RC/RH jumper:
Most HVAC systems build-in a common heating and cooling transformer. The ZTS-500

has a built-in RH/RC jumper wire to connect RH and RC inputs for this configuration.
If the HVAC system contains separated heating and cooling transformers, please cut out

the RH/RC jumper and then connect the RC and RH inputs individually.
Thermostat wiring:
For Non-Heat Pump HVAC systems, please refer to figure 7,

For Heat Pump HVAC systems, please refer to figure 10, 11, and 12.
