Remote Thermostat
To control the unit with a wall-mounted thermostat:
1) Pull the disconnect switch.
2) Unscrew and remove the control box panel.
3) After selecting which side you want to run your thermostat
wire through, run the wires through the side hole in the box
to reach the connection terminal for the wiring.
4) Make the wire connections, appropriately matching the
wires as shown in the wiring diagram.
5) Once each wire is matched and connected, the unit is now
controlled by the thermostat.
6) Reattach the control box cover.
RT5 (Two speed fan) RT4 (One speed fan)
Cool Off Heat
Auto On
All Friedrich Vert-I-Pak units are factory configured to be
controlled by using a 24V single stage remote wall mounted
thermostat. The thermostat may be auto or manual changeover
as long as the control configuration matches that of the
Vert-I-Pak unit.
NOTE: An improperly operating, or poorly located room
thermostat can be the source of perceived equipment
problems. A careful check of the thermostat and wiring
must be made then to insure that it is not the source of
problems.
Manual Changeover Thermostat
For Heat Pump equipped units: a single stage, heat/cool
thermostat with a terminal for a reversing valve operation is
required. Terminal “B” should be continuously energized in the
heat mode and terminal “G” should be energized whenever
there is a call for heating or cooling. (Typically, a single stage,
heat/cool thermostat designed for use with electric heat
systems will meet the above requirements).
Location
The thermostat should not be mounted where it may be
affected by drafts, discharge air from registers (hot or cold),
or heat radiated from the sun or appliances.
The thermostat should be located about 5 Ft. above the
fl oor in an area of average temperature, with good air
circulation. Close proximity to the return air grille is the
best choice.
Mercury bulb type thermostats MUST be level to control
temperature accurately to the desired set-point. Electronic
digital type thermostats SHOULD be level for aesthetics.

Desk Control Terminals
The Friedrich VERT-I-PAK 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 9).
Whenever the switch closes, the unit operation will stop.

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 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 field supplied.
Note: The desk
control system and
switches must be
field supplied.

NOTE: It is the installer’s responsibility to ensure that all
control wiring connections are made in accordance with
the Freidrich installation instructions. Improper connec-
tion of the thermostat control wiring and/or tampering with
the unit’s internal wiring can void the equipment warranty.
Questions concerning proper connections to the unit
should be directed to the factory: 210-357-4400.

The new Friedrich Vert-I-Pak has state of the art features to improve guest comfort and conserve energy. Through
the use of specically designed control software, Friedrich has accomplished what other Manufacturer’s have only
attempted – a quiet, dependable, affordable and easy to use Vert-I-Pak.
Below is a list of standard features on every Friedrich VPAK and their benet to the owner.
Quiet Start/Stop
Fan Delay
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 ve seconds prior to en-
ergizing 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.
Remote Thermostat
Operation
VPAK units are thermostat controlled.
Internal Diagnostic
Program
The new Friedrich digital VPAK features a self diagnostic program that can alert maintenance to compo-
nent failures or operating problems. The internal diagnostic program saves properties valuable time when
diagnosing running problems.
Service Error Code
Storage
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.
Room Freeze
Protection
When the VPAK 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 xtures.
Random
Compressor Restart
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.
Digital Defrost
Thermostat
The new Friedrich VPAK uses a digital thermostat to accurately monitor the outdoor coil conditions to allow
the heat pump to run whenever conditions are correct. Running the VPAK in heat pump mode save energy
and reduces operating costs. The digital thermostat allows maximization of heat pump run time.
Instant Heat
Heat Pump Mode
Heat pump models will automatically run the electric heater during compressor lock-out to quickly provide
heat when initially energized, then return to heat pump mode. This ensures that the room is heated quickly
without the usual delay associated with heat pump units.
Emergency Heat
Override
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.
Desk Control Ready
All electronic VPAK units 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 VPAK.
Indoor Coil Frost
Sensor
The frost sensor protects the compressor from damage in the event that air 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
The VPAK series units feature a indoor fan system design that reduces sound levels without
lowering airow and preventing proper air circulation.
High Efciency
The VPAK benets quality components and extensive development to ensure a quiet, efcient and
dependable unit.
Rotary Compressor
High efciency rotary compressors are used on all Friedrich VPAKs to maximize durability and efciency.
Auxiliary Fan Ready
The VPAK 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.

The Friedrich Smart Center continuously monitors the VPAK unit operation and will store service codes if
certain conditions are witnessed. In some cases the unit may take action and shut the unit off until conditions are
corrected. To access the error code menu press the ‘Heat’ and ‘High Fan’ buttons simultaneously for three sec-
onds. If error codes are present they will be displayed. If multiple codes exist you can toggle between messages
using the temp up button. To clear all codes press the temp down button for three seconds while in the error code
mode. To exit without changing codes press the ‘Low Fan’ button.

For service and diagnostic use only, the built-in timers and delays on the VPAK may be bypassed by pressing the ‘Cool’ and
‘Low Fan’ buttons simultaneously for three seconds while in any mode to enter the test mode. CE will be displayed when en-
tering test mode, and oE will be displayed when exiting. The test mode will automatically be exited 30 minutes after entering it
or by pressing the ‘Cool’ and ‘Low Fan’ buttons simultaneously for three seconds.
Note: To access the Test Mode while under remote wall thermostat operation, remove thermostat’s wires at the
terminal block on the electronic control board then connect a jumper wire between GL and GH.

