The DIP switches can however be changed to customize the thermostat’s operation to your particular needs. This should only be done after consulting with your contractor.

The Model 8554 DIP switches control the following functions:

No. 1 – 4 min. / 2 min. Minimum Equipment On/Off Times. This switch is factory preset at 2 minutes. This switch provides short cycle protection for the heat pump. If you feel that the heat pump turns on and off too many times per hour, ask your contractor about changing the switch to a 4 minute minimum on time. Keep in mind, however, that this may increase the overall temperature variation in the house due to longer run and off times. DO NOT change the position of this switch without first consulting with your contractor.

No. 2 – Keypad Lock. If tampering with the thermostat is expected and unwanted, the keypad can be locked by moving this switch from the factory set OFF position to the ON position. This should not be done until all programming is finalized. In the locked position only the following functions can be done:

•The outdoor temperature button will display the outdoor temperature.

•The DECREASE button or INCREASE button will temporarily change the set point a maximum of ±6°F (±3°C) for a period of 3 hours, before the thermostat

automatically returns to the original program.
