No. Representative Notes APPLICATION Model HZ221K: Kit includes HZ221 zone panel, C7735A1000 discharge sensor, and AT140A1042 40 VA transformer. 2 zones and 2H/1C heat pump with auxiliary electric heat only. SPECIFICATIONS Input Ratings: Voltage: 18-30 VAC 50/60 Hz transformer of 40 VA or more. Current Draw: Zone Panel: 6.25 VA max. All VA specifications at 24 VAC. Wiring: 18-gauge solid (not stranded) wire. Mounting Means: The HZ221 has mounting holes on the sides top and bottom so it can be mounted on a wall, return duct, or stud. Humidity Ratings: 5% to 90% RH non-condensing. Temperature Ratings: Shipping: -20° to 150°F (-29° to 66°C). Operating: -40° to 165°F (-40° to 74°C). Emissions: Complies with FCC Class B, part 15 requirements. HZ221 TrueZONE Panel Dimensions in Inches (mm): Model(s) HZ221K Qty. Approval Service Tag No. SUBMITTAL SHEET Notes Maximum Dampers Per Zone (Size Transformer Appropriately): Max temperature in zone panel location Maximum VA per zone * 100°F (38°C) 28.8 VA 160°F (71°C) 16.8 VA 6.5 VA for HZ221 zone panel. 8 VA per ARD series zone damper. 8 VA per ZD series zone damper. 2.5 VA per MARD series zone damper. 2.5 VA per RRD series zone damper. * If exceeding max VA per zone, use SDCR relay to isolate a zone from panel. Separate SDCR required for each zone exceeding max VA. Honeywell Zone Dampers for use with HZ221K: Damper Sizes ZD series (rectangular) Even sizes from 6" x 6" up to 28" x 20" ARD series (round) 5-10" in 1" increments, 12-18" in 2" increments. MARD series (round) 5, 6, 8, 9, 10, 12, 14, 16, and 18" models. RRD series (retrofit) 5, 6, 7 and 8" models. VA per damper (max) 8 VA 8 VA 2.5 VA 2.5 VA Accessories: Model number Description AT140A1042 40 VA transformer (included in HZ311K (kit)). AT175A1058 75 VA transformer. C7735A1000 Discharge Sensor (included in HZ311K (kit)). SDCR Slave Damper Control Relay. Needed when there are too many dampers for a zone. Thermostats HZ221K is only compatible with heat pump thermostats that use a cool changeover valve terminal (O).
