Friedrich Digital Control 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 speciﬁ cally 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 beneﬁ t to the owner.

Digital Temperature Readout

One-Touch Operation

Individual Mode and Fan Control Buttons

Quiet Start/Stop Fan Delay

Remote Thermostat Operation

Wireless Remote Control Ready

Internal Diagnostic Program

Service Error Code Storage

By digitally monitoring desired room temperature the room is controlled more precisely than conventional systems. The large, easy to read LED display can show either set-point or actual room temperature as selected by owner.

When the unit is powered off the unit can be returned directly to heating or cooling mode by pressing the ‘Heat’ or ‘Cool’ buttons without the confusing power up sequence of some controls. One-touch control takes guesswork out of unit control delivering a more enjoyable experience and eliminating front-desk calls.

By having separate control buttons and indicators for both fan and mode settings the Friedrich digital control eliminates the confusion of previous digital PTACs. The accurate temperature setting provides greater guest comfort than other systems.

The fan start and stop delays prevent abrupt changes in room acoustics due to the compressor energizing or stopping immediately. Upon call for cooling or heating the unit fan will run for ﬁ ve seconds prior to energizing the compressor. Also, the fan off delay allows for “free cooling” by utilizing the already cool indoor coil to its maximum capacity by running for 30 seconds after the compressor.

Some applications require the use of a wall mounted thermostat. All new Friedrich PTACs may be switched from unit control to remote thermostat control easily without the need to order a special model or accessory kit.

Guests can adjust the temperature and mode of the unit through the use of an optional hand held wireless remote, improving guest comfort and relaxation.

The new Friedrich digital PTAC features a self diagnostic program that can alert maintenance to component failures or operating problems. The internal diagnostic program saves properties valuable time when diagnosing running problems.

The self diagnosis program will also store error codes in memory if certain conditions occur and correct themselves such as extreme high or low operating conditions or activation of the room freeze protection feature. Storing error codes can help properties determine if the unit faced obscure conditions or if an error occurred and corrected itself.

Constant Comfort Room Monitoring

Electronic Temperature Limiting

Room Freeze Protection

Random Compressor Restart

Digital Defrost Thermostat

The on-board processor monitors time between demand cycles (heat or cool) and will cycle the fan every 9 minutes to sample the room condition and determine if the desired conditions are met. This allows the room to have similar beneﬁ ts to a remote mounted stat without the complication or cost of a wall mounted thermostat.

By limiting the operating range the property can save energy by eliminating “max cool” or “max heat” situations common with older uncontrolled systems. The new electronic control allows owners to set operating ranges for both heating and cooling independently of one another.

When the PTAC senses that the indoor room temperature has fallen to 40°F the unit will cycle on high fan and the electric strip heat to raise the room temperature to 46°F then cycle off again. This feature works regardless of the mode selected and can be turned off. The control will also store the Room Freeze cycle in the service code memory for retrieval at a later date. This feature ensures that unoccupied rooms do not reach freezing levels where damage can occur to plumbing and ﬁ xtures.

Multiple compressors starting at once can often cause electrical overloads and premature unit failure. The random restart delay eliminates multiple units from starting at once following a power outage or initial power up. The compressor delay will range from 180 to 240 seconds.

The new Friedrich PTAC uses a digital thermostat to accurately monitor the outdoor coil conditions to allow the heat pump to run whenever conditions are correct. Running the PTAC in heat pump mode save energy and reduces operating costs. The digital thermostat allows maximization of heat pump run time.

920-087-04 (3-05)

Friedrich Digital Control Features Continued

Instant Heat Heat Pump Mode

Even Heat Monitoring

Fan Cycle Control

Emergency Heat Override

Desk Control Ready

Indoor Coil Frost Sensor

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.

The digital control monitors indoor conditions to ensure that the room temperature is within ﬁ ve degrees of the setpoint. If necessary the unit will cycle the electric heat to maintain the temperature. This feature ensures guest comfort by delivering the heating beneﬁ ts of an electric heater while maintaining the efﬁ ciency beneﬁ ts of a heat pump.

