Year-Round Comfort.
Bryant’s ThermidistatTMControl provides enhanced, year-round comfort. By providing both
temperature and humidity control, this simple, yet powerful, device lets you take the steam out
of summer, the static out of winter and helps eliminate that annoying moisture build-up on
your windows when it’s cold outside. It’s never been quite this easy, and you’ve never had quite
this much comfort available through one control.
Simple, Convenient Control.
Bryant puts your family’s comfort at your fingertips with simple instructions, responsive
push buttons and an easy-to-read, lighted display. Once set, the thermidistat control accurately
monitors indoor conditions and reliably meets your desired comfort levels. Plus, you have the
convenience of temporarily bypassing your settings without disrupting your permanent
comfort schedule.
NOTE: Not all messages displayed in above illustration will appear at once in any situation.
MODE button selects OFF, HEAT,
COOL or AUTO operation.
EMERGENCY HEAT (EHEAT) mode
is also included when the
thermidistat control is installed
with a heat pump.
