Honeywell R829 FAN CENTER OR AT72H,J TRANS- FORMER (WTH APPROPRATE RELAY), PROVDES LOW VOLTAGE CONTROL OF LNE VOLTAGE FAN MOTORS AND AUX- LARY CRCUTS N HEATNG, COOLNG, OR HEATNG-COOLNG SYSTEMS.

1 Honeywell R829 FAN CENTER OR AT72H,J TRANS- FORMER (WTH APPROPRATE RELAY), PROVDES LOW VOLTAGE CONTROL OF LNE VOLTAGE FAN MOTORS AND AUX- LARY CRCUTS N HEATNG, COOLNG, OR HEATNG-COOLNG SYSTEMS. AT72H,J Transformer provides for addition of cooling at later date without expensive rewiring by simply plugging in an R8222 (/4 hp) or an R8228 ( hp) Switching Relay. Overload protection is provided for the transformer. Large 8 VA transformer to power heatingcooling low voltage control systems. Low voltage terminal board provides convenient connections for thermostat, and heating and cooling equipment control circuit wiring. o Mounts on standard 4 inch square junction box. Relay in R829 is mounted in a receptacle and can easily be replaced without disturbing wiring. R829, with completely enclosed relay, can be mounted in any indoor location without additional enclosure. Meets NEMA ST2-97 Standard Residential Controls-Class 2 Transformers, marked NEMA Type D.

Make wiring connections in the junction box; then fasten the fan center to the box, placing the junction box screws through notches in the fan center mounting plate. On receptacles without relays, select and mount the appropriate relay (Table ) and attach the relay cover. A label identifying the relay used (furnished with TRADE LNE models) should be applied to the relay cover. NOTE: Relay may be mounted in any position. With the terminals pointing down, pickup voltage is increased by 2 percent. WRNG All wiring must comply with local codes and ordinances.
