7.1 Master telegram
The following telegrams sent by the master are supported by KS 50-1 TCont.
… 4 5 6 ... 12 13+14
... Identification Message Check sum
Byte 5: Identification: 41h (‚A‘) and 52h (‚R‘) is supported.
Byte 6-9: Set-point (= SP) in 0,1 degrees Celsius
(3 digits before, 1 digit behind the decimal point);
negative temperatures up to –99 degrees Celsius are possible
(1st byte = 2Dh)
Range: -99,9 ... 999,9 °C
Examples: 12,3 °C → 30h 31h 32h 33h
-5,6 °C → 2Dh 30h 35h 36h
Byte 10: Mould type = parameter set:
60h (`): is supported (self-tuning acc. to KS 50-1 TCont setting)
61h (a)...6Ah(j): commands are accepted; function as 60h
Byte 11: Control commands = operating mode:
61h (a), 6Bh (k): Switch-off function;
cooling down to return flow temperature, switch off
feedback signals: (k) cooling, (p) switched off
70h (p): Switch-off function;
heating off, cooling down to return flow temperature,
cooling off, pump off, switch off
feedback signals: (k) cooling, (p) switched off
72h (r ): Switch-on function;
pump on, self-tuning on (if permitted),
closed-loop control (normal operation)
feedback signals: (r ) closed-loop control
73h (s): Switch-off function;
cooling down to return flow temperature, switch off
feedback signals: (s) cooling, (p) switched off
Byte 12: Reserved, always 20h
Byte 13,14: Checksum
