Tyrvään Pappila is a versatile event house in Sastamala. Originally built as a rectory in 1889, it was rebuilt in 2017 to its former splendor. In connection with the renovation, the property heating system was completely renewed.

The rectory uses a WTT Onda three-circuit heat distribution unit with a total power of 240 kW. Automatic control is provided by the Vexve AM45 heating controller, expanded with extra AM40 heat control for 5 circuits. Vexve's small steel ball valves are also used in the distribution unit.

HVAC planning was the responsibility of consultant company Suunnittelu Räsänen.
