Informació de seguretat
ADVERTÈNCIA: Risc elèctric
- Desconnecteu sempre l'alimentació del sistema de calefacció/refrigeració al fusible principal o al quadre elèctric abans d'instal·lar o fer el manteniment del termòstat.
- Failure to do so may result in electrical shock, property damage, or death.
- Si no esteu segurs de cap pas, la instal·lació l'ha de dur a terme un tècnic qualificat.
Configuració i instal·lació
Eines necessàries:
- Tornavís (Phillips i cap pla)
- Pelafils/tallador
- Perforar (si calen nous forats de muntatge)
- Level (built-in on thermostat for convenience)
Llista de verificació prèvia a la instal·lació:
- Apagar: Disconnect power to your heating and cooling system at the main fuse or circuit breaker.
- Elimina el termòstat antic: Carefully remove the cover of your old thermostat. Take a picture of the wiring connections for reference.
- Etiqueta els cables: Label each wire with the terminal designation from your old thermostat (e.g., R, G, Y, W).
- Eliminar la base antiga: Unscrew and remove the old thermostat base from the wall.
Muntatge del nou termòstat:
- Separate Base: Gently pull the front of the new thermostat from its base.
- Base de posició: Hold the thermostat base against the wall where you want to install it. Use the built-in level to ensure it is straight.
- Marca els forats: Mark the mounting hole locations on the wall.
- Drill Holes (if needed): Drill pilot holes if mounting to drywall or plaster. Insert wall anchors if necessary.
- Base segura: Pull the thermostat wires through the opening in the base and secure the base to the wall using the provided screws.

Imatge: Part posterior view of an Emerson thermostat base showing the wiring terminals. This illustrates where the labeled wires from your HVAC system will connect.
Connexions de cablejat:
Refer to the wiring diagram specific to your HVAC system type. Connect the labeled wires to the corresponding terminals on the new thermostat base. Ensure all connections are secure.
- R/Rc/Rh: 24V AC power (often red wire).
- C: Common wire (provides continuous 24V power, often blue or black).
- S/S1: Heat call (often white wire).
- A/A1: Cool call (often yellow wire).
- G: Fan call (often green wire).
- O/B: Reversing valve for heat pumps.
- Aux/E: Auxiliary/Emergency heat for heat pumps.
Nota:
- The 1F83C-11NP is for conventional systems (1 Heat/1 Cool).
- The 1F83H-21PR is for heat pump systems (2 Heat/1 Cool with Aux/E).
- If your old thermostat had a 'C' wire, connect it. If not, the thermostat will operate on battery power, but the backlight may not stay on continuously.
Instal·lació de la bateria:
Insert two fresh AA alkaline batteries into the battery compartment on the back of the thermostat faceplate. Ensure correct polarity.
Attach Thermostat Faceplate:
Align the faceplate with the mounted base and gently push until it snaps securely into place.
Engegada i configuració inicial:
- Restaura l'alimentació: Turn power back on at the main fuse or circuit breaker.
- System Type Selection (Installer Menu): Access the installer menu to configure the thermostat for your specific HVAC system (conventional or heat pump, gas or electric furnace). Refer to the detailed installer manual for specific menu codes and settings.
- Set Time/Date (1F83H-21PR only): For the programmable model, set the current time and day.
