5. OPERATION
The Model LS-HC Limit-Stat™ operates like an ordinary
manual changeover heating/cooling, digital thermostat.
In normal operation, it allows full user control in selecting
mode (HEAT/COOL) and fan (ON/AUTO) as well as
adjustment of heating and cooling setpoints. However,
when the thermostat is in the heating mode of operation,
the built-in limiter will prevent the temperature from rising
above 73° F when the setpoint is adjusted above the
limit range. This unique feature greatly reduces energy
costs.
LIMITER
RED jumper wire (provided with thermostat)
must be connected between thermostat RH
