Follow all local electrical codes during installation. All wiring must conform to local and national electrical codes. Improper wiring or installation may damage AC/HP Control. Recognize safety information. This is the safety.alert symbol . When you see this symbol on the equipment and in the instruction manual, be alert to the potential for personal 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 hazard which could result in personal injury or death. CAUTION is used to identify unsafe practices which may result in minor personal injury or product and property damage. NOTE is used to highlight suggestions which will result in enhanced installation, reliability, or operation. 1 INTRODUCTION Carrier’s 7.day, 5/2.day, 1.day programmable and non.programmable Performance Series Thermostat Control is a wall.mounted, low.voltage temperature control in either a single unit or a two.piece unit. In two.piece configuration, the relays are located near the equipment and a two.wire connection is used between the Display Module and the Equipment Control Module. Single.piece installation requires more wiring and results in a higher profile. The Edge Thermostat has no need for batteries to store user.configured settings in memory. During power loss its internal memory saves settings for unlimited time, and the clock continues to run for at least 24 hours. An extension of Carrier’s proven line of thermostats; it provides separate setpoints for heating and cooling. In the Edge Thermostat Control programmable configuration, different heating and cooling setpoints and times are programmable for 4 periods per day or 2 periods per day. Programming can be done for 7 days per week, 5/2 days per week, or 1 day. The programmable Thermostat Control can also be user configured as a non.programmable Thermostat Control. The non.programmable Thermostat Control features Touch ’N’ Go settings for quick and easy temperature change without complicated programming schedules. And, its Touch ’N’ Go technology enables the user to switch between three different user.configurable settings through intuitive buttons located just below the display. 2 INSTALLATION CONSIDERATIONS Power This control is powered by 24VAC only. It requires 24VAC (Rh and/or Rc and C terminals) of the low.voltage transformer to be connected to it for proper operation. It will not operate without these 2 connections. Rh and Rc are connected via PCB breakout jumper. See Fig. 1. For applications using two 24VAC transformers, one in the indoor unit and one in the outdoor unit, connect the common from each to the C terminal. Connect R from the indoor unit to the Rh terminal. Connect R from the outdoor unit to the Rc terminal. Then, break jumper on the circuit board. The W signal is taken from the Rh power and the G signal is taken from the Rc power. If the thermostat has been installed in a two.transformer application that is later changed to a single.transformer installation, installer must install a field supplied jumper between Rc and Rh. Depending on the installation, up to 14 wires may be required. Installation as two.piece unit is recommended. Only 2 wires are required for connection between Display Module and Equipment Control Module. These two wires (V+ and Vg) do not provide ordinary 24VAC. They carry a combination of power and communications data that is unique to these products. 3 A07052 Fig. 1 . PCB Breakout Jumper Models There are programmable and non.programmable models for all applications. They can be configured for AC or HP installations, allowing it to be used in place of all Carrier thermostats. Programmable thermostats may be configured as non.programmable if user desires. Outdoor Temperature Sensor The outdoor air temperature sensor is not included ...
