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) 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’.