Wall Thermostat Connections:
• The control is compatible with a st
andard single stage heat and cool Wall
Thermostat.
• It is compatible with Friedrich RT4 and RT5 Wall thermostats.
• Terminals are:
C – Common ground terminal.
W – call for heating.
Y – call for cooling,
R – 24V power from Electronic control to Wall Thermostat.
GL - call for low Fan.
GH- call for high fan
B – call for heat pump reversing valve.
The outputs of a single stage Heat and Cool Wall thermostat:
• When a call for cool from Wall thermostat the signals will go to
terminal Y, GL or GH.
• When a call for heat from Wall thermostat the signals will go to
terminal W, B, GL or GH.
• When a call for Fan Only from Wall thermostat the signals will go
to terminal GL or GH.
Remote T-stat Operation Features:
All buttons on the electronic control board will be disabled except “Heat”
When power is applied to L1 and L2, the Power LED will be lit on the
electronic control.
and “High Fan” buttons during Error code mode operation.
COMMON CONTROL FEATURES FOR COOL WITH ELECTRIC HEAT
AND HEAT PUMP WITH ELECTRIC HEAT UNITS:
Power On and Off Features on the Electronic Control:
Temperature set:
This feature will depend on Wall Thermostat.
˚F/˚C set:
This feature will depend on Wall Thermostat.
Fan speed, fan cycle on/off or continuous operation
This feature will depend on Wall Thermostat. For single speed Wall
Thermostat, user needs to choose between GH terminal (High Fan) or
GL terminal (Low Fan). For a two speed fan Wall Thermostat, connect
both GL and GH. If the PCB receives signals for both GL and GH at the
same time, only High Fan turns on.

Reversing valve:
Always de-energized when “Cool” switch is selected on thermostat.
Compressor operation:
If ambient indoor temperature is above set point temperature depending on t-stat differential and
the compressor is not time delayed, turn on compressor. If ambient indoor temperature is
below set point depending on t-stat differential, turn off the compressor.
Compressor time delay:
The time delay feature is de-energized for a period of time that varies randomly from 180 to
240 seconds. Compressor time delay is initiated every time the compressor is “off” due to:
(1) Satisfying the temperature set point,
(2) Changing mode to fan only
(3 )Turning the unit off.
(4) Control is rst energized or when power is restored after failure
Note: Time delay is disabled during Test Mode.
Indoor coil frost protection (Error Code 07):
While in cool mode: If the indoor coil frost protection sensor reads 30°F for 2 minutes continu-
ously, turn off the compressor, but continue fan operation. While the compressor is out and the
fan is running: when the indoor coil frost protection sensor reaches 45°F, turn on the compres-
sor. However, the compressor must still wait a standard time of 180 to 240 seconds. While 07
ash, heat operation is disabled.
Fan delay:
This is only for fan ‘cycle’ mode and not for fan ‘continuous’ mode. When unit cycles cool-
ing ON – start the fan 5 seconds EARLY. When unit cycles cooling OFF – DELAY the fan off
for 30 seconds. Note: the fan delay is disabled during Test Mode.
Reversing valve: Always de-energized when “Heat” button is pushed.
Compressor operation: Compressor does not operate in this mode.
Electric heat operation: If temp is below set point, depending on t-stat differential, turn on
electric heat. If Ambient is above set point depending on t-stat differential, turn off the electric
heat.
Fan delay: This is only for fan ‘cycle’ mode and not for fan ‘continuous’ mode. When unit
cycles heating ON – start the fan 5 seconds EARLY. When unit cycles heating OFF – DELAY
the fan off for 15 seconds. Note: the fan delay is disabled during Test Mode.

Reversing valve:
Always energized when “Heat” is selected on thermostat.
Compressor operation depends on t-stat settings:
If ambient indoor temperature is below the set point temperature depending on t-stat differential
and the compressor is not time delayed, turn on compressor. If ambient indoor temperature is
below set point depending on t-stat differential, turn off the compressor.
Compressor Time Delay:
The time delay feature is de-energized for a period of time that varies randomly from 180 to 240
seconds. Compressor time delay is initiated every time the compressor is “off” due to:
(1) Satisfying the temperature set point,
(2) Changing mode to fan only
(3 )Turning the unit off.
(4) When control is rst energized or when power is restored after failure
Note: Time delay is disabled during Test Mode.
Heat:
When there is a call for heat from the Wall thermostat the PCB will receive signals on terminal
W, B, GL or GH. During compressor time delay, electric heat will turn on rst. When com-
pressor time delay is UP, the compressor will turn on.
Condition:
If outdoor coil temperature sensor drops to 30°F for less than 2 consecutive minutes, then unit
will switch to electric heat. Thereafter, unit will switch back to Heat Pump heat if outdoor coil
temperature sensor rises to 45°F or greater.
Fan delay:
This is only for fan ‘cycle’ mode and not for fan ‘continuous’ mode. When unit cycles cool-
ing ON – start the fan 5 seconds EARLY. When unit cycles cooling OFF – DELAY the fan off
for 30 seconds. Note: the fan delay is disabled during Test Mode.
Emergency Heat:
When compressor fails in heating season, allows user to disable Heat Pump. Heating with elec-
tric heat only (See DIP switch position 7).
