Help on Mitsubishi air source unit wiring

[714gold714]

Hello all

im currently first fixing for a Mitsubishi outdoor unit- puhz-sw120vha indoor unit-ehscmec

the system has an air course unit located outside, joule cylinder in loft, hydro box next to fuseboard

manifold for under floor heating downstairs which I have ran all my three core wires for my thermostats downstairs zones to this, also ran a feed and three core back to the hydrobox

Manifold for upstairs under floor heating I have ran all my three cores wires for my thermostats for upstairs zones to this, also ran a feed and three core back to hydrobox

my main question is currently I'm unsure where the zone valves will be I presume on the joule cylinder in the loft? What wires would you run to the cylinder from the hydro box? To turn on heating and hot water


thanks in advance

Hi bud,a bit more information on the system and cylinder is required. Joule make a range of cylinders,direct and indirect,and the system designer should indicate where your cabling should be.

Email the plumber at home,now...that'll teach him...irate:
