B) BALANCE POINTS (Cont.)
1.
LOW BALANCE POINT
– the outdoor temperature below which compressor terminals
will not be energized.
2.
HIGH BALANCE POINT
– the outdoor temperature above which the auxiliary heat terminal
will not be energized in the HEAT mode (does not effect Emergency Heat operation).
C) DISPLAY OPTIONS
1.
TEMPERATURE SCALE
– all temperatures displayed including room temperatures and
set points can be °F or °C.
2.
SHOW TEMPERATURE SET POINTS ALWAYS
– keeps the temperature settings visible on
the display at all times.
3.
SHOW TEMPERATURE SET POINTS ONLY IF CHANGED
– displays the temperature
settings (heat and/or cool) only when the user changes them. The first press of either
the up or down adjust buttons will display the settings.
4.
SHOW DATE AND TIME
– the message display will, by default, scroll three messages
showing the status of the mode, fan and equipment outputs. A fourth date and time can be
added to this list. However, the automation system must transmit the time and date to
the thermostat at least once a day. If the automation system is not capable of doing
this, the date and time can be configured not to show.
11. TO ACCESS THESE HVAC SET-UP FEATURES
When first powered up, the message display will scroll through the current mode status,
fan status, and heating/cooling output status. This is referred to as Passive Display because
you do not interact with it. To get into the Set-Up Menu, press the Enter button
and Mode button at the same time. This is referred to as User Interactive Display, as the user
navigates through various menu and sub-menu selections to change variables.
