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.