The owner may choose between fan cycling or fan continuous mode based on property preference. (Note: Even heat monitoring and quiet start/stop fan delay only operate in fan cycle mode) Fan continuous mode is used to keep constant airﬂ ow circulation in the room during all times the unit is ‘ON’. Fan cycle will conserve energy by only operating the fan while the compressor or electric heater is operating.

In the event of a compressor failure in heat pump mode the compressor may be locked out to provide heat through the resistance heater. This feature ensures that even in the unlikely event of a compressor failure the room temperature can be maintained until the compressor can be serviced.

All Friedrich digital PTACs have low voltage terminals ready to connect a desk control energy management system. Controlling the unit from a remote location like the front desk can reduce energy usage and requires no additional accessories at the PTAC.

The frost sensor protects the compressor from damage in the event that airﬂ ow is reduced or low outdoor temperatures cause the indoor coil to freeze. When the indoor coil reaches 30°F the compressor is diabled and the fan continues to operate based on demand. Once the coil temperature returns to 45°F the compressor returns to operation.

Ultra-Quiet Air System

High Efﬁ ciency

Single Motor

Rotary Compressor

Auxiliary Fan Ready

Aluminum Endplates

Seacoast Protection

Top Mounted Antimicrobial Air Filters

The new Friedrich PD series units feature a indoor fan system design that reduces sound levels without lowering airﬂ ow and preventing proper air circulation.

The Friedrich PTAC beneﬁ ts quality components and extensive development to ensure a quiet, efﬁ cient and dependable unit.

Friedrich’s single-motor design allows for enhanced outdoor airﬂ ow and simpliﬁ es the unit design without the need for redundant components.

High efﬁ ciency rotary compressors are used on all Friedrich PTACs to maximize durability and efﬁ ciency.

The Friedrich PTAC features a 24V AC terminal for connection to an auxiliary fan that may be used to transfer air to adjoining rooms. Auxiliary fans can provide conditioning to multiple rooms without the requirement of multiple PTAC units.

All Friedrich PTACs are built with .04" endplates made from aluminum as opposed to steel. The endplates are typically the most susceptible area for corrosion and aluminum is far more resistant to corrosion than even coated steel.

Optional Seacoast protection is available to protect the outdoor coil from harsh environments. The Friedrich Seacoast process includes dipping the entire outdoor coil in a 7-step coating process that provides superior protection to only coating the ﬁ ns of the coil.

All Friedrich PTAC return air ﬁ lters feature an anti-microbial element that has proven to prevent mold and bacterial growth in laboratory testing. PDXFT replacement ﬁ lter kits feature the same anti-microbial agent. All ﬁ lters are washable and reusable and are easily accessed from the top of the unit without the removal of the front cover.

Filtered Fresh Air Intake

Friedrich PTAC units are capable of introducing up to 70 CFM of outside air into the conditioned space. The outdoor air passes through a washable mesh ﬁ lter to prevent debris from entering the airstream.

Section II — Deep Wall Installation (PXWE)

If the wall is thicker than allowed in the notes in Figure 6, a sheet met al wall sleeve ex ten sion and ﬂ ashing MUST be used.

Installation Instructions for the PXWE – 4" Wall Sleeve Extension

The following points MUST be considered when installing a wall sleeve extension:

1 Provision must be made to direct excess condensate from

the back of the wall sleeve into the extension then outside the building or to a drainage system.

2. Air bafﬂ es must be mounted to properly direct air ﬂ ow to and from the condenser.

3. The wall sleeve extension design must allow for the prop er mount ing of the grille.

4. Caulking is required at all sites where condensate or ex ter nal water could potentially inﬁ ltrate into the building.

5. Fabricate and install metal ﬂ ashing in wall to ser ve as a dr ip panel. Refer to drawing for more information.

6. Condensate notches and overﬂ ow slots must be kept clear of sealant and gaskets so con den sate can ﬂ ow freely into the wall sleeve extension.

NOTE: Improper fabrication or installation of a wall sleeve extension will impair PTAC performance.

Extension Installation

Secure the wall sleeve extension to the wall sleeve before installing it in the wall. Refer to Figure 8 for a guide for fabrication of a condensate drip panel. The panel MUST extend the full depth of the wall sleeve and the wall sleeve extension.

