RAMPING
This function is used to activate or deactivate the
ramping function and set its value. The ramping
function automatically reduces the main set point
by the set value every 24 hours.
The ramping setting is adjusted in 0.01 degree
decrements from a minimum setting of OFF,
-0.01°F (-0.01°C) to a maximum setting of
-0.99°F (-0.50°C).
The main set point must be greater than the
limit
.
Adjusting ramping:
•
rotate the selector dial to position (9),
•
rotate the adjuster dial counter clockwise to
increase the ramping rate, and clockwise to
decrease it.
The ramping setting is displayed on the MST-2B.
NOTE: When ramping is activated, the main
set point temperature cannot be manually
adjusted.
Ramping automatically shuts OFF when the
minimum temperature limit is reached!
Example: The main set point temperature is set
to 70°F and ramping is adjusted to -0.05°F. The
following day the main set point temperature
drops to 69.95°F followed by 69.90°F on the
next day. Although the main set point real
value decreases, the display will be changed
after 10 days. The main set point will then be
69.5°F.
