Thermostat Setpoints Programming
The thermostat registers (TOS and THYST ) can be programmed or read via the 2–wire interface. TOS is
accessed by setting the DS75 data pointer to the 03h location, and that for the THYST setting is 02h.
The format of the TOS and THYST registers is identical to that of the Thermometer register; that is, 12–bit
2’s complement representation of the temperature in
°C. The user can program the number of bits (9, 10,
11, or 12) for each TOS and THYST that correspond to the thermometer resolution mode chosen. If the 9–bit
mode is chosen, for example, the 3 least significant bits of TOS and THYST will be ignored by the
thermostat comparator. The format for both TOS and THYST is shown below in Table 6. The power–up
default of TOS is 80
°C and that for T
HYST is 75
°C.

If the user does not wish to take advantage of the thermostat capabilities of the DS75, the 24 bits can be
used for general storage of system data that need not be maintained following a power loss. The O.S.
output should be left floating if this is done.
