Note: If the thermostat is set to utilize a time-based purge
cycle (Service menu 16), the thermostat will conduct
a 3-min purge on initial start-up if a pipe sensor is
connected.
Condensate Overflow Interrupt
The remote probe input can be used with a condensate
overflow interrupt switch (CO), either in conjunction with a
remote probe (normally closed CO switch) or with local
sensing (normally open CO switch). When the condensate
switch activates, the T180 will display the service wrench and
disable all outputs.
