Installed a Santon Prem Plus in college today and whilst wiring up i realised that i was missing the Santon control relay - my tutor said 'dont worry just wire from HW ON to the cylinder hi-limit stat then back to the wiring center to switch the 2 port,3-port, boiler and pump.
Is this correct? - why do i need to use the control relay? (which i'm guessing that you have to).
BTW its a 3-port and 2-port set up.
