BALANCE POINT SET-UP Balance points limit heat pump operation when the outdoor
temperature is too high or too low. It requires an optional support module with an
outdoor temperature sensor. Consult a qualified service technician before changing
any of the values in this Sub-Menu (Sub-Menu not shown).
DISPLAY SET-UP Here the temperature scale can be changed to °C or °F, and the
temperature settings can be setup to always display or only when being changed
(see Figure 10 ). The message display, when not being used for Thermostat Set-Up
will, by default, scroll through three messages showing the status of the mode, fan, and
equipment output, a fourth date and time
can be added to this list. The date and time
must be sent daily to the thermostat from
the automation system to maintain the
accurate time. If this programming cannot
be done, it is best to not have the time
and date displayed.
