So I'm looking to have this set up, I have three zones + DHW

2 of those zones are underfloor heating connected to heatmiser uh4 and then there is a radiator zone for upstairs

My question is, can hot water priority be set up when there are three seperate 2 way zone valves, one for the underfloor heating, one for the radiators and then the other for the DHW

Forgot to add, the radiator zone and underfloor heating zone valves are both fitted with drayton zone actuators
