INSTALLATION MOUNTING 1. Separate the zone panel cover from the base. See FIGURE 3. FIGURE 3 FIGURE 4 – MOUNTING HOLE LOCATIONS 2. Use the base as a template to drill mounting holes. See FIGURE 4 for mounting hole locations. USE TWO SCREWS WHEN ATTACHING TO A WALL STUD ZONE CONTROL USE FOUR SCREWS WHEN ATTACHING TO DRYWALL/PLASTER 3. Attach the base to an interior wall, stud or return duct. 2 1 90-2110 90-2470 INSTALLATION LOCATION RECOMMENDATIONS 1. Mount the zone panel near the HVAC equipment.
WIRING WARNING FIGURE 6 – WIRE TIE MOUNTS 120 volts may cause serious injury from electrical shock. Sudden operation may cause serious injury from moving parts. Leave power disconnected until installation is complete. Follow these steps for all system connections. Wiring will vary depending on equipment. Wiring of the zone panel must comply with applicable codes, ordinances and regulations. WIRE TIE MOUNTS • Use only 18 or 20 gauge solid (non-stranded) wire.
SELECT AND WIRE THE TRANSFORMER TO THE CONTROL PANEL 3. Sizing of transformer to accommodate the number of dampers: TRANSFORMER 24 VAC 2. Wire 24VAC from transformer to the POWER, R and C terminals (see FIGURE 7). FIGURE 7 – TRANSFORMER 120 VAC 1. Note: The HVAC equipment transformer cannot be used for power. A separate transformer should be used to power the zone panel, thermostats and dampers. a. Select your damper type. 90-2116 OPTION 1: Normally Open/Power Close Dampers (2-Wire) i.
ZONE DAMPER WIRING • Run 2-conductor thermostat wire for spring return dampers (normally open or normally closed). FIGURE 8 – NORMALLY OPEN / POWER CLOSE DAMPERS • Run 3-conductor thermostat wire for power open/power close dampers. • Multiple dampers for the same zone can be wired in parallel as shown in FIGURES 8 & 9. • Wire the dampers to the zone panel: –– NC – This terminal is used to power open a normally closed damper.
DISCHARGE AIR TEMPERATURE SENSOR (INCLUDED) • Wire the discharge air temperature sensor Model 8052 to the “DAT” terminals as shown. See FIGURE 10. FIGURE 10 – DISCHARGE AIR TEMPERATURE SENSOR • Maximum distance of the sensor from the zone panel is 300 feet. • Do not wire along 120VAC lines. • Refer to FIGURE 5 on page 5 for the proper mounting location of the discharge air temperature sensor.
SEQUENCE OF OPERATION The 6303/6302 zone panel is for single stage heat pump applications, with a single stage of auxiliary heat. The zone panel is a heat call priority system with automatic heating/cooling changeover after 20 minutes of operation. If two opposing (heating/cooling) thermostat calls exist while the system is idle, the heating call will be satisfied first. A heat pump thermostat is required in each zone.
