PACKAGED TERMINAL A/C Service Manual Heat Controller Controller Functions and Operating Methods The relationship between Centigrade and Fahrenheit is: Tcentigrade=Tfahrenheit*1.8+3.2 A. Temperature Parameter n Indoor setting temperature (Tpeset) n Indoor ambient temperature (Tamb) B. System Basic Function The compressor has a 3 minute time delay before it will start as a protective feature. Once the compressor begins to run, the compressor cannot be stopped by changing the set temperature.
Heat Controller Service Manual Packaged Terminal A/C Controller Function and Operating Method continued 7. Open circuit and short circuit of temperature sensor If the temperature sensor has an open circuit, it will send an error signal. The error signal is displayed (see table below).
PACKAGED TERMINAL A/C Service Manual Heat Controller D. Special Functions and Features The PTAC unit is designed to be operated by the unit’s main control panel, however, factory installed connections are included to allow the PTAC to operate via remote thermostat or energy management input (front desk control).
Heat Controller Service Manual SUGGESTIONS: 1. To size transformer, use the following equation: Quantity of PTAC units x 12 va=Transformer Size (va) Example: 110 PTAC units x 12 va = 1320 vaTransformer 2. Following are American Wire Gauge recommended sizes: AWG WIRE SIZE NO.
PACKAGED TERMINAL A/C Service Manual Heat Controller Wall Thermostat Connections A standard low voltage wall thermostat can be wed with the PTAC unit’s factory installed terminal. Multiple PTACs can even be connected together on a single wall thermostat.

PACKAGED TERMINAL A/C Service Manual Heat Controller E. Unit controls The PTAC can be configured by the display and a set of dip switches. 1. TEMP CONTROL Temp Control is used to maintain room temperature. Compressor will cycle on and off to keep room at the requested level of comfort. COOLER—Lowers temperature. (Minimum temperature setting is 61°F/16°C) WARMER—Raises temperature. (Maximum temperature setting is 86°F/30°C) 2. FAN SPEED, MODE & ON/OFF FAN SPEED—Set fan operation for HI, MED, or LO speed.
Heat Controller Service Manual Packaged Terminal A/C KEYPAD CONFIGURATION Allows further configuration of system to desired application such as whether th unit displays in °F or °C, whether the display shows the set point or room air temperature, and to set controls for sensor biasing. Changes do not take affect until power is cycled on the unit. To enter Keypad configuration Cycle power to unit.
PACKAGED TERMINAL A/C Heat Controller Service Manual DIP SWITCHES Auxiliary dip switch controls are located behind front panel, through an opening below the control panel. Dip switches are accessible without opening the control box. Unit must be powered OFF to effectively change their status. Factory settings for dip switches will be in the DOWN position. See Table—Dip Switch Functions for functions of each dip switch position.
Heat Controller Service Manual Packaged Terminal A/C F. Protective Features 1. Frost Protection Mode (heat pump): When the compressor is running under wired controller’s heating signal. If T outer tube ≤ 28°F (-2°C) is detected for 1 minute successively, the compressor and outdoor fan will stop running. Then indoor fan will run normally according to the wired controller’s signal. If the heating is required then the heat pump operation will stop the compressor and run the electric heater solely.

Heat Controller Service Manual Packaged Terminal A/C POWER CONNECTION OPTIONS Appropriate power cord accessory kit is determined by the voltage, and amperage of the branch circuit. The unit does not come with a power cord (or hard wire kit). An accessory power cord kit must be ordered to connect the unit to the outlet. If the unit is to be hard wired, an accessory hard wire kit must be ordered. IMPORTANT: For 265V units, if a power cord is selected, it must plug into the 265V subbase accessory.
PACKAGED TERMINAL A/C Service Manual Heat Controller PREVENTATIVE MAINTENANCE Preventative maintenance is essential to proper unit operation, efficiency and longevity. To ensure equipment operates properly, it must be properlymaintained. Equipment operation should be checked and verified several times during each year. During regular unit inspection and maintenance, follow the guidelines below: • Clean both sides of outdoor coil. (Never use high pressure spray on coils.
