PANEL 3 Required Accessories Not Supplied Rating VA for static pressure Mount the TZ 4 zone panel near the HVAC equipment a wall or on the cold air return See Fig 2 Level the TZ 4 for appearance only Hazard cause electrical shock or equipment damage power before continuing installation must comply with applicable codes ordinances and Connect thermostats as shown in Fig 3 6 Connect dampers as shown in Fig 7 10 Connect C7735A Discharge Air Temperature Sensor supplied to the DATS terminals The wires are not See Fig 13 Connect Add A Zone panels if used to the AZ1 and terminals Connect the HVAC equipment to the EQUIP terminals the panel See Fig 15 21 Connect a 40 VA 24 volt transformer to R hot and C This must be a dedicated transformer and TAZ 4 board also requires a transformer See Fig The auxiliary 40 VA 24 volt transformer can be con to T1 and T2 if additional power for dampers is This second transformer is not required how total power consumption of panel and damper is to 40VA

TZ 4 mounting location Diagrams Fig 3 and 4 Thermostats RWYG thermostats can be used to control multi stage and heat pump equipment If the has a common terminal it is wired to C on the see Fig 3 A multi stage thermostat is wired with the and third stage of heat to W2 and W3 on the panel connections and with the second stage of cooling Y2 Leave the zone O B thermostat jumper on the TZ 4 See Single and Multi Stage Operation in the section for instructions on staging the TZ 4 PC8900 with the W8900A or W8900C can be used as a thermostat See Fig 4 for hookup This thermostat can used to control up to 2 heat and 2 cool stages of equipment When used to control heat pump the W8900A is recommended a jumper on the W8900 from Rc to Rh as shown in 4 Wire terminals R and C to a transformer
