Control behavior (P01)
The factory setting for control is “PID slow”, ideal for most heating systems. Optimum control
can be selected if control does not provide the desired result:
2-position controller with 1 [K] switching hysteresis
● For systems with small capacity that appear slow
● For applications requiring extended runtimes or where frequent switching causes
problems
● For difficult control loops where hunting may result
Typical applications:
● Dry floor heating systems
● Heat pumps
● Electric heating with contactors
● 2-position controller with 0.5 [K] switching hysteresis.
● For general control situations. Provides better comfort than 1 [K] switching hysteresis.
● Can also be used for difficult control situations.
PID control behavior for slow heating systems that require longer minimum On times and a
limited number of switching cycles per hour.
Typical applications:
● Wet floor heating systems, oil fired boilers
● Can also be used for all other types of heating applications. (Alternative setting)
PID control behavior for fast heating systems that tolerate a high number of switching cycles.
Typical applications:
● Electric heaters with current valve
● Gas boilers
● Fast thermal actuators
Backup
When removing the batteries, the setpoints and information required for operating mode
changeover are retained for max. 2 minutes.
