Setting the DIP Switch
Set the DIP switch located on the thermostat circuit board (FIG. 4) according to the ap plication needs (see the
DIP Switch Settings table below for details).
The following table shows what each switch corresponds to depending on position. Switch one should be set in
the “OFF Servant” position unless you plan to broadcast readings from remote temperature sensors to other
thermostats in the system when there is no control system in place.

Reassembly

No tools required – line up pins on circuit board with the corresponding ter minal blocks. Use your hands to
push the front panel securely to the mounted base.
