SETTING CN 616 TC1 TO CONTROL 4 ZONE FURNACE.
TO RUN IN "RAMP AND SOAK1" MODE [Profile]
The difference between STANDARD MODE and RAMP AND SOAK
MODE is that in RAMP AND SOAK controller can run up to 20 control
segments for each zone. The first segment, for each zone, is made up of
target temperature and rate of change (ramp). Subsequent segments are
made up of setpoint, slope and time. Only one parameter (slope or time)
need to be set. If time is set when new setpoint is different from the
previous one, time will be converted to slope. The other parameter should
be set at 0. If slope is set for the segment with no change in setpoint, the
segment will be ignored and control will go to the next segment.
To run RAMP AND SOAK, CN616TC1 must be installed and set up as
described in STANDARD MODE, then MODEL mode must be
changed to 51 or 52 function 33 [p37]. Set number of segments function
74 [p33]. And set segments function 75 sub function 01 to 20 [p34].
When all is set correctly to run PROFILE it must be started by function
79 [p37]. Until PROFILE is started controller will run in STANDARD
MODE, controlling to the STANDARD MODE setpoint. Function 79
will start profile for any single zone, or all zones at once. In the first
segment starting setpoint is set at the ambient temperature and is changed
at the rate of slope of the first segment.
