previous flash code until the condition returns to normal or
24VAC is removed from the module. TRIP and ALERT
LEDs flashing at the same time means control circuit
voltage is too low for operation.
previous flash code until the condition returns to normal or
24VAC is removed from the module. TRIP and ALERT
LEDs flashing at the same time means control circuit
voltage is too low for operation.
24VAC Power Wiring
The diagnostic module requires a constant nominal
24VAC power supply. The wiring to the module’s R and C
terminals must be directly from the indoor unit or thermo-
stat. The module cannot be powered by R and C terminals
on the defrost board without experiencing nuisance alerts.
