Building Automation on the iPad

Low energy consumption was one of the main goals that Günther Heumann pursued when he was planning his new corporate headquarters. At the same time, he wanted to demonstrate modern building automation to his customers. A WAGO ETHERNET Controller and an app for the iPad form the basis of the building automation.

The new corporate headquarters for Elektro-Service Heumann GmbH offers CEO Günther Heumann and his ten employees 400 m² of office and storage space. During planning, special focus was placed on providing optimal comfort in the space while keeping energy costs low. For example, the south-facing facade is nearly all glass, allowing the sun to warm up the rooms during the colder seasons. Blinds ensure that the temperature does not climb too high in the summer. A wood-fired furnace with an output of 14.5 kW provides the building with warm-air heat if the solar radiation alone is not sufficient.

In cold weather, a cross-stream heat exchanger uses the exhaust air to warm the supply air so that very little energy is required for heating.

To accomplish this, ground heat collectors were situated under the parking garage; these use a brine pipeline and a heat exchanger to cool the supply air.

Central Air-Conditioning Control

Günther Heumann uses the WAGO-I/O-SYSTEM with the 750-881 ETHERNET Controller to automate the air-conditioning system. The ETHERNET Controller adjusts the supply and exhaust air flaps in the individual rooms, the cross-stream heat exchanger, the ventilator motors, the heating, the pump for cooling and the SMI drives for the blinds. Temperature sensors in the rooms provide the current actual value; the controller compares this to the setpoint specified by the user in order to adjust the ventilation flaps accordingly. The WAGO-I/O-SYSTEM thus automatically controls the entire air-conditioning system. Günther Heumann and his team created the CODESYS programming themselves in accordance with IEC 61131-3.
