QUESTIONS
Remember, whichever way you set your thermostat, if it is so cold
outside that your house drops to your sleep temperature, the furnace
will turn on and off at night to control the temperature at that setting.
It bypasses all program settings and holds the temperature at the
present setting. To increase or decrease the temperature while on
HOLD, use the WARMER-COOLER keys. Touching RUN PROGRAM
will return the device to programmed operations.
Forever! The HOLD button will hold the temperature indefinitely. The
only way to release it is to push the RUN PROGRAM button or change
the system switch positions if applicable. For a temporary temperature
change, simply press WARMER or COOLER key. This temporary
setting will last until the next scheduled program begins.
Two ways. First, it saves energy (and money) by setting back the
temperature for blocks of time during the day or night. Second, it
conserves energy by recovering gradually to the desired temperature.
This prevents overshooting your comfort set point (and wasting energy)
or undershooting the comfort set point (and forcing you to change the
thermostat setting, also wasting energy).
