THERMOSTATS--SOME TYPICAL WIRING DIAGRAMS:
- Heating-only circuit in continuous pilot gas
or central electric system
- Heating-only circuit in an oil system.
- Heating/cooling circuit in a single transformer
system with electric heat/electric cooling
and changeover terminals (O, B). Thermostat controls fan in heat and
cool (typical single-speed fan applications).
- Heating/cooling circuit in an oil heating/electric
cooling system with changeover terminals (O, B). Heating transformer
is in oil primary.
- Heating/cooling circuit in a two-transformer
(one for heating, one for cooling) system with gas heat/electric
cooling, RC and R terminals.
- Heating/cooling circuit for a single-stage
electric heat pump. Fan controlled by thermostat.
- Heating/cooling circuit in a single transformer
system with gas heat/electric cooling.
- Heating/cooling circuit for a single-stage
electric heat pump with changeover terminals (O, B).
- Heating/cooling circuit in a single transformer
system with gas heat/electric cooling or electric heat/electric cooling
and changeover terminals (O, B). Thermostat controls fan in cooling
only (typical multi speed fan applications).
- Conversion of 125 Vac Control System to 24 Vac controls to allow for use of NEW DIGITAL PROGRAMMABLE THERMOSTATS.
