Bryant 550A Specifications page 22

* Tested combination.
† In most cases, only one method should be used to achieve TDR function. Using more than one method in a system may cause degradation in performance.
Use either the accessory Time-Delay Relay KAATD0101TDR or a furnace equipped with TDR. Most Bryant furnaces are equipped with TDR.
‡ TXV must be Puron compatible and hard shutoff type.
EER — Energy Efficiency Ratio
LLS — Liquid-Line Solenoid Valve
SEER — Seasonal Energy Efficiency Ratio
TDR — Time-Delay Relay
TXV — Thermostatic Expansion Valve
NOTES: 1. Ratings are net values reflecting the effects of circulating fan motor heat. Supplemental electric heat is not included.
2. Tested outdoor/indoor combinations have been tested in accordance with DOE test procedures for electric air conditioners. Ratings for other com-
binations are determined under DOE computer simulation procedures.
3. Determine actual CFM values obtainable for your system by referring to fan performance data in fan coil or furnace coil literature.
4. Do not apply with capillary tube coils as performance and reliability are significantly affected.
