Technical description
Application:
Heating systems
Functions:
Room temperature control.
Frost protection.
Markings indicate upper and lower temperature range; two energy saving clips can be used to limit settings.
Temperature range is limited on both ends and can be blocked using covered stop clips.
Control behavior:
Proportional controller without auxilliary energy. Liquid-filled thermostat. High pressure power, lowest hysteresis, optimal closing time.
Stable control behavior even in the case of small calculated p-band variation (<1K).
Nominal temperature range:
