THE THERMOSTAT
This thermostat is very easy to operate. Set the SYSTEM
switch to either HEAT or COOL then press
the temperature you want to maintain is shown on the right side
of the display. If you want to turn the system off, just move the
SYSTEM switch to OFF.
The FAN switch controls the fan operation. When the FAN
switch is set to AUTO, the fan will cycle with the furnace or air
conditioner. When the FAN switch is set to ON, the fan will run
continuously, regardless of SYSTEM switch position.
Corrective Action
Replace fuse or reset breaker.
Turn switch to ON.
Replace door panel in proper position to engage safety interlock or
door switch.
Set System Switch to Heat and raise setpoint above room
temperature.
Verify thermostat and system wires are securely attached.
Diagnostic: Set System Switch to Heat and raise the setpoint
above room temperature. Within five minutes the thermostat
should make a soft click sound. This sound usually indicates the
thermostat is operating properly. If the thermostat does not click,
try the reset operation listed above. If the thermostat does not click
after being reset contact your heating and cooling service person
or place of purchase for a replacement. If the thermostat clicks,
contact the furnace manufacturer or a service person to verify the
heating system is operating properly.
Set System Switch to Cool and lower setpoint below room
temperature.
Verify thermostat and system wires are securely attached.
Same procedure as diagnostic for No Heat condition except set
the thermostat to Cool and lower the setpoint below the room
temperature. There may be up to a five minute delay before the
thermostat clicks in Cooling if the compressor lock-out option is
selected in the configuration menu (Item 6).
Check each wire connection to verify they are not shorted or
touching together. No bare wire should stick out from under
terminal screws. Try resetting the thermostat as described above. If
the condition persists, the manufacturer of your system or service
person can instruct you on how to test the Heat/Cool system for
correct operation. If the system operates correctly, replace the
thermostat.
Item 2 in the Configuration Menu is the adjustment that controls
the cycle rate. If an acceptable cycle rate is not achieved using the
FA (Fast) or SL (Slow) adjustment contact a local service person
for additional suggestions.
The cycle rate for cooling is fixed and can not be adjusted. Contact
a local service person for suggestions.
The thermometer can be adjusted +/- 4 degrees as listed in item 7
of the Configuration Menu. No other adjustment is possible.
Check heat/cool system for power.
If a voltage spike or static discharge occurs use the Reset
Operation listed above.
