only visible and accessible with the front cover removed from

Room Freeze Protection – Switch 6
Units are shipped from the factory with the room freeze protec-
tion 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.
Emergency Heat Override – Switch 7
Units are shipped from the factory with the room emergency
heat override disabled. 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, by moving Dip
Switch 7 to ‘ON’.
Discharge Air Sensor Override – Switch 8
This switch MUST remain in the “ON” position for Vert-I-Pak
models, since they do not use a discharge air sensor. If the
switch is positioned in the “OFF” position on these models it
will result in the erroneous display Error Code 14 indicating that
the Discharge air temperature sensor is open or shorted.
Note: In order for the control to recognize “Dip” switch
setting changes, the unit must be disconnected
from power supply when making any configuration
changes.
Error Code Diagnostics
The VPAK electronic control continuously monitors the Vert-I-Pak
unit operation and will store error 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 seconds. If error codes
are present they will be displayed. If multiple codes exist you
can toggle between error codes 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 losing codes
press the ‘Low Fan’ button.
Button Location for Vert-I-Pak Models
