When installing in a singletransformer system, keep the jumper wire between the Rand Rc screws. When installing in a two-transformersystem, use the common from the cooling transformer toconnect to the B screw and remove the jumper wirebetween the R and Rc screws.Three AAA alkaline batteries can be used to power thecomfort control for armchair programming only. To preventthe comfort control and heating/cooling system fromshutting down due to lack of battery power, it is notrecommended that the comfort control be solely poweredwith the three AAA batteries during normal systemoperation. When using batteries, make sure positive andnegative terminals are oriented correctly, as marked onthe device. See Fig. 16.Battery Power (Optional)CAUTIONEquipment or Property Damage Hazard.Using battery power only may not provideadequate power to comfort control and cancause damage during freezing conditions.Connect the 24 Vac Common (B) wire from thesystem transformer to the comfort control forproper operation when the battery power isdrained.BATTERIES (3)M19918Fig. 16.
