E110 Low line voltage.
E111 Line voltage polarity reversed.
E112 Ground not detected.
E113 High line voltage.
E114 Line voltage frequency out-of-range.
E115 Low 24V - Control will restart if the error recovers. 24 Volt Power high (Range is 18 to 30 Volts). Check
E116 High 24V.
E117 Poor ground detected (Warning only).
E126 Control internal communication problem.
Action Required to Clear and Recover
Line Voltage low (Voltage tower than nameplate rating).
Check power line voltage and correct. Alarm clears 5
seconds after fault recovered.
Reverse line power voltage wiring. System resumes
normal operation 5 seconds after fault recovered.
System shuts down. Provide proper earth ground.
System resumes normal operation 5 seconds after fault
recovered.
Line Voltage high (Voltage higher than nameplate
rating). Provide power voltage within proper range.
System resumes normal operation 5 seconds after fault
recovered.
No 60 Hertz power. Check voltage and line power
frequency. Correct voltage and frequency problems.
System resumes normal operation 5 seconds after fault
recovered.
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.
24 Volt Power high (Range is 18 to 30 Volts) Check and
correct voltage. Check for proper line voltage (120V
240V etc) to equipment. Clears when control senses
proper voltage.
Provide proper grounding for unit. Check for proper
earth ground to the system. Warming only will clear 30
seconds after fault recovered.
Hardware problem on the control. Cycle power on
control. Replace if problem prevents service and is
persistent. Cleared 300 seconds after fault recovered.
