Troubleshooting
Problem
Potential Cause
Potential Solution
Touch screen performance issues.
Noisy supply voltage can interfere with
E functionality.
Tie the 12V DC ground to the JBOX
ground.
MAC Address reverting to FFFF during
installation
May be caused by wire-nutting the
power connections to the E
to a "live" or "energized" power
source.
De-energize power from the circuit
prior to making an electrical
connection to the E.
Room does not achieve setpoint within
RecoveryTime.
The most common cause is that the
EcoSmart system is designed to recover
the temperature within a Comfort
Zone. The Comfort Zone is
programmable by Telkonet, and is
chosen by management before
installation.
The thermostat may be programmed
with settings not appropriate to the
specific deployment scenario.
Contact Telkonet Customer Support.
Telkonet will research the deployment
history, and determine whether a
completed Settings Sheet was provided
to us prior to thermostat shipment.
Note that Professional Services fees
may apply if a reported anomaly is
later determined to have been caused
by default settings when specific
preferences were not communicated to
Telkonet prior to device shipment.
Often an HVAC unit is in need of
servicing. For example, a unit with a
failing compressor or under-charged
refrigerant may not be able to
efficiently return the room to the
occupants’ desired setpoint.
Ensure the PTAC unit is in good working
order.
Service and correct internal thermostat
anomalies per PTAC manufacturer’s
recommended best practices.
There may be a failed control circuit
within the HVAC system
Ensure the PTAC unit is in good working
order.
Service and correct internal thermostat
anomalies per PTAC manufacturer’s

be able to achieve a setpoint of 60°.
Ensure the PTAC unit is in good working
order.
Service and correct internal thermostat
