MAKING MODERN LIVING POSSIBLE Temperature controls, Type KP KP temperature controls are single-pole, double-throw (SPDT) temperature-operated electric switches. A KP temperature control can be connected directly to a single-phase AC motor of up to approx. 2 kW or installed in the control circuit of DC motors and large AC motors. KP temperature controls are used for regulation, but can also be seen in safety monitoring systems. KP temperature controls are available with vapour charge or with adsorption charge. With vapour charge the differential is very small. KP thermostats with adsorption...

To avoid the temperature of the hot gas exceeding the maximum permissible value during extreme operating conditions (low evaporating...

Technical brochure Temperature controls, type KP Temperature controls with automatic reset Set the upper activating temperature on the range scale. Set the differential on the "DIFF" scale. The temperature setting on the range scale will then correspond to the temperature at which the refrigeration compressor will be started on rising temperature. The compressor will be stopped when the temperature has fallen in relation to the differential setting. Note that the differential depends on the range setting. Therefore, the differential scale must only be used as guideline. If with low stop...
