Front Panel Components
Message Display
Two types of messages are displayed, Permanent and Temporary Messages. Permanent Messages
are those that scroll continually during thermostat operation. Temporary (flashing) Messages are
intended to catch your eye and must be reset to be removed from the display. Thermostats are
shipped with default (permanent) status messages (i.e. mode status, fan status, equipment status).
Scroll/Set-up buttons
The Scroll/Set-Up buttons function with the set-up features of the thermostat (refer to the Set Up
and Configuration section on page 45 for details).
Mode button
Five modes of operation are available on the ViewStat thermostat:
 OFF
 COOL
 AUTO
 HEAT
 EM. HEAT (for heat pumps only)
The mode of operation indicates how you want your heating and cooling equipment to operate.
