Troubleshooting
Problem Potential Cause Potential Solution
HVAC unit does not operate.
Main electrical failure to the unit.
Many units operate on 230 or 277VAC
circuits, so although power is available
to the 110VAC plugs in the room, the
branch circuit supplying HVAC power
may be interrupted.
Dispatch maintenance. Verify mains
continuity to the unit.
GFI within the HVAC has tripped. Some
models of HVAC systems (often
PTAC/PTHP units) contain integral GFI
(Ground-Fault Interrupt) systems.
Occasionally, often after a power
outage, inrush current when power
returns can cause GFIs to trip. Most
times, this does not indicate issues
with the unit.
Check and reset units’ GFI systems.
EcoSource has failed.
Replace the EcoSource with a known-
good unit as a comparison-check.
If the replacement unit functions
properly, contact Telkonet and begin
the RMA process.
If the replacement unit does not
function properly, consult a local HVAC
technician to inspect your HVAC unit.
Door contact is not connected.
Ensure that all door contacts are
connected.
Window or outside door is open.
Ensure that no monitored windows or
patio doors are open.
