What it is
The Vaillant high pressure sensor (part number 0020210697) is a pressure sensing component used on Vaillant heat pump appliances. It monitors system pressure and feeds that reading back to the appliance's control electronics. It is fitted across Arotherm air source heat pumps and Flexotherm VWF units.
