PRESTIGE THERMOSTATS CAN BE POWERED BY ANY TRANSFORMER. IN THIS EXAMPLE THEY ARE POWERED BY
THE SAME TRANSFORMER THAT POWERS THE HZ432.
THERE CAN BE UP TO 4 PRESTIGE THERMOSTATS USED WITH A SINGLE THM4000R WIRELESS ADAPTER AND HZ432
ZONE PANEL. THE THM4000R CANNOT BE USED IF THERE ARE MORE THAN 4 ZONES IN THE SYSTEM.
RH/RC JUMPER INSTALLED WHEN SINGLE HEAT/COOL TRANSFORMER IS USED.
DOTTED LINES APPLY ONLY TO MULTI-STAGE EQUIPMENT. SEE HZ432 INSTALLATION INSTRUCTIONS FOR
HEAT PUMP WIRING.
A THM4000R CANNOT BE USED WITH THE PRESTIGE THERMOSTAT IF THE THERMOSTAT IS CONTROLLING HUMIDIFICATION,
DEHUMIDIFICATION, OR VENTILATION.
