PTC thermistor tripping unit	PTC thermistor triggering relay for switch cabinet installation (1 device per motor required). The thermistor overload relays monitor motors which are equipped with PTC thermistor temperature sensors. The temperature sensors are installed in the windings of the motors and measure the heating up of the motor directly. This enables direct monitoring and evaluation of various operating conditions. A collective fault signal (SSM) is possible with corresponding wiring in the switch cabinet.

Surcharge for thermistor sensor (dual pumps)	With pumps of the K3 variant (available at additional charge), three thermistors/temperature sensors are installed in the windings of the motors and directly measure the motor heating. This allows direct control of the operating condition of the motor while simultaneously ensuring appropriate motor protection.

Recommended services
Commissioning	Commissioning Glanded pumps	2219391
	For perfect functioning of the pump(s) / system(s), it is recommended to have the commissioning carried out by the works' own WILO SE Customer Service Department. Optimum setting and efficient operation of the system are ensured as a result. Commissioning is comprised of the following points: Commissioning of system(s) according to checklist Parameterisation and setting of switchgear Testing and adaptation of initial compressing of pressure tanks (filling up to 80 litres incl.) Functional check of fitted system(s) Practice-oriented operation instruction Wilo commissioning protocol The price for commissioning only applies to system(s) which have been installed in accordance with the installation and operating instructions and state-of-the-art technology. No costs for any materials which may be required are included.
