Big ideas, small footprint
One of the biggest restrictions when designing the system was the size of the plant room. Harry explained that this was quite common in residential developments, where architects do not necessarily consider the space needed for advanced building management systems (BMS).
The solution, he went on, was WAGO’s 750 series programmable logic controller (PLC).
“Generally speaking, you wouldn’t use a PLC in residential building control – they are more for industrial applications,” Harry said, “but a normal BMS panel is about four times the size of the WAGO PLC.”
What’s more, because it is designed for industrial use, “it is very robust,” Harry went on, adding that the team also used WAGO terminals for underfloor heating manifolds.
“These are usually stuck behind cupboards,” he explained. “The WAGO clamp system means there are no screws on the terminals, so they are maintenance free – you don’t have to check the screws each year to make sure none are loose. This is a huge plus on residential properties.”
In addition, WAGO’s automation system is open source and vendor agnostic at field level. This, combined with the flexibility provided by the WAGO CODESYS Software, this allowed Accurro to “put their own stamp” on the solution, and tailor it to meet the needs of their end user, Harry added.