Pay particular care in seal ing and caulking the panel where it makes contact with the wall sleeve (see Figure 8). After installation in the wall, secure with fasteners through the sides. Use a good grade of silicone sealant around the sleeve extension. Seal all exposed screw heads. When the installation is complete, the outside grille should be attached to the wall sleeve extension.

Digital Control User Input Conﬁ guration

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) Electronic Temperature Limiting – Switches 1-4

The digital control is set from the factory to allow a temperature range between 60°F and 90°F in both heating and cooling mode. Dip Switches 1-4 can be used to set high and low limits for either heating or cooling or both.

From the factory all four switches are in the up ‘ON’ position. The charts to the right show the available electronic limiting ranges.

2) Fan Cycle Control – Switch 5

All PTACs are shipped from the factory with Dip Switch 5 in the ‘OFF’ position to cycle the fan only when there is a demand for the compressor or heater. As an option the fan may be set to ‘continuous’ mode by switching Dip Switch 5 to ‘ON’ position to run the fan continuously while the unit is powered on. To ensure that the room temperature is maintained evenly while in fan cycle mode the Even Temp Load Anticipation feature is enabled. Quiet Fan Delay is also enabled in fan cycle mode to lessen the acoustical change between compressor start up and shut off by running the fan for 5 seconds before each demand cycle, and 30 seconds after cooling or 15 seconds after heating cycles.

3) Room Freeze Protection – Switch 6

Units are shipped from the factory with the room freeze protection disabled. Room Freeze Protection can be switched on at the owner’s preference by moving Dip Switch 6 to ‘ON’. This feature will monitor the indoor room conditions and in the event that the room falls below 40°F the unit will cycle on high fan with the electric heater. This occurs regardless of mode.

4) Emergency Heat Override – Switch 7

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 7 to ‘ON’.

Note: PTAC must be disconnected from power supply when making any conﬁ guration changes.

Remote Thermostat and Low Voltage Control Connections

Remote Thermostat

All Friedrich PD model PTAC units are factory conﬁ gured to be controlled by either the chassis mounted Smart Center or a 24V single stage remote wall mounted thermostat. The thermostat may be auto or manual changeover as long as the control conﬁ guration matches that of the PTAC unit.

To control the unit with a wall mounted thermostat follow the steps below:

1) With the front cover removed locate the low voltage terminal strip at the lower portion of the Smart Center.

2) Remove the jumper between the ‘GL’ and GH’ terminals.

3) The control is now conﬁ gured for control by a wall thermostat. The Smart Center will no longer control the unit.

4) If desired the accessory escutcheon kit (PDXRT) is to be used, install it over the existing control panel.

Note: To revert back to the Smart Center control of the unit replace the jumper wire between the ‘GL’ and ‘GH’ terminals that was removed in step 1.

G. Fresh Air Vent Con trol

The vent control lever is located behind the front cover on the left side of the unit. The unit is shipped in the closed position with a locking screw in place. The screw must be removed to operate the lever. When the lever is back, (OPEN), outside air is mixed with indoor air. When the lever is forward, (CLOSED), no out side air is admitted into the room and room air is re cy cled through the unit.

Auxiliary Fan Control

The Smart Center also has the ability to control a 24VAC relay to activate an auxiliary, or transfer, fan. The outputs are listed as F1 and F2 on the control board.

To connect the relay, simply wire one side of the relay to F1 and the other side to F2. Anytime that the PTAC fan runs the terminals will send a 24VAC signal to the relay. The relay must be 24 VAC, 50mA or less.

Note: The relay and auxiliary fans must be ﬁ eld supplied.

NOTE: It is the installer's responsibility to ensure that all control wiring connections are made in accordance with the installation instructions. Improper connection of the thermostat control wiring and/or tampering with the unit's internal wiring can void the equipment warranty and may result in property damage, personal injury or death. Other manufacturer's PTACs and even older Friedrich models may have different control wire connections. Questions concerning proper connections to the unit should be directed to the factory.

NOTE: The vent should remain closed for peak operating ef ﬁ cien cy.

H. Air Discharge Grille

J. Routine Maintenance

NOTE: Units are to be inspected and ser viced by qual i ﬁ ed service per son nel only.

