C – Programming relays functions
1. Controller has two relays, each of them can be configured independently.
2. Each relay has own parameter which decide about its application.
3. It is not allowed to assign the same function for two relays because only one is supported at the
same time.
4. Relay P1 was assigned with r2 parameter.
5. Relay P2 was assigned with r1 parameter.
6. Relays can be assigned with following functions:
0- Unused
1- Block 1 cooling
2- Block 1 heating
3- Overheating alarm for block 1
4- Overcooling alarm for block 1
5- Block alarm (any block)
6- Block 2 cooling
7- Block 2 heating
8- Overheating alarm for block 2
9- Overcooling alarm for block 2
10- any alarm – block 2
Each relay can be controlled by block 1 or block 2.
7. Function programming is available from the Service Parameters Programming level.
8. Relays should be (look at point 1).
9. There is a possibility not to connect any relay to block – the block serves as a thermometer then.
D – Programming of user parameters
1. To switch on parameters programming mode button has to be pressed. After that a diode
on a button is lighted, it means programming mode is active. For a second name of
parameter ‘u1’ will appear on the display and then the value of this parameter. This value could be
changed by using or buttons, in range:
U1: ‘d0’ – ‘d1 - 1’;
U2: ‘u1+ 1’ – ‘d1’;
U3: ‘d0’ – ‘d1 - 1’;
U4: ‘u3+ 1’ – ‘d1’;
2. By pressing button again you save the parameter ‘u1’ value and switch to programming
the next parameter.
3. Depending on the programming of parameters r5 and r6 the list of user parameters may change.
4. If ‘r5’=1 parameters ‘u1’ o ‘u2’ can be programmed; If ‘r5’=2 only parameter ‘u1’ can be
programmed.
