ENERGY EFFICIENT CONTROL
Using the programmable or remote control features of your
thermostat, you can save energy costs by setting back the thermostat
during unoccupied times. This reduces the energy loss from indoors
to outdoors. In the past, it has been said that heat pumps should not
be set back because it takes more energy to re-heat the premises than
to keep it at the same temperature. This is true with mechanical
thermostats, because they will use the inefficient auxiliary heat to
recover from the setback. This is not true with the RC-101, because
it uses intelligence to ensure that recovery from setback is done using
the heat pump, and not the auxiliary heat. Because the heat pump
takes longer to recover, heat pumps should not be set back for periods
of time less than 4 to 6 hours.
The RC-101 has microprocessor intelligence that continually
monitors the performance of the heat pump and uses the auxiliary
heat only when necessary. If the RC-101 determines that the heat
pump is able to heat at a rate of 5 degrees per hour or better, the
auxiliary heat will not be used. If the heat pump is unable to heat at
this rate, the RC-101 will use the auxiliary heat to supplement that of
the heat pump. Under these conditions, the heat pump will run
continuously and the auxiliary heat will cycle on and off as needed.
If you wish to temporarily override Energy Efficient Control to heat
as quickly as possible, press the Hold key. The RC-101 will use the
Auxiliary Heat as needed to reach the heat setting, then resume
Energy Efficient Control once the setting is reached.
Remember to turn Hold off to resume programmed operation.