1. Clean the unit air intake ﬁ lter at least every 300 to 350 hours of operation. Clean the ﬁ lters with a mild detergent in warm water and allow to dry thoroughly before reinstalling.

2. The indoor coil (evaporator coil), the outdoor coil (condenser coil) and base pan should be inspected periodically (yearly or bi-yearly) and cleaned of all debris (lint, dirt, leaves, paper, etc.). Clean the coils and base pan with a soft brush and compressed air or vacuum. If using a pressure washer, be careful not to bend the aluminium ﬁ n pack. Use a sweeping up and down motion in the direction of the vertical aluminum ﬁ n pack when pressure cleaning coils. Cover all electrical components to protect them from water or spray.

Before reinstalling the chassis in the sleeve, inspect the

indoor blower housing, blower wheel, condenser fan blade, and condenser shroud periodically (yearly or bi-yearly) and clean of all debris (lint, dirt, mold, fungus, etc.) Clean the blower housing area and blower wheel with an antibacterial / antifungal cleaner. Use a biodegradable cleaning agent and degreaser on condenser fan and condenser shroud. Use warm or cold water when rinsing these items. Allow the unit to dry thoroughly, inspect all gasket material for deterioration (replace as necessary), and then reinstall the chassis in the sleeve.

3. Periodically (at least yearly or bi-yearly): inspect all control components, both electrical and mechanical, as well as the power supply. Use proper testing instruments (voltmeter, ohmmeter, ammeter, wattmeter, etc.) to perform electrical tests. Use an air conditioning or refrigeration thermometer to check room, outdoor and coil operating temperatures. Use a sling psychrometer to measure wet bulb temperatures indoors and outdoors.

4. Inspect the surrounding area (inside and outside) to ensure that the units' clearances have not been compromised or altered.

5. Inspect the sleeve and drain system periodically (at least yearly or bi-yearly) and clean of all obstructions and debris. Clean both areas with an antibacterial and antifungal cleaner. Rinse both items thoroughly with water and ensure that the drain outlets are operating correctly. Check the sealant around the sleeve and reseal areas as needed.

6. Clean the front cover when needed. Use a mild detergent. Wash and rinse with warm water. Allow them to dry thoroughly before reinstalling them in the chassis.

NOTE: Do not use a caustic coil cleaning agent on coils or base pan. Use a biodegradable cleaning agent and degreaser.

K. Basic Troubleshooting Techniques

Being familiar with the sequence of operation on Standard Controlled Operating Units or the operation of the Remote Thermostat Controlled Units is important. The following questions and answers may help to identify performance problems.

Environmental Effects - Cooling Mode

Is unit sized to room size area and heat load demand?

The number of people in the room, number of electrical devices, solar gains, etc. are all variable items that can affect proper sizing of the unit. Friedrich recommends that you consult with an applications engineer for proper sizing.

Is the outdoor temperature 60°F or below?

The unit is designed for outdoor temperatures above 60°F.

Is the indoor temperature 80°F or above?

Ambient indoor temperatures of 80°F or above will take a longer period of run time to cool down the area. Long run times may indicate that the unit is undersized.

Is indoor humidity high?

This condition will cause the unit to operate longer to remove humidity before noticing any cooling effect.

Has the heat load been increased by additional devices such as computer equipment, or has the room area been increased where the unit is located?

If conditions have changed, the unit may not be able to cool and condition as effectively as previously planned.

Environmental Effects - Heating Mode

Is unit properly sized to room area and heat load demand?

Is the outdoor temperature 70°F or above?

The unit is designed for outdoor temperatures below 70°F. Is the indoor temperature 60°F or below? Ambient indoor temperatures of 60°F or below will take a longer period of run time to heat the area. Long run times may indicate that the unit is undersized.

Has the room area been increased where the unit is located?

If the area where the unit is located has been increased, the unit may not provide adequate heat.

Insufﬁ cient Maintenance and Inspection

Installation errors are the most common cause of poor performance. Please follow installation instructions carefully. If other problems exist, see Maintenance and Inspection Troubleshooting Guide below.

Maintenance and Inspection Troubleshooting Guide

CAUSE RESULT

System is not serviced or inspected regularly (semiannually or annually).
