    Why use an On /Off Temperature Controller?

    Used for monitoring purposes in heating environments, on-off temperature controllers prevent rapid increases in temperature that could cause damage. These controllers are often used where there isn't a need for precision temperature control, but where a system is unable to handle continuous interruptions. A typical example of an on-off controller is a thermostat in a system, if the temperature drops below the pre-set level the system is switched on. They can protect against a system of over-heating or over-cooling and have an 'on' 'off' option with no middle state.

    Does this display Celsius or Fahrenheit?

    This temperature controller displays temperatures in Celsius and Fahrenheit.

    Can it be password protected?

    Yes, this controller features password protection.

    Can this control heating and cooling?

    The RS PRO temperature controller is suitable for heating and cooling control.
