WARNING!
Hazardous Voltage!
Disconnect all electric power,
including remote disconnects before
servicing. Follow proper lockout/
tagout procedures to ensure the
power can not be inadvertently
energized. Failure to disconnect
power before servicing could result
in death or serious injury.
Temperature Limiter
The temperature limiting feature can
reduce energy costs by controlling
the maximum temperature available
in heating and the minimum
temperature available in cooling.
Temperature Limiting
The temperature limits are set by
configuring the DIP switch bank at
the lower right hand corner of the
control board to the proper settings.
These settings will depend on the
owner preference. Below is a table
showing the DIP switch settings and
their respective temperature limits.
To expose the DIP switch bank,
remove the front cabinet (see
Disassembly Instructions) and locate
the control board. The DIP switch
bank should be visible along with
the remote thermostat terminals
without having to remove anything
else.
