ERROR CODES
• Check wiring at the terminal block to conrm the reversing valve is connected to the proper terminal. O is active in cooling and B
is active in heating.
• Check SW1 (Equipment Type), to make sure it is set to match the installed heating/cooling equipment (see page 8).
• Check to make sure heating and cooling wires are not shorted together.
• Check SW1 (Equipment Type), to make sure it is set to match the installed heating/cooling equipment (see page 8).
• Check Installer System Setting number 05 (Control Setup) is set correctly.
• Change the System Mode to Heat, and set the temperature level above the current room temperature.
• Check Installer System Setting number 05 (Control Setup) is set correctly.
• Change the System Mode to Cool, and set the temperature level below the current room temperature.
• From TPT touchscreens: If the thermostat is in Heat mode it is possible to change the COOL setpoint lower than the heat
setpoint, when the thermostat is changed to Cool mode, the HEAT setpoint will be pushed to the thermostat causing the COOL
setpoint to move 3 degrees above the HEAT setpoint.
• The HEAT setpoint always takes precedence over the COOL setpoint. The only exception is while in Auto mode, if the COOL
setpoint is pushed below the HEAT setpoint, the HEAT setpoint is pushed 3 degrees lower than the COOL setpoint and vice-
versa.
• Other changes to the thermostat while in Network Override or OFF are also updated when moving out of either of these modes.
The only exception is the FAN control mode which executes in any mode.
If the thermostat enters an error mode, all outputs are turned off. The thermostat attempts to recover every 10 minutes. If the error
does not clear, use the reset* button. This will return all settings back to factory default.
*CAUTION: Thermostat power must be cycled after a reset for the CC-WLINT or CC-RLINT stations to operate correctly.
