This question is regarding Mira Excel/Select Thermostatic Cartridge - 903.33

Miira Excel Cartridge pressure setting

Could not find any instructions for setting high or low pressure with my new cartridge. Does this setting mode refure to the hot or cold water?

There should be a red key that fits in to two holes at the back of the cartridge high and low stamped into the back of the cartridge using the key you turn the back of the cartridge to high or low.

 

High for combi boilers and pumps over 2bar

Low for gravity systems and pumps under 2bar
