4.3.7 FUTURE OUTDOOR SENSOR
An optional outdoor sensor may be installed to enable
the thermostat to display the temperature outside your
home. This sensor may also be used to instruct the unit
to switch from a heat pump to another source of heat.
Once installed the outdoor temperature will alternate with
the time in the display. To install an outdoor sensor refer
to the Installation Section of this manual. To enable an
outdoor sensor or change heat pump settings refer to the
Installers Setup Section of this manual.
4.3.8 FUTURE REMOTE INDOOR SENSORS
Up to three optional indoor sensors may be installed. The
temperature measurements of all active indoor sensors
will be averaged and used in temperature control. With
remote indoor sensors functioning, the units' internal
temperature sensor may be enabled or disabled to allow
the thermostat to be mounted in locations that would
otherwise be non-ideal.
To install indoor temperature sensors refer to the
Installation Section of this manual. To enable or disable
the units internal sensor or other remote indoor tempera-
ture sensors refer to the Installers Setup Section of this
manual.
