Fault Flash
When using a TA32W01 or TP32W02 thermostat and
SW2-8 is in the pulsing “L” position, FaultFlash will enable
a user to view the thermostat and count the fault indica-
tor flashes to determine the lockout condition the unit is
experiencing.
ComforTalk
When using a TP32U03, 04 or 05 thermostat and SW2-8
is in the pulsing “L” position, ComforTalk will enable the
user to view the thermostat and determine the fault. The
thermostat can be configured to show either lockout text
or lockout codes.
The LED board on the front of the unit will display all
lockouts. The Low Pressure LED will flash for a low pres-
sure condition or a Comfort Alert fault. If the low pressure
lockout was caused by Comfort Alert codes 4, 6 or 7, then
the Comfort Alert will be flashing. If no Comfort Alert code
is visible, then it is a low pressure lockout.
