Note: If continuous backlight or hardwired power input are desired but do not function in both HEAT and COOL modes, cut the heating transformer 24V wires and tape off. Connect the neutral circuit disconnected from the heating transformer to the neutral circuit of the cooling transformer. Disconnect the wire to the RH terminal and install a jumper between RH and RC. Depending on the system requirements, replace the cooling transformer with a 75VA class II transformer if needed.

Nota: si desea iluminación constante de la luz de fondo o alimentación de entrada con cableado interno pero no desea que el sistema funcione en los modos HEAT y COOL, corte los cables de 24 V del transformador de calefacción y encíntelos. Conecte el circuito neutro desconectado del transformador de calefacción al circuito neutro del transformador de enfriamiento. Desconecte el cable a la terminal RH e instale un puente entre RH y RC. Según los requisitos del sistema, cambie el transformador de enfriamiento por un transformador de 75 VA clase II si es necesario.
