Friedrich PTAC Digital Control and Unit Features The new Friedrich digital PTAC has state of the art features to improve guest comfort, indoor air quality and conserve energy. Through the use of specifically designed control software for the PTAC industry Friedrich has accomplished what other Manufacturer’s have only attempted – a quiet, dependable, affordable and easy to use PTAC. Below is a list of standard features on every Friedrich PTAC and their benefit to the owner.
Instant Heat Heat Pump Mode Heat pump models will automatically run the electric heater to quickly bring the room up to temperature when initially energized, then return to heat pump mode. This ensures that the room is brought up to temperature quickly without the usual delay associated with heat pump units. Even Heat Monitoring The digital control monitors indoor conditions to ensure that the room temperature is within five degrees of the setpoint.
System Configuration Fresh Air Vent Control The vent control lever is located on the left side of the unit, behind the front panel. NOTE: Figure 28 Air Vent Control Location VENT CONTROL (Pull lever through label to operate) The vent door shipping hardware must be removed before using the vent control lever. See page 17, Figure 21, (Remove Shipping Screw from Vent Door if present). When vent door is set to CLOSE, only the air inside the room is circulated and filtered, See Figure 28.
Digital Control User Input Configuration The adjustable control dip switches are located at the lower left hand portion of the digital Smart Center. The inputs are only visible and accessible with the front cover removed from the PTAC. Dip Switch Setting 1. Emergency Heat Override – Switch 1 In the unlikely event of a compressor failure a heat pump unit may be switched to operate in only the electric heat mode until repairs can be made. Moving Dip Switch 1 to ‘ON’. 2.
Digital Control Operation Figure 32 Digital Control Panel High Heat Med Cool Low Fan Fan Speed Mode Power Temperature FRP030 °F vs. °C Display Heat/Cool Models (PDE) The unit is factory configured to display all temperatures in degrees Fahrenheit (° F). To switch to degrees Celsius press the ‘Fan Only’ and ‘Low Fan’ buttons simultaneously for three seconds. The display will show a ‘C’ as acknowledgement of the change.
Remote Control Thermostat Installation Install Thermostat 1. Approximately 5 ft. from the floor. 2. Close to or in a frequently used room, preferably on an inside wall. 3. On a section of wall without pipes or ductwork. The Thermostat should NOT be mounted: 1. Close to a window, on an outside wall, or next to a door leading outside. 2. Where it can be exposed to direct sunlight or heat, such as the sun, a lamp, fireplace, or any ther temperatureradiating object which may cause a false reading. 3.
Desk Control Terminals The Friedrich PD model PTAC has built-in provisions for connection to an external switch to control power to the unit. The switch can be a central desk control system or even a normally open door switch. For desk control operation connect one side of the switch to the D1 terminal and the other to the D2 terminal (See Figure 31, Page 23). Whenever the switch closes the unit operation will stop. NOTE: The desk control system and switches must be field supplied.
Final Inspection & Start-up Checklist q Inspect and ensure that all components and accessories have been installed properly and that they have not been damaged during the installation process. q Check the condensate water drain(s) to ensure they are adequate for the removal of condensate water, and that they meet the approval of the end user. q Ensure that all installations concerning clearances around the unit have been adhered to.
Basic Troubleshooting COMPLAINT Unit does not operate. Unit trips circuit breaker or blows fuses. LCDI Power Cord Trips (Reset Button Pops Out) NOTE: A damaged power supply cord must be replaced with a new power supply cord obtained from the product manufacturer and must not be repaired. Unit does not cool/heat room sufficiently, or cycles on and off too frequently 28 CAUSE SOLUTION ●● Unit turned off. ●● Turn unit on ●● Thermostat is satisfied. ●● Raise/Lower temperature setting.
COMPLAINT Unit does not cool/heat room sufficiently, or cycles on and off too frequently CAUSE ●● The air conditioner has insufficient heating capacity to match the heat loss of the room. ●● Check the heating capacity of your unit. Air conditioners are sized to meet the cooling load and heater size is then selected to meet the heating load. In extreme, northern climates, room air conditioners may not be able to be used as a primary source of heat.
