Troubleshooting
Power Loss
The H
ō
M™ Energy Manager thermostat is designed to withstand a power loss without the need of a battery backup. The
thermostat responds to a power loss as follows:
•
All Thermostat Settings and Schedule Programming are stored to permanent memory and retained throughout the power loss.
•
The thermostat will return to the same System Mode (Off/Heat/Cool/Aux) it was in prior to the power loss.
•
A
Permanent Hold
will be maintained after a power loss.
•
A
Temporary Hold
will be maintained after a power loss ONLY if still within the same Program Schedule time period.
Otherwise the thermostat will return to operating according to the Program Schedule.
•
The thermostat is designed to maintain the clock for at least 24 hours without power. If power has been lost for more than
24 hours, the clock will return to a factory default time and will update with the next utility time sync.
•
A
Conservation Period
will be maintained after a power loss if still within the same conservation period.
