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.

Electronic Control Error Code Diagnostics and Test Mode

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.
