HZ432 TrueZONE Mounting 1 Mount the HZ432 TrueZONE panel near the HVAC equipment; locate it on a wall, stud, roof truss, or coldair return. NOTE: The HZ432 TrueZONE panel can be mounted in any orientation; level it for appearance only.
Installation Guide Wiring CAUTION: Voltage Hazard. Can cause electrical shock or equipment damage. Disconnect power before beginning installation. Wire entire panel before applying transformer power. Follow these steps for wiring all systems. However, wiring will vary depending on equipment. For conventional systems, refer to this page. For heat pump systems, see pages 6 and 7. For dual fuel systems, see pages 8 and 9. 3 Install thermostats using instructions provided with thermostats.
HZ432 TrueZONE 5 SENSOR Wiring Connect DATS as shown. DATS DATS M24804 C7735A1000 6 Connect equipment as shown. The DS/BK terminal is used with a variable-speed fan. Connect the DS, BK, ODD, or DHUM terminal on the HVAC equipment to this terminal. When 1 zone is calling (or 25% on systems with more than 4 zones) this terminal will be de-energized of 24 VAC. This reduces blower speed on most variable speed blowers. HVAC 24 VOLT TRANS.
Installation Guide Heat Pump Use the following diagram for wiring a 2-heat/1-cool heat pump with electric auxiliary heat. NOTE: You can use a conventional thermostat for a heat pump system; however, em heat can only be controlled by heat pump thermostats.
