TB7100A1000 MultiPRO™
Multispeed and Multipurpose Thermostat
FOR CONVENTIONAL, HEAT PUMP, FAN COIL AND PTAC SYSTEMS
APPLICATION
The TB7100A1000 MultiPRO™ Multispeed and Multipurpose
Thermostat is an effortless, seven-day programmable or non-
programmable thermostat that provides universal system
compatibility, precise comfort control and is easy-to-program.
The TB7100 provides temperature control for gas, oil, electric,
heat pumps, PTACs, and fan coil equipment for the following
types of applications:
— 1H/1C conventional
— Up to 2H/1C heat pump
— 4 pipe fan coil (3 fan speeds)
— 2 pipe fan coil (3 fan speeds)
— 2 pipe fan coil with Auxiliary Heat (3 fan speeds)
— PTAC (Hi, Lo fan speed)
FEATURES
• Large, clear display with backlight shows the current
and set temperature and time—even in the dark.
• Menu-driven programming make setup effortless.
• Beautiful ergonomic design is smart and sophisticated
to match your customers' lifestyle.
• Real-time clock keeps time during power failures and
