About Advanced Features & Operation

SOFT START - This feature is utilized in multiple thermostat
installations controlled by the Dry Contact terminals.
Assigning a unique Soft Start number to each thermostat
will stagger the turn on times, even though the Dry
Contact closes, for all the thermostats connected, at the
same time. Each Soft Start number represents a multiple
of 30 seconds from the Dry Contact closure.
For example, #1 = turn on 30 seconds after Dry Contact
closure, #2 = turn on 60 seconds after closure, #3 = turn
on 90 seconds after closure, and so on. See
page 14,
step 11,
to configure the thermostat for Soft Start.
DUAL SETPOINT BEHAVIOR - The adjustable setpoint range
is: 35 - 99 degrees in Fahrenheit and 7 - 35 degrees in
Centigrade. When in the modes Heat or Cool, this
adjustable range is unhampered.
When adjusting any Auto mode, including programming
Occupied and Unoccupied periods, the thermostat will not
allow the Heat setpoint to get closer to the Cool setpoint
than the value programmed as the minimum difference in
step 7, page 13.
When entering the Auto mode from Cool, the Heat and
Cool setpoints will remain spread apart by the amount
that they were adjusted, prior to entering Auto.
For example: If the Cool setpoint was set to 80 while
in the Cool mode and the Heat setpoint was adjusted to
70 while in the Heat mode, upon entering the Auto mode
the Heat and Cool setpoints would be 80 and 70.
Both
setpoints would then move up and down together, (in this
example spread by 10 degrees), by pressing the up or
down buttons.
To move the Heat and Cool setpoints closer together,
enter the Cool or Heat mode by pressing the Mode button,
then adjust the setpoint(s) closer together. Heat is limited
to how close it can come to Cool by
step 7, page 13
