E110
Low line voltage.
Line Voltage Low (Voltage lower than nameplate rating). Check power
line voltage and correct. Alarm clears 5 seconds after fault recovered.
E111
Line voltage polarity reversed.
Reverse line power voltage wiring. System resumes normal operation
5 seconds after fault recovered.
E112
Ground not detected.
System shuts down. Provide proper earth ground. System resumes
normal operation 5 seconds after fault recovered.
E113
High line voltage.
Line Voltage High (Voltage higher than nameplate rating). Provide
power voltage within proper range. System resumes normal operation
5 seconds after fault recovered.
E114
Line voltage frequency out-of-range.
No 60 Hertz Power. Check voltage and line power frequency. Correct
voltage and frequency problems. System resumes normal operation 5
seconds after fault recovered.
E115
Low 24V - Control will restart if the error
recovers.
24-Volt Power Low (Range is 18 to 30 volts). Check and correct
voltage. Check for additional power-robbing equipment connected
to system. May require installation of larger VA transformer to be
installed in furnace / air handler. Clears after fault recovered.
E117
Poor ground detected (Warning only).
Provide proper grounding for unit. Check for proper earth ground to
the system. Warning only will clear 30 seconds after fault recovered.
