TB7100A1000 MULTIPRO™ MULTISPEED AND MULTIPURPOSE THERMOSTAT
3 62-0273—05
Fig. 5. Restrict wires to shaded area of wire hole.
Table 2. Terminal Designation Descriptions.
NOTES:
1. When used in a single-transformer system,
leave metal jumper wire in place between RC
and R. If used on a two-transformer system,
remove metal jumper wire between RC and R.
2. Common wire is optional when thermostat is
used with batteries. When using separate
transformers for heating and cooling, the
common must come from the cooling
transformer.
3. If thermostat is configured for a heat pump in
the Installer Setup, configure changeover
valve for cool (O-factory setting) or heat (B).
4. Sensor wires must have a cable separate
from the thermostat control cable.
