Hi, a few weeks back i started a job on six new apartments, they were to have combi boilers for heating and hot water but the developer changed his mind and deciced to go all electric! great! The heating system he opted for were panel heaters controlled by a central room stat. I wired the system as per the diagram supplied by the heating company.
32 amp supply from c.u to 32 amp relay module(supplied by them) cable along with cable from stat, then on to a another c.u supplying the individual heaters.
I picked up the controls today to start second fix and they have supplied 25 amp 4 pole contactors, not a 32 amp relay module as per supplied paperwork, one per apartment.
I rang them to query this and they told me to bridge across 3 of the poles???
