Fol- low all local electrical codes during installation. All wiring must conform to local and national electrical codes. Improper wiring or installation may damage the thermostat. Recognize safety information. This is the safety alert sym- bol . When the safety alert symbol is present on equipment or in the instruction manual, be alert to the potential for person- al injury. Understand the signal words DANGER, WARNING, and CAUTION. These words are used with the safety alert symbol. DANGER identifies the most serious hazards which will result in severe personal injury or death. WARNING signifies a haz- ard which could result in personal injury or death. CAUTION is used to identify unsafe practices which would result in minor personal injury or property damage. GENERAL Totaline® 7-day, programmable thermostats are wall-mount- ed, low-voltage thermostats which maintain room temperature by controlling the operation of an HVAC (heating, ventilation, and air-conditioning) system. Separate heating and cooling set points and auto-changeover capability allow occupied and un- occupied programming for energy savings. All programmable thermostats allow up to 4 time/tempera- ture settings to be programmed per 24-hr period. Each thermo- stat stores programs for 7 independent days. Batteries are not required. During power interruption, the internal memory stores comfort schedules for an unlimited time while the clock continues to run for at least 72 hours. INSTALLATION CONSIDERATIONS Models — There are 3 different models. Ensure the proper thermostat is selected for the intended application. Refer to Fig. 1 for thermostat dimensions. Select from the following models: 1. P274-1100 (air conditioner [AC]) — 1-stage cool, 1-stage heat for air-conditioning systems only 2. P274-1200 (heat pump [HP]) — 1-stage cool, 2-stage heat for either heat pump or air conditioner systems with 2-stage heat 3. P274-1300 (2-speed) — 2-stage cool, 2-stage heat for 2-speed AC systems, or 2-stage cool, 3-stage heat for 2-speed HP systems, or 1-stage cool, 4-stage heat for 1-speed HP with special 3-stage electric heat Outdoor Temperature Sensing — All programma- ble thermostats can be equipped with an optional outdoor tem- perature sensor, part no. TSTATXXSEN01-B. If this option is to be installed, plan thermostat installation so that 2 wires can be run from the thermostat to an outdoor location. Refer to the installation instructions provided with the outdoor temperature sensor for necessary connections. IMPORTANT: Read entire instructions before start- ing the installation.
