Step 4 — Space Temperature Averaging —
Ap-
plications that require averaging using multiple remote space
temperature sensors can be satisfied using either 4 or 9 sensors
as shown in Fig. 25. For single space temperature sensor wir-
ing, refer to the base unit installation instructions. Temperature
sensor calibration can be checked by measuring actual resis-
tance at a temperature with an ohmmeter and comparing to the
values listed in Table 2.
NOTE: Only Totaline® sensors (P/N P274-0401) may be
used for standard space temperature sensor averaging. Sen-
sors must be used singly or in multiples of 4 and 9, with
total sensor wiring not to exceed 1000 feet.
Step 5 — Set Thermostat Configuration —
Configuration options, like DIP switch settings, are intended to
be selected at installation and are not normally modified by the
homeowner. These options are not discussed in the corre-
sponding owner’s manual and must be done as part of the
installation. A special procedure for the thermostat allows
entry into the Configuration mode. To enter Configuration
mode, press and hold the Fan button for approximately 10 sec-
onds. The room temperature display will disappear and the
option number (smaller) will be displayed in the upper right
corner on the thermostat display. The option number will be
flashing and can be changed with the Up and Down Arrow
buttons. Once the desired configuration option is displayed,
press the Set Time/Temp button to configure the option. See
Table 3. The option number will stop flashing and the configu-
ration value (larger) on the left of the thermostat display will
flash. Change the configuration value with the Up and Down
Arrow buttons. Press the Set Time/Temp button again to save
the configuration and change a different configuration. Record
all chosen configuration options on page 16. Press the End but-
ton to exit Configuration mode. The thermostat will automati-
cally exit Configuration mode if no button is pressed for 3
minutes.
NOTE: When setting the configuration on the thermostat,
the configuration “on” is displayed as On, and the configu-
ration “off” is displayed as OF.
