A two-position controller is able to control the heating. A three-position controller can control
heating and cooling.
By setting bit 10 to “1” the result of the self optimisation influenced. The response to disturbances
becomes faster. The controlling however becomes less stable.
NOTE To validate changes of the operation mode valid, bit 0 of the buffer memory address 340
must be switched ON after changing of the operation mode (refer to 3.3.16).

0
Bit 0 = 1: Two-position controller
Bit 0 = 0: Three-position controller
Bit 1 = 1: Thermocouple input
Bit 2 = 1: KTY input
Bit 3 = 1: Voltage input (0 to10 V DC)
Selection of the type of thermocouple with bit 8 and bit 9:
0 0: Thermocouple type L
0 1: Thermocouple type J
1 0: Thermocouple type K
1 1: Thermocouple type U
Bit 10 = 1: Response enlargement during self
optimisation by 1.2
