HEAt with SP1 and CooL with “SP2” [status]
(see “Note about digital inputs”);
7
Timer Run/Hold/Reset [transition].
A short closure allows to start timer execution
and to suspend it while a long closure (longer
than 10 seconds) allows to reset the timer;
8
Timer Run [transition]. A short closure allows to
start timer execution;
9
Timer reset [transition]. A short closure allows
to reset timer count;
10
Timer run/hold [Status]:
- Contact close = timer RUN;
- Contact open = timer Hold.
11
Timer run/reset [status];
12
Timer run/reset with a special “lock” at the end of
the time count (in order to restart the time count
the instrument must detect a run command com-
ing from serial link keyboard or digital input 2);
13
Program Run [transition].
The first closure allows to start program execu-
tion but a second closure restart the program
execution from the beginning;
14
Program Reset [transition].
A contact closure allows to reset program execution;
15
Program Hold [transition].
The first closure allows to hold program execution
and a second closure continue program execution;
16
Program Run/Hold [status].
When the contact is closed the program is running;
17
Program Run/Reset [status].
- Contact closed - Program run;
- Contact open - Program reset;
18
Sequential Set Point selection [transition]
(see “Note about digital inputs”);
19
SP1/SP2 selection [status];
20
Binary selection of the Set Point made by digital
input 1 (less significant bit) and digital input 2
(most significant bit) [status];
21
Digital input 1 will work in parallel with the
button while digital input 2 will work in parallel
with the
button.
Notes: 1.
When [10] diF1 or [11] diF2 (e.g. diF1) are equal
to 6 the instrument operates as follows:
•
When the contact is open, the control action is
an heating action and the active Set Point is SP.
•
When the contact is closed, the control action is
a cooling action and the active Set Point is SP2.
2.
When [10] diF1 = 20, [11] diF2 is forced to 20 and
cannot perform another function.
3.
When [10] diF1 = 20 and [11] diF2 = 20, the SP se-
lection will be in accordance with the following table:
Digital Input 1 Digital Input 2 Operative Set Point
Off
Off
Set Point 1
On
Off
Set Point 2
Off
On
Set Point 3
On
On
Set Point 4
4.
When [10] diF1 is equal to 21, [11] diF2 is forced
to 21 (up.du) and cannot perform another function.
5.
When a “Sequential Set Point selection” is used
(diF1 or diF2 = 18), every closure of the logic
input increases the value of SPAT (active Set
Point) of one step. The selection is cyclic:
SP
->
SP2
->
SP3
->
SP4
.
6.
Setting [10] diF1 or [11] diF2 equal to 6 the
instrument makes the [66] tcH, [67] rcG and
[68] tcc parameters available.
