INTRODUCTION Carrier’s PTAC Comfortt Series non- --programmable thermostat is a wall- --mounted, low- --voltage thermostat which maintains room temperature by controlling the operation of a heating and/or air conditioning system. Both heat pump and air conditioner models are available. A variety of features are provided including battery operation, memory in case of power interruption, separate heating and cooling setpoints, backlighting, and built- --in installer test. This Installation Instruction guide and owners manual covers installation, configuration, start up and operation of the PTAC specific Comfort Series line of thermostats. INSTALLATION CONSIDERATIONS Models There are two models for the PTAC Comfort Series non- --programmable thermostat, AC and HP versions. The model PTACSTAT- --NP- --HC- --x is designed for AC systems, controlling one stage of cooling and one stage of heating. It will not operate a heat pump. Model PTACSTAT- --NP- --HP- --x is designed for HP systems, controlling one stage of cooling and two stages of heating. The HP thermostat model can be converted to an AC unit. Select the appropriate model for the intended application. Power All Comfort Series models are dual powered. They can operate from batteries (optional) or 24VAC power. Operation from 24VAC is preferred, if available. 4 Batteries Battery operation is available for installations where there is no common (C) wire available at the thermostat. For battery operation, install two alkaline AA batteries. The thermostat is designed to operate up to one year on a set of batteries. A battery indicator on the display warns when battery replacement is needed. If batteries are installed and the thermostat is operated from 24VAC power, battery operation will occur only when 24VAC power is not present. The changeover between 24VAC power and battery power is automatic. For HeatCool system, 5 wires are needed for 24VAC operation and 4 wires are required for battery operation. For HP system, 6 wires are needed for 24VAC operation and 5 wires for battery operation. When battery operation is used, the C terminal does not need to be connected. NOTE: Batteries are not required when there are enough wires for proper operation. INSTALLATION Mounting to a horizontal junction box. For those installations requiring it, mounting hole locations for the non- --programmable are spaced to fit a horizontal junction box. Step 1 — Thermostat Location S Approximately 5 ft (1.5m) from floor. S Close to or in a frequently used room, preferably on an inside partitioning wall. S On a section of wall without pipes or duct work. 5 Thermostat should NOT be mounted S Close to a window, on an outside wall, or next to a door leading to the outside. S Exposed to direct light or heat from the sun, a lamp, fireplace, or other temperature- -- radiating objects which could cause a false reading. S Close to or in direct airflow from the unit. S In areas with poor air circulation, such as behind a door or in an alcove. Step 2 — Install Thermostat ! WARNING ELECTRICAL OPERATION HAZARD Failure to follow this warning could result in personal injury or death. Before installing thermostat, turn off all power to equipment. There may be more than 1 power disconnect. Lock out and tag switch with a suitable warning label. 1. Turn OFF all power to unit. 2. If an existing thermostat is being replaced: a. Remove existing thermostat from wall. b. Disconnect wires from existing thermostat, 1 at a time. Be careful not to allow wires to fall back into the wall. c. As each wire is disconnected, record wire color and terminal marking. d. Discard or recycle old thermostat. 6 CAUTION! ENVIRONMENTAL HAZARD Failure to follow this caution may result in environmental damage. Mercury is a hazardous waste. Federal regulations require that Mercury be disposed of properly. 3. Open thermostat (mounting base) to expose mounting holes. The base can be removed to simplify mounting. Press the thumb release at the top of the thermostat and snap apart carefully to separate mounting base from remainder of thermostat. 4. Route thermostat wires through large hole in mounting base.
